AWS RDS Instance DataDog monitors
|
||||
=================================
|
||||
|
||||
How to use this module
|
||||
----------------------
|
||||
|
||||
```
|
||||
module "datadog-monitors-aws-rds" {
|
||||
source = "git::ssh://git@bitbucket.org/morea/terraform.feature.datadog.git//cloud/aws/rds?ref={revision}"
|
||||
|
||||
message = "${module.datadog-message-alerting.alerting-message}"
|
||||
environment = "${var.environment}"
|
||||
}
|
||||
```
|
||||
|
||||
Purpose
|
||||
-------
|
||||
Creates a DataDog monitors with the following checks :
|
||||
|
||||
* CPU High
|
||||
* Free disk space low
|
||||
|
||||
Inputs
|
||||

|
||||
|------|-------------|:----:|:-----:|:-----:|
|
||||
| cpu_threshold_critical | CPU usage in percent (critical threshold) | string | `90` | no |
|
||||
| cpu_threshold_warning | CPU usage in percent (warning threshold) | string | `80` | no |
|
||||
| diskspace_threshold_critical | Disk free space in percent (critical threshold) | string | `10` | no |
|
||||
| diskspace_threshold_warning | Disk free space in percent (warning threshold) | string | `20` | no |
|
||||
| environment | Architecture Environment | string | - | yes |
|
||||
| evaluation_delay | Delay in seconds for the metric evaluation | string | `600` | no |
|
||||
| filter_tags_custom | Tags used for custom filtering when filter_tags_use_defaults is false | string | `*` | no |
|
||||
| filter_tags_use_defaults | Use default filter tags convention | string | `true` | no |
|
||||
| message | Message sent when an alert is triggered | string | - | yes |
|
||||
| notify_no_data | Enable 'No Data' alert | string | `true` | no |
|
||||
| renotify_interval | The number of minutes after the last notification before a monitor will re-notify on the current status | string | `60` | no |
