Auto comment when an issue priority is Critical

[andrea price]

We would like an automatic comment added to issues whenever the Priority is set to Critical.  This is so we can bring it to the assignees attention asap.

Hi @andrea price 

What does "Critical" mean for a work item for your team and how do they normally respond to such items?

As individual Jira users could suppress notifications like comments, will the assignee still get the visibility you are looking for increasing if they do not see the comment?

Kind regards,
Bill

You could use Automation for Jira - Server Lite. It's a free Add-On that would allow you to create a rule for this.

Event Listener would satisfy this.
A lot easier if you have the Scriptrunner plugin.
