To set up Kapacitor and Chronograf to send alert messages to HipChat, users need their HipChat subdomain name, room name, and API access token. The `enabled` setting in the Kapacitor configuration file should be set to true, with the `url` setting set to the HipChat subdomain URL. In the TICKscript, the `.hipChat()` attribute should be included, along with the room and token attributes. Chronograf offers a user interface for working with Kapacitor, allowing users to easily create alert rules and send alert messages to event handlers like HipChat. To configure Chronograf, users need to select HipChat from the dropdown menu, enter their subdomain, room, and API access token, and click the Save button.
