How can we monitor configuration changes?
Since version 2.1.x, configuration changes are noted in the audit log of Jira/Confluence. Additionally, you can see the user who did the change, e.g.

Additionally, you can find the information by running the following database query:
- select "LAST_MODIFIED_BY", "LAST_UPDATED" from "AO_F58FCA_ALBA_CONFIG" order by "ID" desc limit 1;
Output:
- LAST_MODIFIED_BY | LAST_UPDATED
- ------------------+---------------
- admin2 | 1637851297239
LAST_MODIFIED_BY refers to the username and LAST_UPDATED is the unix timestamp of when the change was saved. You can use websites like https://www.unixtimestamp.com/index.php to convert the timestamp
