Prometheus service discovery

vmagent and single-node VictoriaMetrics supports the following Prometheus-compatible service discovery options for Prometheus-compatible scrape targets in the file pointed by -promscrape.config command-line flag.

  • azure_sd_configs is for scraping the targets registered in Azure Cloud. See these docs.
  • consul_sd_configs is for discovering and scraping targets registered in Consul. See these docs.
  • digitalocean_sd_configs is for discovering and scraping targerts registered in DigitalOcean. See these docs.
  • dns_sd_configs is for discovering and scraping targets from DNS records (SRV, A and AAAA). See these docs.
  • docker_sd_configs is for discovering and scraping Docker targets. See these docs.
  • dockerswarm_sd_configs is for discovering and scraping Docker Swarm targets. See these docs.
  • ec2_sd_configs is for discovering and scraping Amazon EC2 targets. See these docs.
  • eureka_sd_configs is for discovering and scraping targets registered in Netflix Eureka. See these docs.
  • file_sd_configs is for scraping targets defined in external files (aka file-based service discovery). See these docs.
  • gce_sd_configs is for discovering and scraping Google Compute Engine targets. See these docs.
  • http_sd_configs is for discovering and scraping targerts provided by external http-based service discovery. See these docs.
  • kubernetes_sd_configs is for discovering and scraping Kubernetes (K8S) targets. See kubernetes_sd_config.
  • openstack_sd_configs is for discovering and scraping OpenStack targets. See openstack_sd_config. OpenStack identity API v3 is supported only.
  • static_configs is for scraping statically defined targets. See these docs.
  • yandexcloud_sd_configs is for discoverying and scraping Yandex Cloud targets. See these docs.

Note that the refresh_interval option isn't supported 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 or victoria-metrics -help in order to see default values for the -promscrape.*CheckInterval flags.

Please file feature requests to our issue tracker if you need other service discovery mechanisms to be supported by VictoriaMetrics and vmagent.

  • YAML:

    - targets: ["<host>", ... ]
      labels:

    # tag_separator is an optional separator for tags in `__meta_gce_tags` label.
    # By default "," is used.
    # tag_separator: "..."

Credentials are discovered by looking in the following places, preferring the first location found:

  1. a JSON file specified by the GOOGLE_APPLICATION_CREDENTIALS environment variable
  2. a JSON file in the well-known path $HOME/.config/gcloud/application_default_credentials.json
  3. fetched from the GCE metadata server

When running within GCE, the service account associated with the instance it is running on should have at least read-only permissions to the compute resources. If running outside of GCE make sure to create an appropriate service account and place the credential file in one of the expected locations.

http_sd_configs

HTTP-based service discovery fetches targets from the specified url. The service at url must return JSON response in the following format:

[
  {
    "targets": [ "<host>", ... ],
    "labels": {
      "<labelname>": "<labelvalue>",
      ...
    }
  },
  ...
]

The endpoint is queried periodically with the refresh interval specified in -promscrape.httpSDCheckInterval command-line flag. Discovery errors are tracked in promscrape_discovery_http_errors_total metric.

The following meta labels are available on targets during relabeling:

  • __meta_url: the URL from which the target was extracted

Configuration example:

scrape_configs:
- job_name: http
  http_sd_configs:
    # url must contain the URL from which the targets are fetched.
  - url: "http://..."

    # Additional HTTP API client options can be specified here.
    # See https://docs.victoriametrics.com/sd_configs.html#http-api-client-options

yandexcloud_sd_configs

Yandex Cloud SD configurations allow retrieving scrape targets from accessible folders.

The following meta labels are available on targets during relabeling:

  • __meta_yandexcloud_instance_name: the name of instance
  • __meta_yandexcloud_instance_id: the id of instance
  • __meta_yandexcloud_instance_fqdn: generated FQDN for instance
  • __meta_yandexcloud_instance_status: the status of instance
  • __meta_yandexcloud_instance_platform_id: instance platform ID (i.e. "standard-v3")
  • __meta_yandexcloud_instance_resources_cores: instance vCPU cores
  • __meta_yandexcloud_instance_resources_core_fraction: instance core fraction
  • __meta_yandexcloud_instance_resources_memory: instance memory
  • __meta_yandexcloud_folder_id: instance folder ID
  • __meta_yandexcloud_instance_label_<label name>: each label from instance
  • __meta_yandexcloud_instance_private_ip_<interface index>: private IP of network interface
  • __meta_yandexcloud_instance_public_ip_<interface index>: public (NAT) IP of network interface
  • __meta_yandexcloud_instance_private_dns_<record number>: if configured DNS records for private IP
  • __meta_yandexcloud_instance_public_dns_<record number>: if configured DNS records for public IP

Configuration example:

scrape_configs:
- job_name: yandexcloud
  yandexcloud_sd_configs:
    # service is a mandatory option for yandexcloud service discovery
    # currently only "compute" service is supported
  - service: compute

    # api_endpoint is an optional API endpoint for service discovery
    # The https://api.cloud.yandex.net endpoint is used by default.
    # api_endpoint: "https://api.cloud.yandex.net"

    # yandex_passport_oauth_token is an optional OAuth token
    # for querying yandexcloud API. See https://cloud.yandex.com/en-ru/docs/iam/concepts/authorization/oauth-token
    # yandex_passport_oauth_token: "..."

    # tls_config is an optional tls config.
    # See https://prometheus.io/docs/prometheus/latest/configuration/configuration/#tls_config
    # tls_config:

Yandex Cloud SD support both user OAuth token and instance service account if yandex_passport_oauth_token is omitted:

scrape_configs:
- job_name: YC_with_oauth
  yandexcloud_sd_configs:
  - service: compute
    yandex_passport_oauth_token: "AQAAAAAsfasah<...>7E10SaotuL0"
  relabel_configs:
  - source_labels: [__meta_yandexcloud_instance_public_ip_0]
    target_label: __address__
    replacement: "$1:9100"

- job_name: YC_with_Instance_service_account
  yandexcloud_sd_configs:
  - service: compute
  relabel_configs:
  - source_labels: [__meta_yandexcloud_instance_private_ip_0]
    target_label: __address__
    replacement: "$1:9100"
