Présentation

Rassemblez des métriques à partir de vos clusters Nomad pour :

  • Visualiser et surveiller les performances de vos clusters
  • Envoyer des alertes sur la disponibilité et la santé des clusters

Les monitors recommandés vous permettent de recevoir une notification lorsque différents événements Nomad se produisent.

Configuration

Installation

Nomad transmet des métriques à Datadog via DogStatsD. Pour activer l’intégration Nomad, installez l’Agent Datadog sur chaque client et chaque host du serveur.

Configuration

Une fois l’installation de l’Agent Datadog effectuée, ajoutez un bloc télémétrie à la configuration Nomad pour vos clients et serveurs :

telemetry {
  publish_allocation_metrics = true
  publish_node_metrics       = true
  datadog_address = "localhost:8125"
  disable_hostname = true
  collection_interval = "10s"
}

Rechargez ou redémarrez ensuite l’agent Nomad sur chaque host. Les métriques Nomad devraient alors commencer à être envoyées à votre compte Datadog.
