System Log (4.2)
- Jenni Wallin
Events and errors encountered in the system are saved in the System Log. The System Log handles duplicate events within a time frame, and therefore every event and error has a first and last occurred date, as well as information on how many times it was repeated. You can select to filter out which events you want to see as well as delete selected events from the log.
The System Log table will display a maximum of 500 000 entries. If you want to modify the maximum number of entries, add the Platform property mz.systemlog.maxresults in the values.yaml file and modify the value.
To open the System Log, go to Manage → Tools & Monitoring and then select System Log.
If you have had the System Log open for a while, you can refresh the view by clicking on the Refresh button in the table action bar.
