Problem Definition

From time to time users notice that issues have been deleted, and would like to be able to see who deleted the issue, and when it was deleted.

Suggested Solution

Provide an audit log for Issue Deletion.

Further possible outcome: Allow for deleted issues to be restored.

Workaround

There are a few workarounds here:

1. First is to use Webhooks, Then you can audit all the changes you need to even select some of them.
2. Second is to go to the instance home page at https://INSTANCE_NAME.atlassian.net/secure/Dashboard.jspa then scroll down, you will see the activity stream which has a RSS.
3. We can build this rule below to send a notification with information about the deleted issue in the future, using the Automation for Jira, a native feature in Jira. Follow these steps to access the Automation for Jira: Jira >> settings >> System >> Automation rules

Email information to add in the rule:

SUBJECT
Issue deleted {{issue.key}} - {{issue.summary}}

CONTENT
This issue was deleted.

Issue Key: {{issue.key}} 
Summary: {{issue.summary}}
Description: {{issue.description}}
Who delete the issue: {{initiator.displayname}}

You can have this email sent to a mailbox that you could go back to when you want to identify who deleted an issue. 

Enterprise Plan feature: Track user-created activity

Tracking user-created activity in the audit log is available when you upgrade your products to an Enterprise plan. Read more about Enterprise plans 

Workaround Via third-party apps

• We can even use issue-history-for-jira and restore-deleted-issues marketplace add-ons that could help Track, restore and also know the user who the deleted issues.
