How to use this module
|
|
----------------------
|
|
|
|
```
|
|
module "datadog-monitors-aws-elasticache-redis" {
|
|
source = "git::ssh://git@bitbucket.org/morea/terraform.feature.datadog.git//cloud/aws/elasticache/memcached?ref={revision}"
|
|
|
|
message = "${module.datadog-message-alerting.alerting-message}"
|
|
environment = "${var.environment}"
|
|
}
|
|
|
|
```
|
|
|
|
Purpose
|
|
-------
|
|
Creates DataDog monitors with the following checks :
|
|
|
|
Memcached specific:
|
|
|
|
* Get Hit
|
|
* CPU High
|
|
|
|
Elasticache common:
|
|
|
|
* Eviction
|
|
* Eviction growing
|
|
* Swap
|
|
* Max connections
|
|
* No connection
|
|
* Free Memory
|
|
