Prometheus: Documentation

Grafana: Documentation

Thanos. Documentation

How to change infrastructure

• New namespace will be created (by default name "monitoring")
• New 3 applications for ArgoCD (grafana, prometheus, thanos)
• New ingress and dns records will be created (thanos.domain.name, grafana.domain.name). You can disable ingress if provide additional config (grafana_conf = {ingress.enabled = false} and thanos_conf = {queryFrontend.ingress.enabled = false}
• If ingress is disabled, you can test locally by port-forwarding (example: kubectl port-forward grafana-pod 3000:3000)
• By default, thanos backend will create s3 bucket "<domain_name>-thanos and IAM policy.

Prometheus

Install the kube-prometheus, de-facto standard for monitoring.

Grafana

Install the grafana, web dashboarding system

Thanos

Install the thanos, long term storage capabilities for prometheus

Example

module "prometheus" {
  depends_on      = [module.argocd]
  source          = "github.com/provectus/sak-prometheus"
  cluster_name    = module.eks.cluster_id
  argocd          = module.argocd.state
  domains         = local.domain
  tags            = local.tags
}

Optional parameters

  namespace               = "moniroting" # Set namespace to install all charts
  thanos_enabled          = true # Enable install thanos application
  grafana_enabled         = true # Enable install prometheus application
  prometheus_enabled      = true # Enable install grafana application
  thanos_storage          = "s3" # Object storage backend.
  thanos_password         = "password" # Use as minio secret if thanos_storage = "minio"
  grafana_password        = "password" # Set grafana admin password, autogenerate and store to paramstore if empty
  grafana_google_auth     = true
  grafana_client_id       = "xxxxx"
  grafana_client_secret   = "xxxxx"
  grafana_allowed_domains = "example.com"
  thanos_conf             = {} # Additional thanos configurations
  grafana_conf            = {} # Additional grafana configurations
  prometheus_conf         = {} # Additional prometheus configurations
