Please file feature requests to [our issue tracker](https://github.com/VictoriaMetrics/VictoriaMetrics/issues) if you need other service discovery mechanisms to be supported by VictoriaMetrics and `vmagent`. ## azure_sd_configs Azure SD configuration discovers scrape targets from [Microsoft Azure](https://azure.microsoft.com/en-us/) VMs. Configuration example: ```yaml scrape_configs: - job_name: azure azure_sd_configs: # subscription_id is a mandatory subscription ID. # - subscription_id: "..." # environment is an optional Azure environment. By default "AzurePublicCloud" is used. # # environment: "..." # authentication_method is an optional authentication method, either OAuth or ManagedIdentity. # See https://docs.microsoft.com/en-us/azure/active-directory/managed-identities-azure-resources/overview # By default OAuth is used. # # authentication_method: "..." # tenant_id is an optional tenant ID. Only required with authentication_method OAuth. # # tenant_id: "..." # client_id is an optional client ID.

Only required with authentication_method OAuth. # # client_secret: "..." # resource_group is an optional resource group name. Limits discovery to this resource group. # # resource_group: "..." # port is an optional port to scrape metrics from. # Port 80 is used by default. # # port: ... # Additional HTTP API client options can be specified here. # See https://docs.victoriametrics.com/sd_configs/#http-api-client-options ``` Each discovered target has an [`__address__`](https://docs.victoriametrics.com/relabeling/#how-to-modify-scrape-urls-in-targets) label set to `:`, where `` is the machine's private IP and the `` is the `port` option specified in the `azure_sd_configs`. The following meta labels are available on discovered targets during [relabeling](https://docs.victoriametrics.com/vmagent/#relabeling): * `__meta_azure_machine_id`: the machine ID * `__meta_azure_machine_location`: the location the machine runs in * `__meta_azure_machine_name`: the machine name * `__meta_azure_machine_computer_name`: the machine computer name * `__meta_azure_machine_os_type`: the machine operating system * `__meta_azure_machine_private_ip`: the machine's private IP * `__meta_azure_machine_public_ip`: the machine's public IP if it exists * `__meta_azure_machine_resource_group`: the machine's resource group * `__meta_azure_machine_scale_set`: the name of the scale set which the vm is part of (this value is only set if you are using a scale set) * `__meta_azure_machine_size`: the machine size * `__meta_azure_machine_tag_`: each tag value of the machine * `__meta_azure_subscription_id`: the subscription ID * `__meta_azure_tenant_id`: the tenant ID The list of discovered Azure targets is refreshed at the interval, which can be configured via `-promscrape.azureSDCheckInterval` command-line flag. ## consul_sd_configs Consul SD configuration allows retrieving scrape targets from [Consul's Catalog API](https://www.consul.io/api-docs/catalog). Configuration example: ```yaml scrape_configs: - job_name: consul consul_sd_configs: # server is an optional Consul server to connect to. By default, localhost:8500 is used # - server: "localhost:8500" # token is an optional Consul API token. # If the token isn't specified, then it is read from a file pointed by CONSUL_HTTP_TOKEN_FILE # environment var or from the CONSUL_HTTP_TOKEN environment var. # # token: "..." # datacenter is an optional Consul API datacenter. # If the datacenter isn't specified, then it is read from Consul server. # See https://www.consul.io/api-docs/agent#read-configuration # # datacenter: "..." # namespace is an optional Consul namespace. # See https://developer.hashicorp.com/consul/docs/enterprise/namespaces # If the namespace isn't specified, then it is read from CONSUL_NAMESPACE environment var. # # namespace: "..." # partition is an optional Consul partition. # See https://developer.hashicorp.com/consul/docs/enterprise/admin-partitions # If partition isn't specified, then the default partition is used. # # partition: "..." # scheme is an optional scheme (http or https) to use for connecting to Consul server. # By default, http scheme is used. # # scheme: "..." # services is an optional list of services for which targets are retrieved. # If omitted, all services are scraped. # See https://www.consul.io/api-docs/catalog#list-nodes-for-service . # # services: ["...", "..."] # tags is an optional list of tags used to filter nodes for a given service. # Services must contain all tags in the list. # Deprecated: use filter instead with ServiceTags selector. # # tags: ["...", "..."] # node_meta is an optional node metadata key/value pairs to filter nodes for a given service. # Deprecated: use filter instead with NodeMeta selector. # # node_meta: # "...": "..." # tag_separator is an optional string by which Consul tags are joined into the __meta_consul_tags label. # By default, "," is used as a tag separator. # Individual tags are also available via __meta_consul_tag_ labels - see below. # # tag_separator: "..." # filter is an optional filter for service discovery. # Replaces tags and node_meta options. # Consul supports it since 1.14 version. # See the list of supported filters at https://developer.hashicorp.com/consul/api-docs/catalog#filtering-1 # See filter examples at https://developer.hashicorp.com/consul/api-docs/features/filtering # # filter: "..." # allow_stale is an optional config, which allows stale Consul results. # See https://developer.hashicorp.com/consul/api-docs/features/consistency # Reduce load on Consul if set to true. By default, it is set to true. # # allow_stale: ... # Additional HTTP API client options can be specified here. # See https://docs.victoriametrics.com/sd_configs/#http-api-client-options ``` Each discovered target has an [`__address__`](https://docs.victoriametrics.com/relabeling/#how-to-modify-scrape-urls-in-targets) label set to `:`, where `` is the service address. If the service address is empty, then the node address is used instead. The `` is the service port. The following meta labels are available on discovered targets during [relabeling](https://docs.victoriametrics.com/vmagent/#relabeling): * `__meta_consul_address`: the address of the target * `__meta_consul_dc`: the datacenter name for the target * `__meta_consul_health`: the health status of the service * `__meta_consul_metadata_`: each node metadata key value of the target * `__meta_consul_namespace`: namespace of the service - see [namespace docs](https://developer.hashicorp.com/consul/docs/enterprise/namespaces) * `__meta_consul_node`: the node name defined for the target * `__meta_consul_partition`: partition of the service - see [partition docs](https://developer.hashicorp.com/consul/docs/enterprise/admin-partitions) * `__meta_consul_service_address`: the service address of the target * `__meta_consul_service_id`: the service ID of the target * `__meta_consul_service_metadata_`: each service metadata key value of the target * `__meta_consul_service_port`: the service port of the target * `__meta_consul_service`: the name of the service the target belongs to * `__meta_consul_tagged_address_`: each node tagged address key value of the target * `__meta_consul_tag_`: the value for the given tag of the target * `__meta_consul_tagpresent_`: "true" for every tag of the target * `__meta_consul_tags`: the list of tags of the target joined by the `tag_separator` The list of discovered Consul targets is refreshed at the interval, which can be configured via `-promscrape.consulSDCheckInterval` command-line flag. If you have performance issues with `consul_sd_configs` on a large cluster, then consider using [consulagent_sd_configs](#consulagent_sd_configs) instead. ## consulagent_sd_configs Consul Agent SD configuration allows retrieving scrape targets from [Consul Agent API](https://developer.hashicorp.com/consul/api-docs/agent/service). When using the Agent API, only services registered in the locally running Consul Agent are discovered. It is suitable for huge clusters for which using the [Catalog API](https://developer.hashicorp.com/consul/api-docs/catalog#list-services) would be too slow or resource intensive, in other cases it is recommended to use [consul_sd_configs](#consul_sd_configs). Configuration example: ```yaml scrape_configs: - job_name: consulagent consulagent_sd_configs: # server is an optional Consul Agent to connect to. By default, localhost:8500 is used # - server: "localhost:8500" # token is an optional Consul API token. # If the token isn't specified, then it is read from a file pointed by CONSUL_HTTP_TOKEN_FILE # environment var or from the CONSUL_HTTP_TOKEN environment var. # # token: "..." # datacenter is an optional Consul API datacenter. # If the datacenter isn't specified, then it is read from Consul server. # See https://www.consul.io/api-docs/agent#read-configuration # # datacenter: "..." # namespace is an optional Consul namespace. # See https://developer.hashicorp.com/consul/docs/enterprise/namespaces # If the namespace isn't specified, then it is read from CONSUL_NAMESPACE environment var. # # namespace: "..." # scheme is an optional scheme (http or https) to use for connecting to Consul server. # By default, http scheme is used. # # scheme: "..." # services is an optional list of services for which targets are retrieved. # If omitted, all services are scraped. # See https://www.consul.io/api-docs/catalog#list-nodes-for-service . # # services: ["...", "..."] # tag_separator is an optional string by which Consul tags are joined into the __meta_consul_tags label. # By default, "," is used as a tag separator. # Individual tags are also available via __meta_consul_tag_ labels - see below. # # tag_separator: "..." # filter is optional filter for service nodes discovery request. # Replaces tags and node_metadata options. # consul supports it since 1.14 version # list of supported filters https://developer.hashicorp.com/consul/api-docs/catalog#filtering-1 # syntax examples https://developer.hashicorp.com/consul/api-docs/features/filtering # # filter: "..." # Additional HTTP API client options can be specified here. # See https://docs.victoriametrics.com/sd_configs/#http-api-client-options ``` Each discovered target has an [`__address__`](https://docs.victoriametrics.com/relabeling/#how-to-modify-scrape-urls-in-targets) label set to `:`, where `` is the service address. If the service address is empty, then the node address is used instead. The `` is the service port. The following meta labels are available on discovered targets during [relabeling](https://docs.victoriametrics.com/vmagent/#relabeling): * `__meta_consulagent_address`: the address of the target * `__meta_consulagent_dc`: the datacenter name for the target * `__meta_consulagent_health`: the health status of the service * `__meta_consulagent_metadata_`: each node metadata key value of the target * `__meta_consulagent_namespace`: namespace of the service - see [namespace docs](https://developer.hashicorp.com/consul/docs/enterprise/namespaces) * `__meta_consulagent_node`: the node name defined for the target * `__meta_consulagent_service_address`: the service address of the target * `__meta_consulagent_service_id`: the service ID of the target * `__meta_consulagent_service_metadata_`: each service metadata key value of the target * `__meta_consulagent_service_port`: the service port of the target * `__meta_consulagent_service`: the name of the service the target belongs to * `__meta_consulagent_tagged_address_`: each node tagged address key value of the target * `__meta_consulagent_tag_`: the value for the given tag of the target * `__meta_consulagent_tagpresent_`: "true" for every tag of the target * `__meta_consulagent_tags`: the list of tags of the target joined by the `tag_separator` The list of discovered Consul Agent targets is refreshed at the interval, which can be configured via `-promscrape.consulagentSDCheckInterval` command-line flag. ## digitalocean_sd_configs DigitalOcean SD configuration allows retrieving scrape targets from [DigitalOcean's Droplets API](https://docs.digitalocean.com/reference/api/api-reference/#tag/Droplets). Configuration example: ```yaml scrape_configs: - job_name: digitalocean digitalocean_sd_configs: # server is an optional DigitalOcean API server to query. # By default, https://api.digitalocean.com is used. # - server: "https://api.digitalocean.com" # port is an optional port to scrape metrics from.

The following meta labels are available on discovered targets during [relabeling](https://docs.victoriametrics.com/vmagent/#relabeling): * `__meta_digitalocean_droplet_id`: the id of the droplet * `__meta_digitalocean_droplet_name`: the name of the droplet * `__meta_digitalocean_image`: the slug of the droplet's image * `__meta_digitalocean_image_name`: the display name of the droplet's image * `__meta_digitalocean_private_ipv4`: the private IPv4 of the droplet * `__meta_digitalocean_public_ipv4`: the public IPv4 of the droplet * `__meta_digitalocean_public_ipv6`: the public IPv6 of the droplet * `__meta_digitalocean_region`: the region of the droplet * `__meta_digitalocean_size`: the size of the droplet * `__meta_digitalocean_status`: the status of the droplet * `__meta_digitalocean_features`: the comma-separated list of features of the droplet * `__meta_digitalocean_tags`: the comma-separated list of tags of the droplet * `__meta_digitalocean_vpc`: the id of the droplet's VPC The list of discovered DigitalOcean targets is refreshed at the interval, which can be configured via `-promscrape.digitaloceanSDCheckInterval` command-line flag. ## dns_sd_configs DNS-based service discovery allows retrieving scrape targets from the specified DNS domain names. These specified names are periodically queried to discover a list of targets with the interval configured via `-promscrape.dnsSDCheckInterval` command-line flag. Configuration example: ```yaml scrape_configs: - job_name: dns dns_sd_configs: # names must contain a list of DNS names to query. # - names: ["...", "..."] # type is an optional type of DNS query to perform. # Supported values are: SRV, A, AAAA or MX. # By default, SRV is used. # # type: ... # port is a port number to use if the query type is not SRV. # # port: ... ``` Each discovered target has an [`__address__`](https://docs.victoriametrics.com/relabeling/#how-to-modify-scrape-urls-in-targets) label set to the `:`, where `` is the discovered DNS address, while `` is either the discovered port for SRV records or the port specified in the `dns_sd_config`. The following meta labels are available on discovered targets during [relabeling](https://docs.victoriametrics.com/vmagent/#relabeling): * `__meta_dns_name`: the record name that produced the discovered target. * `__meta_dns_srv_record_target`: the target field of the SRV record * `__meta_dns_srv_record_port`: the port field of the SRV record * `__meta_dns_mx_record_target`: the target field of the MX record. The list of discovered DNS targets is refreshed at the interval, which can be configured via `-promscrape.dnsSDCheckInterval` command-line flag. ## docker_sd_configs Docker SD configuration allows retrieving scrape targets from [Docker Engine](https://docs.docker.com/engine/) hosts. Configuration example: ```yaml scrape_configs: - job_name: docker docker_sd_configs: # host must contain the address of the Docker daemon. # - host: "..." # port is an optional port to scrape metrics from. # By default, port 80 is used. # # port: ... # host_networking_host is an optional host to use if the container is in host networking mode. # By default, localhost is used. # # host_networking_host: "..." # filters is an optional filters to limit the discovery process to a subset of available resources. # See https://docs.docker.com/engine/api/v1.40/#operation/ContainerList # # filters: # - name: "..." # values: ["...", "..."] # Additional HTTP API client options can be specified here. # See https://docs.victoriametrics.com/sd_configs/#http-api-client-options ``` Each discovered target has an [`__address__`](https://docs.victoriametrics.com/relabeling/#how-to-modify-scrape-urls-in-targets) label set to `:`, where `` is the exposed ip address of the docker container, while the `` is either the exposed port of the docker container or the port specified in the `docker_sd_configs` if the docker container has no exposed ports.
