Working with the event logs

If you are experiencing complex issues that require advanced troubleshooting, you may need to collect information from the ISDN gateway logs. Typically, you will be working with TANDBERG customer support who can help you obtain these logs.

Event log

The last 2000 status messages generated by the ISDN gateway are displayed in the Event log page. 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 ISDN gateway, TANDBERG 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 TANDBERG 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

Event capture filter

The Event capture filter allows you to change the level of detail to collect in the Event log traces.

You should not modify these settings unless instructed to do so by TANDBERG customer support. Modifying these settings can impair the performance of your ISDN gateway.

Normally, the capture filter should be set to the default of Errors, Warnings and Information for all logging sources. There is no advantage in changing the setting of any source without advice from TANDBERG customer support. The diagnostic information generated by the ISDN gateway can be very verbose and enabling excessive debugging without advice can cause the Event log to become full very quickly and is not advised.

Event display filter

The Event display filter allows you to view or highlight stored Event log entries. Normally, you should not need to view or modify any of the settings on this page.

Syslog

You can configure the ISDN gateway to send event messages to up to four syslog servers. To add or remove a syslog server, go to Logs > Syslog and make the changes you require. See Logging using syslog.

H.323

The H.323 log page records every H.323 message received or transmitted from the ISDN gateway. The log can be exported in an .xml file. By default the H.323 log is disabled because it affects performance, but Technical support may ask you to enable it if there is a problem with a unit in your network.

Audit log

The audit log records any user action on the ISDN gateway which might compromise the security of the unit, of its functions, or of the network. For more information, refer to Working with the audit logs.

Call Detail Records

In addition to the logs described above, the ISDN gateway can also store Call Detail Records (CDR) which may be used for auditing and billing purposes. Events in the log are displayed in the CDR log page. See Working with Call Detail Records for more details.
