Sensu Integration Guide – VictorOps

Requirements

VictorOps Version Required: Getting Started, Essentials, or Full-Stack

The Sensu integration uses a dedicated Sensu endpoint key to send alerts into the VictorOps timeline. Below are the necessary parts and some relevant Sensu docs.

In VictorOps

Navigate to your VO instance’s Integrations page by clicking Integrations. From the resulting list of integrations, select the Sensu integration.

From here, click the ‘Enable Integration’ button to have a Sensu API Endpoint generated for you. Copy this Service API Endpoint to your clipboard, ensuring that your replace the ‘$routing_key’ piece at the end of the API Endpoint to a valid routing_key. Alerts from this configuration will route through this key. For more information on routing_keys, please see this Knowledge Base article.

VictorOps.json

Edit Line 18 in the following config file so that it contains your Sensu API Endpoint you just copied instead of “https://alert.victorops.com/integrations/generic/SOMETHIHNG/alert/UUID” and place it in /etc/sensu/conf.d then, download the VictorOps handler and the integration is complete!
