Trace Logger group

Field

Description

Log File Maximum Size

The maximum size, in megabytes, that the log file can be. Once the log file reaches this size, the system starts a new log file. If starting a new log file causes the number of logs to exceed the Number of Logs to Retain setting, the system deletes the oldest file before it starts the new file.

Enter a whole number from 1 to 100. The default is 10.

Note:

Due to the volume of trace messages from the following components, the number of log files retained by the system are set higher than the number you specify in this field. The actual size is as follows:

  • Endpoint Manager ($AVAYA_MPP_HOME/logs/process/MediaMgr/EndPointMgr): 5x

  • Media Manager ($AVAYA_MPP_HOME/logs/process/MediaMgr/MediaManager): 2x

  • Session Manager ($AVAYA_MPP_HOME/logs/process/SessMgr/*): 2x

Number of Logs to Retain

The maximum number of log files the system can retain, including the current one. Once this number of log files exists, the system deletes the oldest log file before starting a new one.

Enter a whole number from 1 to 5. The default is 2.

Note:

Due to the volume of trace messages from the following components, the number of log files retained by the system are set higher than the number you specify in this field. The actual size is as follows:

  • Endpoint Manager ($AVAYA_MPP_HOME/logs/process/MediaMgr/EndPointMgr): 5x

  • Media Manager ($AVAYA_MPP_HOME/logs/process/MediaMgr/MediaManager): 2x

  • Session Manager ($AVAYA_MPP_HOME/logs/process/SessMgr/*): 2x

Field

Description

Transcriptions Retention Period

How long an MPP keeps detailed session transcriptions for the sessions that it handles.

Enter a whole number from 0 to 999. The default is 14.

Record Handling on MPP group

Field

Description

Session Data

Whether an MPP keeps detailed records about the sessions that it handles. Experience Portal uses this data to create the Session Detail report and Session Summary report.

  • Enable: Select this check box to record session data on all MPPs.

  • Retention Period: The number of days to retain the session data. Enter a whole number from 1 to 999. The default is 14.

VoiceXML/CCXML Log Tags

Whether an MPP keeps the CCXML and VoiceXML Log tag data from the application sessions transacted on that server. If desired, Experience Portal can download the Log tag data and display it in the Application Detail report and Application Summary report.

  • Enable: Select this check box to record application on all MPPs.

  • Retention Period: The number of days to retain the session data. Enter a whole number from 1 to 999. The default is 14.

Categories and Trace Levels section

Performance tracing is a valuable troubleshooting tool, but it can adversely impact Experience Portal system performance if you set all categories to Finest on a busy production system. If you need to troubleshoot a particular area, you must set specific categories to Fine and examine the resulting output to see if you can locate the issue. If not, set the level to Finer and repeat the process. If you still need more data, then set the level to Finest and keep a close watch on system resource usage.
