module "datadog-monitors-caas-kubernetes-velero" {
  source      = "claranet/monitors/datadog//caas/kubernetes/velero"
  version     = "{revision}"

  environment = var.environment
  message     = module.datadog-message-alerting.alerting-message
}

Purpose

Creates DataDog monitors with the following checks:

How to configure Datadog agent for these monitors ?

You can configure Datadog agent by autodiscovery pod annotations or by configuration file.

Configuration by autodiscovery pod annotations

Add these annotations to Velero pods:

podAnnotations: {
  "ad.datadoghq.com/velero.check_names": '["openmetrics"]',
  "ad.datadoghq.com/velero.init_configs": '[{}]',
  "ad.datadoghq.com/velero.instances": '[{"prometheus_url": "http://%%host%%:8085/metrics", "namespace": "velero", "metrics": ["velero*"]}]'
}

Configuration by configuration file

Example of openmetrics.d/conf.yaml:

init_config:

instances:

    ## @param prometheus_url - string - required
    ## The URL where your application metrics are exposed by Prometheus.
    #
  - prometheus_url: http://velero.velero.svc.cluster.local:8085/metrics

    ## @param namespace - string - required
    ## The namespace to be prepended to all metrics.
    #
    namespace: "velero"

    ## @param metrics - list of strings - required
    ## List of metrics to be fetched from the prometheus endpoint, if there's a
    ## value it'll be renamed. This list should contain at least one metric
    #
    metrics:
      - velero*

How to monitor multiple schedule witch have different frequencies ?

If you have multiple Velero schedules with different frequencies, you must duplicate this module and disable common monitors in the others instance of module.

module "datadog-monitors-caas-kubernetes-velero" {
  source = "claranet/monitors/datadog//caas/kubernetes/velero"
  version = "{revision}"

  environment = var.environment
  message     = module.datadog-message-alerting.alerting-message

  velero_backup_failure_enabled          = false
  velero_backup_partial_failure_enabled  = false
  velero_backup_deletion_failure_enabled = false
  velero_volume_snapshot_failure_enabled = false
