Activity Log

You can search based on Date, Description, Username as well as the IP Address that initiated the action. Then you can Filter Log to filter what is being seen to match those requirements.

Admin Log
The Admin Log will show the times that an Administrative user logged in, as well as when they logged out. This can be useful to know when certain Administrators are logged in at a time, as well as when they had last logged in. This will also show the IP address, which can assist with identifying suspicious logins.

Module Log
The Module Debug Log can help to debug or identify possible issues that exist within a Module or remote API calls. By default, this will be turned off, however if there is an issue happening and you need to investigate the calls being made, you can Enable Debug Logging. Just make sure that once you are finished checking into this that you Disable it as well. Otherwise the Log may fill up pretty quickly.

Email Message Log
When WHMCS Sends an email to one of your clients, it will be listed in the Email Message Log. While this is useful for seeing emails that have been sent, especially more recent emails, you may want to view the Individual Email logs on the Client’s Profile page.
