## How to install
|
||
|
||
VictoriaMetrics is distributed in the following forms:
|
||
|
||
* [Single-server-VictoriaMetrics](https://docs.victoriametrics.com/single-server-victoriametrics/) - all-in-one
|
||
binary, which is very easy to use and maintain.
|
||
Single-server-VictoriaMetrics perfectly scales vertically and easily handles millions of metrics/s;
|
||
* [VictoriaMetrics Cluster](https://docs.victoriametrics.com/cluster-victoriametrics/) - set of components
|
||
for building horizontally scalable clusters.
|
||
* [VictoriaMetrics Cloud](https://cloud.victoriametrics.com/signUp?utm_source=website&utm_campaign=docs_vm_quickstart_guide) - allows
|
||
users to run VictoriaMetrics, hosted on AWS, without the need to perform typical DevOps tasks such as proper configuration, monitoring, logs collection, access protection, software updates, backups, etc.
|
||
|
||
VictoriaMetrics is available as:
|
||
|
||
* [Docker images](https://hub.docker.com/r/victoriametrics/victoria-metrics/)
|
||
* [Helm Charts](https://github.com/VictoriaMetrics/helm-charts#list-of-charts)
|
||
* [Binary releases](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/latest)
|
||
* [Ansible Roles](https://github.com/VictoriaMetrics/ansible-playbooks)
|
||
* [Source code](https://github.com/VictoriaMetrics/VictoriaMetrics).
|
||

||
### Starting VictoriaMetrics Single Node via Docker {anchor="starting-vm-single-via-docker"}
|
||
|
||
The following commands download the latest available
|
||
[Docker image of VictoriaMetrics](https://hub.docker.com/r/victoriametrics/victoria-metrics)
|
||
and start it at port 8428, while storing the ingested data at `victoria-metrics-data` subdirectory
|
||
under the current directory:
|
||
|
||
|
||
```sh
|
||
docker pull victoriametrics/victoria-metrics:latest
|
||
docker run -it --rm -v `pwd`/victoria-metrics-data:/victoria-metrics-data -p 8428:8428 victoriametrics/victoria-metrics:latest

|
||
|
||
|
||
### Starting VictoriaMetrics Single Node from a Binary {anchor="starting-vm-single-from-a-binary"}
|
||
|
||
1. Download the correct binary for your OS and architecture from [GitHub](https://github.com/VictoriaMetrics/VictoriaMetrics/releases).
|
||
For Enterprise binaries see [this link](https://docs.victoriametrics.com/enterprise/#binary-releases).
|
||
|
||
2. Extract the archive to /usr/local/bin by running:
|
||
```sh
|
||
sudo tar -xvf <victoriametrics-archive> -C /usr/local/bin
|
||
```
|
||
Replace `<victoriametrics-archive>` with the path to the archive you downloaded in step 1.
|
||
|
||
3. Create a VictoriaMetrics user on the system:
|
||
|
||
```sh
|
||
sudo useradd -s /usr/sbin/nologin victoriametrics
|
||
```
|
||
|
||
4. Create a folder for storing VictoriaMetrics data:
|
||
|
||
```sh
|
||
mkdir -p /var/lib/victoria-metrics && chown -R victoriametrics:victoriametrics /var/lib/victoria-metrics
|
||
```
|
||
|
||
5. Create a Linux Service by running the following:
|
||
|
||
```sh
|
||
cat <<END >/etc/systemd/system/victoriametrics.service
|
||
[Unit]
|
||
Description=VictoriaMetrics service
|
||
After=network.target
|
||
|
||
[Service]
|
||
Type=simple
|
||
User=victoriametrics
|
||
Group=victoriametrics
|
||
ExecStart=/usr/local/bin/victoria-metrics-prod -storageDataPath=/var/lib/victoria-metrics -retentionPeriod=90d -selfScrapeInterval=10s
|
||
SyslogIdentifier=victoriametrics
|
||
Restart=always
|
||
|
||
PrivateTmp=yes
|
||
ProtectHome=yes
|
||
NoNewPrivileges=yes
|
||
|
||
ProtectSystem=full
|
||
|
||
[Install]
|
||
WantedBy=multi-user.target
|
||
END
|
||
```
|
||
|
||
Extra [command-line flags](https://docs.victoriametrics.com/#list-of-command-line-flags) can be added to `ExecStart` line.
|
||
|
||
If you want to deploy VictoriaMetrics Single Node as a Windows Service review the [running as a Windows service docs](https://docs.victoriametrics.com/single-server-victoriametrics/#running-as-windows-service).
|
||
|
||
> Please note, `victoriametrics` service is listening on `:8428` for HTTP connections (see `-httpListenAddr` flag).
|
||
|
||
6. Start and enable the service by running the following command:
|
||
|
||
```sh
|
||
sudo systemctl daemon-reload && sudo systemctl enable --now victoriametrics.service
|
||
```
|
||
|
||
7. Check that service started successfully:
|
||
|
||
```sh
|
||
sudo systemctl status victoriametrics.service
|
||
```
|
||
|
||
8. After VictoriaMetrics is in `Running` state, verify [vmui](https://docs.victoriametrics.com/#vmui) is working
|
||
by going to `http://<ip_or_hostname>:8428/vmui`.
|
||
|
||
|
||
### Starting VictoriaMetrics Cluster from Binaries {anchor="starting-vm-cluster-from-binaries"}
|
||
|
||
VictoriaMetrics cluster consists of [3 components](https://docs.victoriametrics.com/cluster-victoriametrics/#architecture-overview).
|
||
It is recommended to run these components in the same private network (for [security reasons](https://docs.victoriametrics.com/#security)),
|
||
but on the separate physical nodes for the best performance.
|
||
|
||
On all nodes you will need to do the following:
|
||
|
||
1. Download the correct binary for your OS and architecture with `-cluster` suffix from [GitHub](https://github.com/VictoriaMetrics/VictoriaMetrics/releases).
|
||
For Enterprise binaries see [this link](https://docs.victoriametrics.com/enterprise/#binary-releases).
|
||
|
||
2. Extract the archive to /usr/local/bin by running:
|
||
|
||
```sh
|
||
sudo tar -xvf <victoriametrics-archive> -C /usr/local/bin
|
||
```
|
||
|
||
Replace `<victoriametrics-archive>` with the path to the archive you downloaded in step 1
|
||
|
||
3. Create a user account for VictoriaMetrics:
|
||
|
||
```sh
|
||
sudo useradd -s /usr/sbin/nologin victoriametrics
|
||
```
|
||
|
||
See recommendations for installing each type of [cluster component](https://docs.victoriametrics.com/cluster-victoriametrics/#architecture-overview) below.
|
||
|
||
##### Installing vmstorage
|
||
|
||
1. Create a folder for storing `vmstorage` data:
|
||
|
||
`mkdir -p /var/lib/vmstorage && chown -R victoriametrics:victoriametrics /var/lib/vmstorage`
|
||
|
||
2. Create a Linux Service for `vmstorage` service by running the following command:
|
||
|
||
```sh
|
||
cat <<END >/etc/systemd/system/vmstorage.service
|
||
[Unit]
|
||
Description=VictoriaMetrics vmstorage service
|
||
After=network.target
|
||
|
||
[Service]
|
||
Type=simple
|
||
User=victoriametrics
|
||
Group=victoriametrics
|
||
Restart=always
|
||
ExecStart=/usr/local/bin/vmstorage-prod -retentionPeriod=90d -storageDataPath=/var/lib/vmstorage
|
||
|
||
PrivateTmp=yes
|
||
NoNewPrivileges=yes
|
||
ProtectSystem=full
|
||
|
||
[Install]
|
||
WantedBy=multi-user.target
|
||
END
|
||
```
|
||
|
||
Extra [command-line flags](https://docs.victoriametrics.com/cluster-victoriametrics/#list-of-command-line-flags-for-vmstorage)
|
||
for vmstorage can be added to `ExecStart` line.
|
||
|
||
> Please note, `vmstorage` service is listening on `:8400` for vminsert connections (see `-vminsertAddr` flag),
|
||
> on `:8401` for vmselect connections (see `--vmselectAddr` flag) and on `:8482` for HTTP connections (see `-httpListenAddr` flag).
|
||
|
||
3. Start and Enable `vmstorage`:
|
||
|
||
```sh
|
||
sudo systemctl daemon-reload && systemctl enable --now vmstorage
|
||
```
|
||
|
||
4. Check that service started successfully:
|
||
|
||
```sh
|
||
sudo systemctl status vmstorage
|
||
```
|
||
|
||
5. After `vmstorage` is in `Running` state, confirm the service is healthy by visiting `http://<ip_or_hostname>:8482/-/healthy` link.
|
||
It should say "VictoriaMetrics is Healthy".
|
||
|
||
##### Installing vminsert
|
||
|
||
1. Create a Linux Service for `vminsert` by running the following command:
|
||
|
||
```sh
|
||
cat << END >/etc/systemd/system/vminsert.service
|
||
[Unit]
|
||
Description=VictoriaMetrics vminsert service
|
||
After=network.target
|
||
|
||
[Service]
|
||
Type=simple
|
||
User=victoriametrics
|
||
Group=victoriametrics
|
||
Restart=always
|
||
ExecStart=/usr/local/bin/vminsert-prod -storageNode=<list of vmstorages>
|
||
|
||
PrivateTmp=yes
|
||
NoNewPrivileges=yes
|
||
ProtectSystem=full
|
||
|
||
[Install]
|
||
WantedBy=multi-user.target
|
||
END
|
||
```
|
||
|
||
Replace `<list of vmstorages>` with addresses of previously configured `vmstorage` services.
|
||
To specify multiple addresses you can repeat the flag multiple times, or separate addresses with commas
|
||
in one flag. See more details in `-storageNode` flag description [here](https://docs.victoriametrics.com/cluster-victoriametrics/#list-of-command-line-flags-for-vminsert).
|
||
|
||
> Please note, `vminsert` service is listening on `:8480` for HTTP connections (see `-httpListenAddr` flag).
|
||
|
||
2. Start and Enable `vminsert`:
|
||
|
||
```sh
|
||
sudo systemctl daemon-reload && sudo systemctl enable --now vminsert.service
|
||
```
|
||
|
||
3. Check that service started successfully:
|
||
|
||
```sh
|
||
sudo systemctl status vminsert.service
|
||
```
|
||
|
||
4. After `vminsert` is in `Running` state, confirm the service is healthy by visiting `http://<ip_or_hostname>:8480/-/healthy` link.
|
||
It should say "VictoriaMetrics is Healthy"
|
||
|
||
##### Installing vmselect
|
||
|
||
1. Create a folder to store temporary cache:
|
||
|
||
```sh
|
||
sudo mkdir -p /var/lib/vmselect-cache && sudo chown -R victoriametrics:victoriametrics /var/lib/vmselect-cache
|
||
```
|
||
|
||
2. Add a Linux Service for `vmselect` by running
|
||
|
||
```bash
|
||
cat << END >/etc/systemd/system/vmselect.service
|
||
[Unit]
|
||
Description=VictoriaMetrics vmselect service
|
||
After=network.target
|
||
|
||
[Service]
|
||
Type=simple
|
||
User=victoriametrics
|
||
Group=victoriametrics
|
||
Restart=always
|
||
ExecStart=/usr/local/bin/vmselect-prod -storageNode=<list of vmstorages> -cacheDataPath=/var/lib/vmselect-cache
|
||
|
||
PrivateTmp=yes
|
||
NoNewPrivileges=yes
|
||
|
||
ProtectSystem=full
|
||
|
||
[Install]
|
||
WantedBy=multi-user.target
|
||
END
|
||
```
|
||
|
||
Replace `<list of vmstorages>` with addresses of previously configured `vmstorage` services.
|
||
To specify multiple addresses you can repeat the flag multiple times, or separate addresses with commas
|
||
in one flag. See more details in `-storageNode` flag description [here](https://docs.victoriametrics.com/cluster-victoriametrics/#list-of-command-line-flags-for-vminsert).
|
||
|
||
> Please note, `vmselect` service is listening on `:8481` for HTTP connections (see `-httpListenAddr` flag).
|
||
|
||
3. Start and Enable `vmselect`:
|
||
|
||
```sh
|
||
sudo systemctl daemon-reload && sudo systemctl enable --now vmselect.service
|
||
```
|
||
|
||
4. Make sure the `vmselect` service is running:
|
||
|
||
```sh
|
||
sudo systemctl status vmselect.service
|
||
```
|
||
|
||
5. After `vmselect` is in `Running` state, confirm the service is healthy by visiting `http://<ip_or_hostname>:8481/select/0/vmui` link.
|
||
It should open [vmui](https://docs.victoriametrics.com/#vmui) page.
|
||
|
||
## Write data
|
||
|
||
There are two main models in monitoring for data collection:
|
||
[push](https://docs.victoriametrics.com/keyconcepts/#push-model)
|
||
and [pull](https://docs.victoriametrics.com/keyconcepts/#pull-model).
|
||
Both are used in modern monitoring and both are supported by VictoriaMetrics.
|
||
|
||
See more details on [writing data here](https://docs.victoriametrics.com/keyconcepts/#write-data).
|
||
|
||
|
||
## Query data
|
||
|
||
VictoriaMetrics provides an
|
||
[HTTP API](https://docs.victoriametrics.com/single-server-victoriametrics/#prometheus-querying-api-usage)
|
||
for serving read queries. The API is used in various integrations such as
|
||
[Grafana](https://docs.victoriametrics.com/single-server-victoriametrics/#grafana-setup).
|
||
The same API is also used by
|
||
[VMUI](https://docs.victoriametrics.com/single-server-victoriametrics/#vmui) - graphical User Interface
|
||
for querying and visualizing metrics.
|
||
|
||
[MetricsQL](https://docs.victoriametrics.com/metricsql/) - is the query language for executing read queries
|
||
in VictoriaMetrics. MetricsQL is a [PromQL](https://prometheus.io/docs/prometheus/latest/querying/basics)
|
||
-like query language with a powerful set of functions and features for working specifically with time series data.
|
||
|
||
See more details on [querying data here](https://docs.victoriametrics.com/keyconcepts/#query-data)
|
||
|
||
|
||
## Alerting
|
||
|
||
It is not possible to physically trace all changes on graphs all the time, that is why alerting exists.
|
||
In [vmalert](https://docs.victoriametrics.com/vmalert/) it is possible to create a set of conditions
|
||
based on PromQL and MetricsQL queries that will send a notification when such conditions are met.
|
||
|
||
## Data migration
|
||
|
||
Migrating data from other TSDBs to VictoriaMetrics is as simple as importing data via any of
|
||
[supported formats](https://docs.victoriametrics.com/keyconcepts/#push-model).
|
||
|
||
The migration might get easier when using [vmctl](https://docs.victoriametrics.com/vmctl/) - VictoriaMetrics
|
||
command line tool. It supports the following databases for migration to VictoriaMetrics:
|
||
* [Prometheus using snapshot API](https://docs.victoriametrics.com/vmctl/#migrating-data-from-prometheus);
|
||
* [Thanos](https://docs.victoriametrics.com/vmctl/#migrating-data-from-thanos);
|
||
* [InfluxDB](https://docs.victoriametrics.com/vmctl/#migrating-data-from-influxdb-1x);
|
||
* [OpenTSDB](https://docs.victoriametrics.com/vmctl/#migrating-data-from-opentsdb);
|
||
* [Migrate data between VictoriaMetrics single and cluster versions](https://docs.victoriametrics.com/vmctl/#migrating-data-from-victoriametrics).
|
||
|
||
## Productionization
|
||
|
||
When going to production with VictoriaMetrics we recommend following the recommendations.
|
||
|
||
### Monitoring
|
||
|
||
Each VictoriaMetrics component emits its own metrics with various details regarding performance
|
||
and health state. Docs for the components also contain a `Monitoring` section with an explanation
|
||
of what and how should be monitored. For example,
|
||
[Single-server-VictoriaMetrics Monitoring](https://docs.victoriametrics.com/cluster-victoriametrics/#monitoring).
|
||
|
||
VictoriaMetric team prepared a list of [Grafana dashboards](https://grafana.com/orgs/victoriametrics/dashboards)
|
||
for the main components. Each dashboard contains a lot of useful information and tips. It is recommended
|
||
to have these dashboards installed and up to date.
|
||
|
||
Using the [recommended alerting rules](https://github.com/VictoriaMetrics/VictoriaMetrics/tree/master/deployment/docker#alerts)
|
||
versions would also help to identify and notify about issues with the system.
|
||
|
||
The rule of thumb is to have a separate installation of VictoriaMetrics or any other monitoring system
|
||
to monitor the production installation of VictoriaMetrics. This would make monitoring independent and
|
||
will help identify problems with the main monitoring installation.
|
||
|
||
See more details in the article [VictoriaMetrics Monitoring](https://victoriametrics.com/blog/victoriametrics-monitoring/).
|
||
|
||
### Capacity planning
|
||
|
||
See capacity planning sections in [docs](https://docs.victoriametrics.com) for
|
||
[Single-server-VictoriaMetrics](https://docs.victoriametrics.com/single-server-victoriametrics/#capacity-planning)
|
||
and [VictoriaMetrics Cluster](https://docs.victoriametrics.com/cluster-victoriametrics/#capacity-planning).
|
||
|
||
Capacity planning isn't possible without [monitoring](#monitoring), so consider configuring it first.
|
||
Understanding resource usage and performance of VictoriaMetrics also requires knowing the tech terms
|
||
[active series](https://docs.victoriametrics.com/faq/#what-is-an-active-time-series),
|
||
[churn rate](https://docs.victoriametrics.com/faq/#what-is-high-churn-rate),
|
||
[cardinality](https://docs.victoriametrics.com/faq/#what-is-high-cardinality),
|
||
[slow inserts](https://docs.victoriametrics.com/faq/#what-is-a-slow-insert).
|
||
All of them are present in [Grafana dashboards](https://grafana.com/orgs/victoriametrics/dashboards).
|
||
|
||
|
||
### Data safety
|
||
|
||
It is recommended to read [Replication and data safety](https://docs.victoriametrics.com/cluster-victoriametrics/#replication-and-data-safety),
|
||
[Why replication doesn’t save from disaster?](https://valyala.medium.com/speeding-up-backups-for-big-time-series-databases-533c1a927883)
|
||
and [backups](https://docs.victoriametrics.com/single-server-victoriametrics/#backups).
|
||
|
||
|
||
### Configuring limits
|
||
|
||
To avoid excessive resource usage or performance degradation limits must be in place:
|
||
* [Resource usage limits](https://docs.victoriametrics.com/faq/#how-to-set-a-memory-limit-for-victoriametrics-components);
|
||
* [Cardinality limiter](https://docs.victoriametrics.com/single-server-victoriametrics/#cardinality-limiter).
|
||
|
||
### Security recommendations
|
||
|
||
* [Security recommendations for single-node VictoriaMetrics](https://docs.victoriametrics.com/#security)
|
||
* [Security recommendations for cluster version of VictoriaMetrics](https://docs.victoriametrics.com/cluster-victoriametrics/#security)
