Extreme Management Center Log Files

Extreme Management Center log files collect alarm, event, and trap information for Extreme Management Center Console and Extreme Management Center applications, and the devices on your network. The log files are displayed in the Extreme Management Center Event View (in the Console main window). By default, there is a Console log file and a log file for each application, as well as a Traps log and a Syslog log. In addition, the Server Information window provides a Server log.

The following sections provide information on each log file including a description of the log file, where the file is located, the log file archive behavior, and whether the log file is configurable.

Extreme Management Center Application Logs

The Extreme Management Center application logs record alarm and event information for the Extreme Management Center Console application and any other Extreme Management Center applications you've enabled. You can view the application logs in the Extreme Management Center Event View. The Event View provides a separate tab for each application and displays the most recent 10,000 entries (table rows) for each log. Log files are automatically archived when their size reaches five megabytes and a new log file is opened. Archived log files are time-stamped and saved to the <install directory>\appdata\logs directory.

You can use the Event Logs Options view (Tools > Options > Suite Options > Event Logs) to configure two application log file parameters. The "Number of Event Logs to Limit" option lets you set a limit to the number of application log files saved in the logs directory. The "Number of Rows to keep in table" option lets you set the number of entries (table rows) that will be displayed in the application logs (as well as the Traps log and the Syslog log) in the Event View.

Syslog Log

The Syslog log shows events from devices that are configured to use the Extreme Management Center Syslog Server. The log records all the TFTP and BOOTP messages received for devices modeled in the Extreme Management Center database. You can view the Syslog log in the Extreme Management Center Event View. The Syslog log file is automatically archived at midnight each night or when the file reaches the maximum file size of one megabyte, and a new log file is opened. Archived log files are saved to the <install directory>\appdata\logs\syslogs directory and a maximum of 10 files are saved.

On Windows systems, the Syslog file is configurable using the .nssyslogd.cfg file located in the <install directory>\services directory. In the .nssyslogd.cfg file you can set the maximum file size and the maximum number of syslog files saved. On Linux systems, syslog is part of the operating system and is not configurable using an Extreme Management Center file.

In the Event Logs Options view (Tools > Options > Suite Options > Event Logs), the "Number of Rows to keep in table" option sets the number of entries (table rows) displayed in the Syslog log (as well as the application logs and the Traps log) in the Event View.

Traps Log

The Extreme Management Center SNMPTrap Service (snmptrapd) receives SNMP trap and inform messages from your network devices and logs them into the Traps log. You can view the Traps log in the Extreme Management Center Event View.

You can use the trapd.conf file located in the <install directory>\services directory to add new traps and configure event definitions.

In the Event Logs Options view (Tools > Options > Suite Options > Event Logs), the "Number of Rows to keep in table" option sets the number of entries (table rows) displayed in the Traps log (as well as the application logs and the Syslog log) in the Event View.

Traps log files have the following default archive parameters:

  • A Traps log file is automatically archived when its size reaches one megabyte and a new log file is opened.
  • A maximum of 10 Traps log files are saved to the <install directory>\appdata\logs\traps directory.

These archive parameters can be changed by adding options to the beginning of the first line of the nssnmptrapd.cfg file located in the <install directory>\services directory. Add the -maxfiles option to set the maximum number of files and/or add the -maxsize option to set the maximum size of the file (maximum size allowed is 2 gigabytes). The following example shows the first line of the file with the -maxfiles option set to a maximum number of 15 files and the -maxsize option set for a maximum file size of 100 megabytes.

-maxfiles 15 -maxsize 100000000 -O bs -n -p 162 -z "C:\Program Files\Extreme Networks\NetSight\services" -o "C:\Program Files\Extreme Networks\NetSight\appdata\logs\traps" -c "C:\Program Files\Extreme Networks\NetSight\appdata\snmptrapd.conf" -M "C:\Program Files\Extreme Networks\NetSight\appdata\System\mibs;C:\Program Files\Extreme Networks\NetSight\appdata\System\mibs\MyMibs" -m SNMPv2-SMI;IF-MIB;all

Server Log

The Server log displays all the events for the Extreme Management Center server. It can be viewed on the Server Log tab of the Server Information window (Tools > Server Information). A new Server log is created every day. Previous logs are dated and saved to the <install directory>\appdata\logs directory. If the Extreme Management Center Server is local, you can view previous logs using the File sub-tab on the Server Information tab in the Server Information window.

You can use the Event Logs Options view (Tools > Options > Suite Options > Event Logs) to limit the number of server log files saved in the logs directory. This can help you control total disk space usage.

You can configure Server log properties in the log4j.xml file located in the <install directory>\jboss\server\default\conf directory.
