OpsGenie is a 3:rd party alert and incident response tool. Composer supports pushing application errors to OpsGenie.
OpsGenie can also forward alerts to other tools such as Slack and Atlassian Jira. It also supports SMS- and voice messages.
The following chapter describes how to integrate Composer with OpsGenie. Configuring OpsGenie itself is out-of-scope for this guide.
