## Sensu::Extensions::CheckDependencies
This filter extension provides the Sensu Core built-in filter `check_dependencies`.
This filter matches events when an event already exists, enabling the user to
reduce notification noise and only be notified for the “root cause” of a given
failure. Check dependencies can be defined in the check definition, using
dependencies, an array of checks (e.g. `check_app`), Sensu client/check pairs
(e.g. `db-01/check_mysql`), or a subscription/check pair
(e.g. `subscription:mysql/check_mysql`).

### Installation
This extension requires Sensu version >= 0.26 and is provided as a built-in
filter in Sensu >= 0.29.
To manually install this extension on a Sensu server machine:
```
$ sudo sensu-install -e check-dependencies:1.1.0
```
Edit `/etc/sensu/conf.d/extensions.json` to load it:
```
{
"extensions": {
"check-dependencies": {
"version": "1.1.0"
}
}
}
```
### Example Check/Handler Configuration
Specify a dependency on the `mysql` check:
``` javascript
{
"checks": {
"web_application_api": {
"command": "check-http.rb -u https://localhost:8080/api/v1/health",
"subscribers": [
"web_application"
],
"interval": 20,
"dependencies": [
"mysql"
]
}
}
}
```
... or specify a dependency on another client's `mysql` check:
``` javascript
{
"checks": {
"web_application_api": {
"command": "check-http.rb -u https://localhost:8080/api/v1/health",
"subscribers": [
"web_application"
],
"interval": 20,
"dependencies": [
"db-01/mysql"
]
}
}
}
```
... or specify a dependency on any `mysql` check in the `mysql_nodes`
subscription:
``` javascript
{
"checks": {
"web_application_api": {
"command": "check-http.rb -u https://localhost:8080/api/v1/health",
"subscribers": [
"web_application"
],
"interval": 20,
"dependencies": [
"subscription:mysql_nodes/mysql"
]
}
}
}
```
Apply the `check_dependencies` filter to one or more handlers:
``` javascript
{
"handlers": {
"custom_mailer": {
"type": "pipe",
"command": "custom_mailer.rb",
"filters": ["check_dependencies"]
}
}
}
```
