This article provides information on checking changes made within your Kayako Classic instance.
You can always check the changes made within your instance from the Activity Log in the admin control panel. It logs every activity performed in the admin control panel and the staff control panel such as inserting new staff users, editing new email queues, deleting tickets, etc. These logs give an insight into the activities in the helpdesk and can be found at Admin CP > Logs > Activity log.
From there, you can see what activity was done at which instance, the user who made the change, their IP address, and the date and time the change was performed.
The log storage duration can be configured by updating Admin Control Panel > Settings > Server settings and performance > Log retention time.
The Log retention time is the number of days after which logs will be deleted from the helpdesk.
NOTE: You need admin access with "manage helpdesk settings" permission to configure the log retention time.
