This document explains the concepts of 'Audit Log', a section where you can audit and analyze what setup changes have been done on Opsview Monitor, from the addition and removal of hosts, to users logging in/out, applying changes and more.
After reading this section, a user should be able to filter the Audit Log, export the results, understand the different categories and more.
Go to Configuration > System > Audit Log:

Audit Log is essentially the 'history' view within Opsview Monitor; it will show what users have been doing, what changes have been made, by whom and when, and allow for the restoration of a previous 'known working setup' in the event of a configuration error.
The columns within the Audit Log table are:
**Ref: ** A system-generated unique ID for the given event / Audit Log entry
**Date & Time: ** The date/time of when the Audit Log entry was generated
**Username: ** The user who generated the Audit Log entry, i.e. the user who added the new host, or the user who performed an 'Apply Changes' from the Configuration menu.
**Category: ** The type of Audit Log entry (covered later).
**Activity Description: ** Detailed output for the Audit Log entry, i.e. the IP of the user who logged in, the details of the newly added host, etc.
**Changelog: ** The Change Log comment for that specific configuration change (only shown when this feature is enabled).
**Action column: ** Optional additional actions to perform a specific activity related to the entry, such as a 'Restore' button for configuration
**Note:** For users to be able to view the audit log, they will need ADMINACCESS and CONFIGUREVIEW permissions. See the section [Adding a New Role](🔗) for more information.
