Salt Prometheus formula

Power your metrics and alerting with a leading open-source monitoring solution.

Sample pillars

Configure prometheus server

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: prometheus-server.crt
        key_name: prometheus-server.key
      etcd:
        scheme: https
        ssl_dir: /opt/prometheus/config
        cert_name: prometheus-server.crt
        key_name: prometheus-server.key
        member:
          - host: ${_param:cluster_node01_address}
            port: ${_param:cluster_node01_port}
          - host: ${_param:cluster_node02_address}
            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:

Configure alertmanager

prometheus:

        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'
