Working with the Event Logs
If you are experiencing complex issues that require advanced troubleshooting, you may need to collect information
from the MCU logs. Typically, you will be working with Customer support who can help you obtain these logs.
Event Log
The last 2000 status messages generated by the MCU are displayed in the Event log page (Logs > Event log). In
general these messages are provided for information, and occasionally Warnings or Errors may be shown in the Event
log. The presence of such messages is not cause for concern necessarily; if you are experiencing a specific problem
with the operation or performance of the MCU, Customer support can interpret logged messages and their
significance for you.
You can:
■ Change the level of detail collected in the traces by editing the Capture filter page. You should not modify
these settings unless instructed to do so by Customer support.
■ Display the log as text: go to Logs > Event log and click Download as text.
■ Change which of the stored Event log entries are displayed by editing the Display filter page
■ Send the event log to one or more syslog servers on the network for storage or analysis. The servers are
defined in the Syslog page. For more information, refer to Logging using syslog
■ Empty the log by clicking Clear log.
