Configuring Watcher to Send Messages to Slack

You configure the accounts Watcher can use to communicate with Slack in your elasticsearch.yml configuration file. Each account configuration has a unique name and specifies an Incoming Webhook URL for posting messages to Slack. You can also specify message defaults, such the sender name and icon.

Before you can configure a Slack account, you need to set up an Incoming Webhook Integration through the Slack console:

To configure a Slack account in Watcher, you set the watcher.actions.slack.service property in elasticsearch.yml. You must set the url to your incoming webhook integration URL. You can also specify defaults for the notification messages. For the complete list of attributes, see Slack Account Attributes.

For example, the following snippet configures an account called notify-monitoring and sets the default sender name to Watcher.

watcher.actions.slack.service:
  account:
    monitoring:
      url: https://hooks.slack.com/services/T00000000/B00000001/XXXXXXXXXXXXXXXXXXXXXXXX
      message_defaults:
        from: Watcher

If you configure multiple Slack accounts, you either need to configure a default Slack account or specify which account the notification should be sent with in the slack action. You set default_account in watcher.actions.slack.service to specify a default account.

watcher.actions.slack.service:
  default_account: team1
  account:
    team1:
      url: https://hooks.slack.com/services/T00000000/B00000001/XXXXXXXXXXXXXXXXXXXXXXXX
      message_defaults:
        from: watcher
    team2:
      url: https://hooks.slack.com/services/T00000000/B00000002/XXXXXXXXXXXXXXXXXXXXXXXX
      message_defaults:
        from: watcher
