DATABASE ELASTICSEARCH DataDog monitors

How to use this module

module "datadog-monitors-database-elasticsearch" {
  source = "git::ssh://git@git.fr.clara.net/claranet/pt-monitoring/projects/datadog/terraform/monitors.git//database/elasticsearch?ref={revision}"

  environment = "${var.environment}"
  message     = "${module.datadog-message-alerting.alerting-message}"
}

Purpose

Creates DataDog monitors with the following checks:

  • Elasticsearch average index flushing to disk latency
  • Elasticsearch change alert on the number of currently active queries
  • Elasticsearch change alert on the number of request cache evictions
  • ElasticSearch Cluster has unassigned shards
  • ElasticSearch does not respond
  • Elasticsearch JVM memory Old usage
  • Elasticsearch average Old-generation garbage collections latency
  • Elasticsearch change alert on the average time spent by tasks in the queue
  • Elasticsearch change alert on the number of search fetches currently running
  • ElasticSearch Cluster status not green
  • ElasticSearch free space < 10%
  • Elasticsearch number of current open HTTP connections anomaly detected
