Configure Metrics

Pomerium Enterprise uses Prometheus as a metrics collection back-end. You can configure Pomerium and the Console to talk to an existing Prometheus server, or configure the embedded Prometheus backend. This guide assumes you're running both Pomerium and Pomerium Enterprise on localhost 127.0.0.1.

tip

For production deployments, we suggest using a dedicated Prometheus instance.

Prepare Pomerium​

  1. In the Pomerium pomerium-config.yaml, define the metrics_address key to a network interface and/or port. For example:

    pomerium-config.yaml
    metrics_address: 127.0.0.1:9091

    The example above has Pomerium providing metrics at port 9999 on an IP address reachable by the Pomerium Console service.

    If you're running Pomerium Enterprise in a distributed environment where the IP address is not known at the time of deployment, you can use the resolvable FQDN of the Pomerium host (pomerium0.internal.example.com, for example), or override this key with the environment variable METRICS_ADDRESS. We do not recommend exposing this endpoint to public traffic as it can contain potentially sensitive information.

  2. In the Pomerium Enterprise pomerium-enterprise-config.yaml, define the metrics_addr key to a network interface and/or port. For example:

    config.yaml
    metrics_addr: 127.0.0.1:9092

External Prometheus​

  1. Add the listener to your Prometheus configuration, usually via prometheus.yml:

    - job_name: 'Pomerium'
       scrape_interval: 30s
       scrape_timeout: 5s
       static_configs:
          - targets: ['127.0.0.1:9901']
    - job_name: 'Pomerium Enterprise'
       scrape_interval: 30s
       scrape_timeout: 5s
       static_configs:
          - targets: ['127.0.0.1:9902']

  2. Reload the Prometheus configuration:

    curl -i -XPOST path.to.prometheus:port/-/reload

  3. In the Pomerium Enterprise config.yaml file, define the prometheus_url key to point to your Prometheus instance(s):

    prometheus_url: http://192.168.122.50:9090

  4. Restart the Pomerium and Pomerium Enterprise services. You should now see route traffic and External Data Source monitoring data in the Enterprise Console:

    Traffic Data in Pomerium Enterprise External Data Source in Pomerium Enterprise

Embedded Prometheus​

To take advantage of Prometheus embedded in Pomerium Enterprise, edit Pomerium Console's config file:

config.yaml
prometheus_data_dir: /var/lib/pomerium-console/tsdb

The directory path can be any location that the pomerium system user can write to. The example above uses the default location created by the OS packages.
