Configuration

Asset registration

Assets are the best way to make use of this handler. If you're not using an asset, please consider doing so! If you're using sensuctl 5.13 or later, you can use the following command to add the asset:

sensuctl asset add sensu/sensu-chef-handler

If you're using an earlier version of sensuctl, you can download the asset
definition from this project's Bonsai Asset Index
page
.

Handler definition

Create the handler using the following handler definition:

---
api_version: core/v2
type: Handler
metadata:
  namespace: default
  name: sensu-chef-handler
spec:
  type: pipe
  command: sensu-chef-handler
  timeout: 10
  env_vars:
  - CHEF_ENDPOINT=https://api.chef.io/organizations/replace-me
  - CHEF_CLIENT_NAME=your-chef-client
  - CHEF_CLIENT_KEY_PATH=/path/to/chef/client.pem
  - SENSU_API_URL=https://sensu-backend-url:8080
  - SENSU_API_KEY=sensu-api-key-here
  filters:
  - is_incident
  runtime_assets:
  - sensu/sensu-chef-handler

and then add the handler to the keepalive handler set:

---
api_version: core/v2
type: Handler
metadata:
  name: keepalive
  namespace: default
spec:
  handlers:
  - sensu-chef-handler
  type: set

Check definition

No check definition is needed. This handler will only trigger on keepalive
events after it is added to the keepalive handler set.
