# Maintenance and Software Logs

Maintenance Logs record all maintenance-related information, including anything that affects the functioning or capacity of the system in any way. Examples of typical Maintenance Log entries are those reporting the busying of circuits, or those listing circuits which failed diagnostic tests.

NOTE: Pre-Save/Post-Save log entries for License and Options changes and Day/Night Service changes that were posted in the Maintenance logs prior to MCD Release 5.0 are now logged in the Audit Trail logs.

Software Logs record unusual activities within the system.

You can display maintenance and software logs as follows:

- All Maintenance and Software Logs

- Maintenance or Software logs:

- All Logs

- Error Logs only, showing all events that caused an error in the system

- Warning Logs only, showing all events indicating a potential error in the system
