DATABASE REDIS DataDog monitors

How to use this module

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

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

Purpose

Creates DataDog monitors with the following checks:

• Redis blocked clients
• Redis does not respond
• Redis evicted keys
• Redis expired keys
• Redis hitrate
• Redis keyspace seems full (no changes since ${var.keyspace_timeframe})
• Redis latency
• Redis memory fragmented
• Redis memory used
• Redis rejected connections
