vmagent
vmagent
is a tiny but mighty agent which helps you collect metrics from various sources
and store them in VictoriaMetrics
or any other Prometheus-compatible storage systems that support the remote_write
protocol.
Motivation
While VictoriaMetrics provides an efficient solution to store and observe metrics, our users needed something fast
and RAM friendly to scrape metrics from Prometheus-compatible exporters into VictoriaMetrics.
Also, we found that our user's infrastructure are like snowflakes in that no two are alike. Therefore we decided to add more flexibility
to vmagent
such as the ability to push metrics instead of pulling them. We did our best and will continue to improve vmagent.
Features
- Can be used as a drop-in replacement for Prometheus for scraping targets such as node_exporter. See Quick Start for details.
- Can add, remove and modify labels (aka tags) via Prometheus relabeling. Can filter data before sending it to remote storage. See these docs for details.
- Accepts data via all ingestion protocols supported by VictoriaMetrics:
- Influx line protocol via
http://<vmagent>:8429/write
. See these docs. - Graphite plaintext protocol if
-graphiteListenAddr
command-line flag is set. See these docs. - OpenTSDB telnet and http protocols if
-opentsdbListenAddr
command-line flag is set. See these docs. - Prometheus remote write protocol via
http://<vmagent>:8429/api/v1/write
. - JSON lines import protocol via
http://<vmagent>:8429/api/v1/import
. See these docs. - Native data import protocol via
http://<vmagent>:8429/api/v1/import/native
. See these docs. - Data in Prometheus exposition format. See these docs for details.
- Arbitrary CSV data via
http://<vmagent>:8429/api/v1/import/csv
. See these docs.
- Influx line protocol via
- Can replicate collected metrics simultaneously to multiple remote storage systems.
- Works smoothly in environments with unstable connections to remote storage. If the remote storage is unavailable, the collected metrics
are buffered at
-remoteWrite.tmpDataPath
. The buffered metrics are sent to remote storage as soon as the connection to the remote storage is repaired. The maximum disk usage for the buffer can be limited with-remoteWrite.maxDiskUsagePerURL
. - Uses lower amounts of RAM, CPU, disk IO and network bandwidth compared with Prometheus.
- Scrape targets can be spread among multiple
vmagent
instances when big number of targets must be scraped. See these docs. - Can efficiently scrape targets that expose millions of time series such as /federate endpoint in Prometheus. See these docs.
- Can deal with high cardinality and high churn rate issues by limiting the number of unique time series sent to remote storage systems. See these docs.
Quick Start
Please download vmutils-*
archive from releases page, unpack it
and configure the following flags to the vmagent
binary in order to start scraping Prometheus targets:
-promscrape.config
with the path to Prometheus config file (usually located at/etc/prometheus/prometheus.yml
)-remoteWrite.url
with the remote storage endpoint such as VictoriaMetrics, the-remoteWrite.url
argument can be specified multiple times to replicate data concurrently to an arbitrary number of remote storage systems.
Example command line:
/path/to/vmagent -promscrape.config=/path/to/prometheus.yml -remoteWrite.url=https://victoria-metrics-host:8428/api/v1/write
If you only need to collect Influx data, then the following command is sufficient:
/path/to/vmagent -remoteWrite.url=https://victoria-metrics-host:8428/api/v1/write
Then send Influx data to http://vmagent-host:8429
. See these docs for more details.
vmagent
is also available in docker images.
Pass -help
to vmagent
in order to see the full list of supported command-line flags with their descriptions.
Configuration update
vmagent
should be restarted in order to update config options set via command-line args.
vmagent
supports multiple approaches for reloading configs from updated config files such as -promscrape.config
, -remoteWrite.relabelConfig
and -remoteWrite.urlRelabelConfig
:
-
Sending
SUGHUP
signal tovmagent
process:kill -SIGHUP `pidof vmagent`
-
Sending HTTP request to
http://vmagent:8429/-/reload
endpoint.
There is also -promscrape.configCheckInterval
command-line option, which can be used for automatic reloading configs from updated -promscrape.config
file.
Use cases
IoT and Edge monitoring
vmagent
can run and collect metrics in IoT and industrial networks with unreliable or scheduled connections to their remote storage.
It buffers the collected data in local files until the connection to remote storage becomes available and then sends the buffered
data to the remote storage. It re-tries sending the data to remote storage until any errors are resolved.
The maximum buffer size can be limited with -remoteWrite.maxDiskUsagePerURL
.
vmagent
works on various architectures from the IoT world - 32-bit arm, 64-bit arm, ppc64, 386, amd64.
See the corresponding Makefile rules for details.
Drop-in replacement for Prometheus
If you use Prometheus only for scraping metrics from various targets and forwarding those metrics to remote storage
then vmagent
can replace Prometheus. Typically, vmagent
requires lower amounts of RAM, CPU and network bandwidth compared with Prometheus.
See these docs for details.
Replication and high availability
vmagent
replicates the collected metrics among multiple remote storage instances configured via -remoteWrite.url
args.
If a single remote storage instance temporarily is out of service, then the collected data remains available in another remote storage instance.
vmagent
buffers the collected data in files at -remoteWrite.tmpDataPath
until the remote storage becomes available again and then it sends the buffered data to the remote storage in order to prevent data gaps.
Relabeling and filtering
vmagent
can add, remove or update labels on the collected data before sending it to the remote storage. Additionally,
it can remove unwanted samples via Prometheus-like relabeling before sending the collected data to remote storage.
Please see these docs for details.
Splitting data streams among multiple systems
vmagent
supports splitting the collected data between muliple destinations with the help of -remoteWrite.urlRelabelConfig
,
which is applied independently for each configured -remoteWrite.url
destination. For example, it is possible to replicate or split
data among long-term remote storage, short-term remote storage and a real-time analytical system built on top of Kafka.
Note that each destination can receive it's own subset of the collected data due to per-destination relabeling via -remoteWrite.urlRelabelConfig
.
Prometheus remote_write proxy
vmagent
can be used as a proxy for Prometheus data sent via Prometheus remote_write
protocol. It can accept data via the remote_write
API
at the/api/v1/write
endpoint. Then apply relabeling and filtering and proxy it to another remote_write
system .
The vmagent
can be configured to encrypt the incoming remote_write
requests with -tls*
command-line flags.
Also, Basic Auth can be enabled for the incoming remote_write
requests with -httpAuth.*
command-line flags.
remote_write for clustered version
While vmagent
can accept data in several supported protocols (OpenTSDB, Influx, Prometheus, Graphite) and scrape data from various targets, writes are always peformed in Promethes remote_write protocol. Therefore for the clustered version, -remoteWrite.url
the command-line flag should be configured as <schema>://<vminsert-host>:8480/insert/<accountID>/prometheus/api/v1/write
according to these docs. There is also support for multitenant writes. See these docs.
Multitenancy
By default vmagent
collects the data without tenant identifiers and routes it to the configured -remoteWrite.url
. But it can accept multitenant data if -remoteWrite.multitenantURL
is set. In this case it accepts multitenant data at http://vmagent:8429/insert/<accountID>/...
in the same way as cluster version of VictoriaMetrics does according to these docs and routes it to <-remoteWrite.multitenantURL>/insert/<accountID>/prometheus/api/v1/write
. If multiple -remoteWrite.multitenantURL
command-line options are set, then vmagent
replicates the collected data across all the configured urls. This allows using a single vmagent
instance in front of VictoriaMetrics clusters for processing the data from all the tenants.
How to collect metrics in Prometheus format
Specify the path to prometheus.yml
file via -promscrape.config
command-line flag. vmagent
takes into account the following
sections from Prometheus config file:
global
scrape_configs
All other sections are ignored, including the remote_write section.
Use -remoteWrite.*
command-line flag instead for configuring remote write settings.
The following scrape types in scrape_config section are supported:
static_configs
- is for scraping statically defined targets. See these docs for details.file_sd_configs
- is for scraping targets defined in external files (aka file-based service discover). See these docs for detailskubernetes_sd_configs
- for scraping targets in Kubernetes (k8s). See kubernetes_sd_config for details.ec2_sd_configs
- is for scraping targets in Amazon EC2. See ec2_sd_config for details.vmagent
doesn't support theprofile
config param yet.gce_sd_configs
- is for scraping targets in Google Compute Engine (GCE). See gce_sd_config for details.vmagent
provides the following additional functionality forgce_sd_config
:- if
project
arg is missing thenvmagent
uses the project for the instance where it runs; - if
zone
arg is missing thenvmagent
uses the zone for the instance where it runs; - if
zone
arg is equal to"*"
, thenvmagent
discovers all the zones for the given project; zone
may contain an arbitrary number of zones, i.e.zone: [us-east1-a, us-east1-b]
.
- if
consul_sd_configs
- is for scraping the targets registered in Consul. See consul_sd_config for details.dns_sd_configs
- is for scraping targets discovered from DNS records (SRV, A and AAAA). See dns_sd_config for details.openstack_sd_configs
- is for scraping OpenStack targets. See openstack_sd_config for details. OpenStack identity API v3 is supported only.docker_sd_configs
- is for scraping Docker targets. See docker_sd_config for details.dockerswarm_sd_configs
- is for scraping Docker Swarm targets. See dockerswarm_sd_config for details.eureka_sd_configs
- is for scraping targets registered in Netflix Eureka. See eureka_sd_config for details.digitalocean_sd_configs
is for scraping targerts registered in DigitalOcean See digitalocean_sd_config for details.http_sd_configs
is for scraping targerts registered in http service discovery. See http_sd_config for details.
Please file feature requests to our issue tracker if you need other service discovery mechanisms to be supported by vmagent
.
vmagent
also support the following additional options in scrape_configs
section:
disable_compression: true
- to disable response compression on a per-job basis. By defaultvmagent
requests compressed responses from scrape targets to save network bandwidth.disable_keepalive: true
- to disable HTTP keep-alive connections on a per-job basis. By default,vmagent
uses keep-alive connections to scrape targets to reduce overhead on connection re-establishing.stream_parse: true
- for scraping targets in a streaming manner. This may be useful for targets exporting big number of metrics. See these docs.
Note that vmagent
doesn't support refresh_interval
option for these scrape configs. Use the corresponding -promscrape.*CheckInterval
command-line flag instead. For example, -promscrape.consulSDCheckInterval=60s
sets refresh_interval
for all the consul_sd_configs
entries to 60s. Run vmagent -help
in order to see default values for the -promscrape.*CheckInterval
flags.
The file pointed by -promscrape.config
may contain %{ENV_VAR}
placeholders which are substituted by the corresponding ENV_VAR
environment variable values.
Adding labels to metrics
Labels can be added to metrics by the following mechanisms:
- The
global -> external_labels
section in-promscrape.config
file. These labels are added only to metrics scraped from targets configured in the-promscrape.config
file. They aren't added to metrics collected via other data ingestion protocols. - The
-remoteWrite.label
command-line flag. These labels are added to all the collected metrics before sending them to-remoteWrite.url
. For example, the following command will startvmagent
, which will add{datacenter="foobar"}
label to all the metrics pushed to all the configured remote storage systems (all the-remoteWrite.url
flag values):
/path/to/vmagent -remoteWrite.label=datacenter=foobar ...
Relabeling
vmagent
supports Prometheus relabeling.
and also provides the following actions:
replace_all
: replaces all of the occurences ofregex
in the values ofsource_labels
with thereplacement
and stores the results in thetarget_label
.labelmap_all
: replaces all of the occurences ofregex
in all the label names with thereplacement
.keep_if_equal
: keeps the entry if all the label values fromsource_labels
are equal.drop_if_equal
: drops the entry if all the label values fromsource_labels
are equal.
The relabeling can be defined in the following places:
- At the
scrape_config -> relabel_configs
section in-promscrape.config
file. This relabeling is applied to target labels. This relabeling can be debugged by passingrelabel_debug: true
option to the correspondingscrape_config
section. In this casevmagent
logs target labels before and after the relabeling and then drops the logged target. - At the
scrape_config -> metric_relabel_configs
section in-promscrape.config
file. This relabeling is applied to all the scraped metrics in the givenscrape_config
. This relabeling can be debugged by passingmetric_relabel_debug: true
option to the correspondingscrape_config
section. In this casevmagent
logs metrics before and after the relabeling and then drops the logged metrics. - At the
-remoteWrite.relabelConfig
file. This relabeling is aplied to all the collected metrics before sending them to remote storage. This relabeling can be debugged by passing-remoteWrite.relabelDebug
command-line option tovmagent
. In this casevmagent
logs metrics before and after the relabeling and then drops all the logged metrics instead of sending them to remote storage. - At the
-remoteWrite.urlRelabelConfig
files. This relabeling is applied to metrics before sending them to the corresponding-remoteWrite.url
. This relabeling can be debugged by passing-remoteWrite.urlRelabelDebug
command-line options tovmagent
. In this casevmagent
logs metrics before and after the relabeling and then drops all the logged metrics instead of sending them to the corresponding-remoteWrite.url
.
You can read more about relabeling in the following articles:
- How to use Relabeling in Prometheus and VictoriaMetrics
- Life of a label
- Discarding targets and timeseries with relabeling
- Dropping labels at scrape time
- Extracting labels from legacy metric names
- relabel_configs vs metric_relabel_configs
Prometheus staleness markers
Starting from v1.64.0, vmagent
sends Prometheus staleness markers for scraped metrics when the scrape target is removed from the list of targets. Prometheus staleness markers aren't sent in stream parsing mode or if -promscrape.disableStaleMarkers
command-line is set.
Stream parsing mode
By default vmagent
reads the full response from scrape target into memory, then parses it, applies relabeling and then pushes the resulting metrics to the configured -remoteWrite.url
. This mode works good for the majority of cases when the scrape target exposes small number of metrics (e.g. less than 10 thousand). But this mode may take big amounts of memory when the scrape target exposes big number of metrics. In this case it is recommended enabling stream parsing mode. When this mode is enabled, then vmagent
reads response from scrape target in chunks, then immediately processes every chunk and pushes the processed metrics to remote storage. This allows saving memory when scraping targets that expose millions of metrics. Stream parsing mode may be enabled either globally for all of the scrape targets by passing -promscrape.streamParse
command-line flag or on a per-scrape target basis with stream_parse: true
option. For example:
scrape_configs:
- job_name: 'big-federate'
stream_parse: true
static_configs:
- targets:
- big-prometeus1
- big-prometeus2
honor_labels: true
metrics_path: /federate
params:
'match[]': ['{__name__!=""}']
Note that sample_limit
option doesn't prevent from data push to remote storage if stream parsing is enabled because the parsed data is pushed to remote storage as soon as it is parsed.
Scraping big number of targets
A single vmagent
instance can scrape tens of thousands of scrape targets. Sometimes this isn't enough due to limitations on CPU, network, RAM, etc.
In this case scrape targets can be split among multiple vmagent
instances (aka vmagent
horizontal scaling, sharding and clustering).
Each vmagent
instance in the cluster must use identical -promscrape.config
files with distinct -promscrape.cluster.memberNum
values.
The flag value must be in the range 0 ... N-1
, where N
is the number of vmagent
instances in the cluster.
The number of vmagent
instances in the cluster must be passed to -promscrape.cluster.membersCount
command-line flag. For example, the following commands
spread scrape targets among a cluster of two vmagent
instances:
/path/to/vmagent -promscrape.cluster.membersCount=2 -promscrape.cluster.memberNum=0 -promscrape.config=/path/to/config.yml ...
/path/to/vmagent -promscrape.cluster.membersCount=2 -promscrape.cluster.memberNum=1 -promscrape.config=/path/to/config.yml ...
By default each scrape target is scraped only by a single vmagent
instance in the cluster. If there is a need for replicating scrape targets among multiple vmagent
instances,
then -promscrape.cluster.replicationFactor
command-line flag must be set to the desired number of replicas. For example, the following commands
start a cluster of three vmagent
instances, where each target is scraped by two vmagent
instances:
/path/to/vmagent -promscrape.cluster.membersCount=3 -promscrape.cluster.replicationFactor=2 -promscrape.cluster.memberNum=0 -promscrape.config=/path/to/config.yml ...
/path/to/vmagent -promscrape.cluster.membersCount=3 -promscrape.cluster.replicationFactor=2 -promscrape.cluster.memberNum=1 -promscrape.config=/path/to/config.yml ...
/path/to/vmagent -promscrape.cluster.membersCount=3 -promscrape.cluster.replicationFactor=2 -promscrape.cluster.memberNum=2 -promscrape.config=/path/to/config.yml ...
If each target is scraped by multiple vmagent
instances, then data deduplication must be enabled at remote storage pointed by -remoteWrite.url
.
See these docs for details.
Scraping targets via a proxy
vmagent
supports scraping targets via http, https and socks5 proxies. Proxy address must be specified in proxy_url
option. For example, the following scrape config instructs
target scraping via https proxy at https://proxy-addr:1234
:
scrape_configs:
- job_name: foo
proxy_url: https://proxy-addr:1234
Proxy can be configured with the following optional settings:
proxy_authorization
for generic token authorization. See Prometheus docs for details on authorization sectionproxy_bearer_token
andproxy_bearer_token_file
for Bearer token authorizationproxy_basic_auth
for Basic authorization. See these docs.proxy_tls_config
for TLS config. See these docs.
For example:
scrape_configs:
- job_name: foo
proxy_url: https://proxy-addr:1234
proxy_basic_auth:
username: foobar
password: secret
proxy_tls_config:
insecure_skip_verify: true
cert_file: /path/to/cert
key_file: /path/to/key
ca_file: /path/to/ca
server_name: real-server-name
Cardinality limiter
By default vmagent
doesn't limit the number of time series written to remote storage systems specified at -remoteWrite.url
. The limit can be enforced by setting the following command-line flags:
-remoteWrite.maxHourlySeries
- limits the number of unique time seriesvmagent
can write to remote storage systems during the last hour. Useful for limiting the number of active time series.-remoteWrite.maxDailySeries
- limits the number of unique time seriesvmagent
can write to remote storage systems during the last day. Useful for limiting daily churn rate.
Both limits can be set simultaneously. If any of these limits is reached, then samples for new time series are dropped instead of sending them to remote storage systems. A sample of dropped series is put in the log with WARNING
level.
The exceeded limits can be monitored with the following metrics:
vmagent_hourly_series_limit_rows_dropped_total
- the number of metrics dropped due to exceeded hourly limit on the number of unique time series.vmagent_daily_series_limit_rows_dropped_total
- the number of metrics dropped due to exceeded daily limit on the number of unique time series.
These limits are approximate, so vmagent
can underflow/overflow the limit by a small percentage (usually less than 1%).
Monitoring
vmagent
exports various metrics in Prometheus exposition format at http://vmagent-host:8429/metrics
page. We recommend setting up regular scraping of this page
either through vmagent
itself or by Prometheus so that the exported metrics may be analyzed later.
Use official Grafana dashboard for vmagent
state overview.
If you have suggestions for improvements or have found a bug - please open an issue on github or add a review to the dashboard.
vmagent
also exports the status for various targets at the following handlers:
-
http://vmagent-host:8429/targets
. This handler returns human-readable status for every active target. This page is easy to query from the command line withwget
,curl
or similar tools. It accepts optionalshow_original_labels=1
query arg which shows the original labels per each target before applying the relabeling. This information may be useful for debugging target relabeling. -
http://vmagent-host:8429/api/v1/targets
. This handler returns data compatible with the corresponding page from Prometheus API. -
http://vmagent-host:8429/ready
. This handler returns http 200 status code whenvmagent
finishes it's initialization for all service_discovery configs. It may be useful to performvmagent
rolling update without any scrape loss.
Troubleshooting
-
We recommend you set up the official Grafana dashboard in order to monitor the state of `vmagent'.
-
We recommend you increase the maximum number of open files in the system (
ulimit -n
) when scraping a big number of targets, asvmagent
establishes at least a single TCP connection per target. -
If
vmagent
uses too big amounts of memory, then the following options can help:- Enabling stream parsing. See these docs.
- Reducing the number of output queues with
-remoteWrite.queues
command-line option. - Reducing the amounts of RAM vmagent can use for in-memory buffering with
-memory.allowedPercent
or-memory.allowedBytes
command-line option. Another option is to reduce memory limits in Docker and/or Kuberntes ifvmagent
runs under these systems. - Reducing the number of CPU cores vmagent can use by passing
GOMAXPROCS=N
environment variable tovmagent
, whereN
is the desired limit on CPU cores. Another option is to reduce CPU limits in Docker or Kubernetes ifvmagent
runs under these systems.
-
When
vmagent
scrapes many unreliable targets, it can flood the error log with scrape errors. These errors can be suppressed by passing-promscrape.suppressScrapeErrors
command-line flag tovmagent
. The most recent scrape error per each target can be observed athttp://vmagent-host:8429/targets
andhttp://vmagent-host:8429/api/v1/targets
. -
The
/api/v1/targets
page could be useful for debugging relabeling process for scrape targets. This page contains original labels for targets dropped during relabeling (see "droppedTargets" section in the page output). By default the-promscrape.maxDroppedTargets
targets are shown here. If your setup drops more targets during relabeling, then increase-promscrape.maxDroppedTargets
command-line flag value to see all the dropped targets. Note that tracking each dropped target requires up to 10Kb of RAM. Therefore big values for-promscrape.maxDroppedTargets
may result in increased memory usage if a big number of scrape targets are dropped during relabeling. -
If
vmagent
scrapes a big number of targets then the-promscrape.dropOriginalLabels
command-line option may be passed tovmagent
in order to reduce memory usage. This option drops"discoveredLabels"
and"droppedTargets"
lists at/api/v1/targets
page, which may result in reduced debuggability for improperly configured per-target relabeling. -
If
vmagent
scrapes targets with millions of metrics per target (for example, when scraping federation endpoints), we recommend enabling stream parsing mode in order to reduce memory usage during scraping. -
We recommend you increase
-remoteWrite.queues
ifvmagent_remotewrite_pending_data_bytes
metric exported athttp://vmagent-host:8429/metrics
page grows constantly. -
If you see gaps in the data pushed by
vmagent
to remote storage when-remoteWrite.maxDiskUsagePerURL
is set, try increasing-remoteWrite.queues
. Such gaps may appear becausevmagent
cannot keep up with sending the collected data to remote storage. Therefore it starts dropping the buffered data if the on-disk buffer size exceeds-remoteWrite.maxDiskUsagePerURL
. -
vmagent
drops data blocks if remote storage replies with400 Bad Request
and409 Conflict
HTTP responses. The number of dropped blocks can be monitored viavmagent_remotewrite_packets_dropped_total
metric exported at /metrics page. -
Use
-remoteWrite.queues=1
when-remoteWrite.url
points to remote storage, which doesn't accept out-of-order samples (aka data backfilling). Such storage systems include Prometheus, Cortex and Thanos. -
vmagent
buffers scraped data at the-remoteWrite.tmpDataPath
directory until it is sent to-remoteWrite.url
. The directory can grow large when remote storage is unavailable for extended periods of time and if-remoteWrite.maxDiskUsagePerURL
isn't set. If you don't want to send all the data from the directory to remote storage then simply stopvmagent
and delete the directory. -
By default
vmagent
masks-remoteWrite.url
withsecret-url
values in logs and at/metrics
page because the url may contain sensitive information such as auth tokens or passwords. Pass-remoteWrite.showURL
command-line flag when startingvmagent
in order to see all the valid urls. -
By default
vmagent
evenly spreads scrape load in time. If a particular scrape target must be scraped at the beginning of some interval, thenscrape_align_interval
option must be used. For example, the following config aligns hourly scrapes to the beginning of hour:scrape_configs: - job_name: foo scrape_interval: 1h scrape_align_interval: 1h
-
By default
vmagent
evenly spreads scrape load in time. If a particular scrape target must be scraped at specific offset, thenscrape_offset
option must be used. For example, the following config instructsvmagent
to scrape the target at 10 seconds of every minute:scrape_configs: - job_name: foo scrape_interval: 1m scrape_offset: 10s
-
If you see
skipping duplicate scrape target with identical labels
errors when scraping Kubernetes pods, then it is likely these pods listen to multiple ports or they use an init container. These errors can either be fixed or suppressed with the-promscrape.suppressDuplicateScrapeTargetErrors
command-line flag. See the available options below if you prefer fixing the root cause of the error:The following relabeling rule may be added to
relabel_configs
section in order to filter out pods with unneeded ports:- action: keep_if_equal source_labels: [__meta_kubernetes_pod_annotation_prometheus_io_port, __meta_kubernetes_pod_container_port_number]
The following relabeling rule may be added to
relabel_configs
section in order to filter out init container pods:- action: drop source_labels: [__meta_kubernetes_pod_container_init] regex: true
