The product page of Watcher mentions the option to alert Jira.
Get Notified the Way You Want
Easily set up email alerts when incidents occur, or integrate Watcher into your existing monitoring infrastructure via webhook to send alerts to JIRA, HipChat, PagerDuty, Slack, and more.
I can't seem to find how to do this and how it works. I found ElastAlert on the internet and this is able to create tickets in Jira or even update a ticket. Can Watcher do this also? How does it work ?
