Configure prometheus server
---------------------------

.. code-block:: yaml

  prometheus:
    server:
      enabled: true
      dir:
        config: /srv/volumes/prometheus
        config_in_container: /opt/prometheus/config
      bind:
        port: 9090
        address: 0.0.0.0
      external_port: 15010
      target:
        dns:
          - name: 'pushgateway'
            domain:
            - 'tasks.prometheus_pushgateway'
            type: A
            port: 9091
          - name: 'prometheus'
            domain:
            - 'tasks.prometheus_server'
            type: A
            port: 9090
        kubernetes:
          api_ip: ${_param:kubernetes_control_address}
          ssl_dir: /opt/prometheus/config
          cert_name: kubelet-client.crt
          key_name: kubelet-client.key
        etcd:
          - host: ${_param:cluster_node01_address}
            port: ${_param:cluster_node01_port}

            port: ${_param:cluster_node02_port}
          - host: ${_param:cluster_node03_address}
            port: ${_param:cluster_node03_port}
      recording:
        - name: 'instance:fd_utilization'
          query: >-
            process_open_fds / process_max_fds
      alert:
        PrometheusTargetDown:
          if: 'up != 1'
          labels:
            severity: down
          annotations:

Configure alertmanager
----------------------

.. code-block:: yaml

        global:
          resolve_timeout: 5m
        route:
          group_by: ['alertname', 'region', 'service']
          group_wait: 60s
          group_interval: 5m
          repeat_interval: 3h
          receiver: HTTP-notification
        inhibit_rules:
          - source_match:
              severity: 'down'
            target_match:
              severity: 'critical'
            equal: ['region', 'service']
          - source_match:
              severity: 'down'
            target_match:
              severity: 'warning'
            equal: ['region', 'service']
          - source_match:
              severity: 'critical'
            target_match:
              severity: 'warning'
            equal: ['alertname', 'region', 'service']
        receivers:
          - name: 'HTTP-notification'
            webhook_configs:
              - url: http://127.0.0.1
