How to use this module
|
|
----------------------
|
|
|
|
Add a user to MongoDB (on the primary instance) :
|
|
|
|
```
|
|
use admin
|
|
db.auth("admin", "admin-password") ## This is optional if you don't have any admin password
|
|
db.createUser({"user":"datadog", "pwd": "{{PASSWORD}}", "roles" : [ {role: 'read', db: 'admin' }, {role: 'clusterMonitor', db: 'admin'}, {role: 'read', db: 'local' }]})
|
|
```
|
|
|
|
Add a module in your Terraform project :
|
|
|
|
```
|
|
module "datadog-monitors-aws-mongodb" {
|
|
source = "git::ssh://git@bitbucket.org/morea/terraform.feature.datadog.git//databases/mongodb?ref={revision}"
|
|
|
|
message = "${module.datadog-message-alerting.alerting-message}"
|
|
environment = "${var.environment}"
|
|
|
|
}
|
|
```
|
|
|
|
Configure your Datadog agent for kubernetes with this config :
|
|
|
|
```
|
|
datadog:
|
|
confd:
|
|
mongo.yaml: |-
|
|
ad_identifiers:
|
|
- mongodb
|
|
init_config:
|
|
instances:
|
|
- server: mongodb://datadog:password@%%host%%/admin
|
|
tags:
|
|
- dd_monitoring:enabled
|
|
- dd_mongodb:enabled
|
|
- env:prod
|
|
```
|
|
|
|
|
|
Purpose
|
|
-------
|
|
|
|
Creates a DataDog monitors with the following checks :
|
|
* MongoDB Primary status
|
|
* MongoDB Secondaries status
|
|
* MongoDB replication lag
|
|
|
|
**Monitor MongoDB Primary**
|
|
|
|
Name: [environment] MongoDB Primary
|
|
|
|
This monitor will check the health of the Primary node
|
|
|
|
This monitor will trigger an alert if there's no primary or if the primary state is wrong.
|
|
|
|
|
|
**Monitor MongoDB Secondary**
|
|
|
|
Name: [environment] MongoDB Secondary
|
|
|
|
This monitor will check the health for secondaries nodes
|
|
|
|
This monitor will trigger an alert if a secondary is missing or if there's a wrong state
|
|
|
|
|
|
**Monitor MongoDB Replication lag**
|
|
|
|
Name: [environment] MongoDB Replication lag
|
|
|
|
This monitor will check the replication lag
|
|
|
|
This monitor will trigger an alert if the replication high is too high
|
|
|
|
