--- sort: 24 --- # Prometheus service discovery [vmagent](https://docs.victoriametrics.com/vmagent.html) and [single-node VictoriaMetrics](https://docs.victoriametrics.com/#how-to-scrape-prometheus-exporters-such-as-node-exporter) 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](https://azure.microsoft.com/en-us/). See [these docs](#azure_sd_configs). * `consul_sd_configs` is for discovering and scraping targets registered in [Consul](https://www.consul.io/). See [these docs](#consul_sd_configs). * `digitalocean_sd_configs` is for discovering and scraping targerts registered in [DigitalOcean](https://www.digitalocean.com/). See [these docs](#digitalocean_sd_configs). * `dns_sd_configs` is for discovering and scraping targets from [DNS](https://it.wikipedia.org/wiki/Domain_Name_System) records (SRV, A and AAAA). See [these docs](#dns_sd_configs). * `docker_sd_configs` is for discovering and scraping Docker targets. See [these docs](#docker_sd_configs). * `dockerswarm_sd_configs` is for discovering and scraping Docker Swarm targets. See [dockerswarm_sd_config](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#dockerswarm_sd_config). * `ec2_sd_configs` is for discovering and scraping Amazon EC2 targets. See [ec2_sd_config](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#ec2_sd_config). `vmagent` doesn't support the `profile` config param yet. * `eureka_sd_configs` is for discovering and scraping targets registered in [Netflix Eureka](https://github.com/Netflix/eureka). See [eureka_sd_config](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#eureka_sd_config). * `file_sd_configs` is for scraping targets defined in external files (aka file-based service discovery). See [these docs](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#file_sd_config). * `gce_sd_configs` is for discovering and scraping Google Compute Engine (GCE) targets. See [gce_sd_config](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#gce_sd_config). `vmagent` provides the following additional functionality for `gce_sd_config`: * if `project` arg is missing then `vmagent` uses the project for the instance where it runs; * if `zone` arg is missing then `vmagent` uses the zone for the instance where it runs; * if `zone` arg equals to `"*"`, then `vmagent` discovers all the zones for the given project; * `zone` may contain a list of zones, i.e. `zone: [us-east1-a, us-east1-b]`. * `http_sd_configs` is for discovering and scraping targerts provided by external http-based service discovery. See [http_sd_config](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#http_sd_config). * `kubernetes_sd_configs` is for discovering and scraping Kubernetes (K8S) targets. See [kubernetes_sd_config](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#kubernetes_sd_config). * `openstack_sd_configs` is for discovering and scraping OpenStack targets. See [openstack_sd_config](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#openstack_sd_config). [OpenStack identity API v3](https://docs.openstack.org/api-ref/identity/v3/) is supported only. * `static_configs` is for scraping statically defined targets. See [these docs](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#static_config). * `yandexcloud_sd_configs` is for discoverying and scraping [Yandex Cloud](https://cloud.yandex.com/en/) targets. See [these docs](#yandexcloud_sd_configs). 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](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 configurations allow retrieving scrape targets from [Microsoft Azure](https://azure.microsoft.com/en-us/) VMs. The following meta labels are available on targets during [relabeling](https://docs.victoriametrics.com/vmagent.html#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_tag_`: each tag value of the machine * `__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_subscription_id`: the subscription ID * `__meta_azure_tenant_id`: the tenant ID 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.
