# Using oammon

Use the oammon board monitoring utility to monitor board and driver error messages on AG and CG boards. oammon can perform the following tasks:

- Monitor boards for errors and other messages from the OAM system

- Capture messages in a log file (oammon.log)

- Send an alert notification message to all NMS OAM client applications

Most NMS Communications boards support BootDiagnosticLevel board keywords that enable you to specify the type of board diagnostic tests that take place when you boot the board. When a diagnostic test fails, board level error messages indicate the test number of the failed test. You must be running oammon to view diagnostic results returned through board level errors. For more information about board keywords that control boot time diagnostic tests, refer to the board-specific installation and developer's manual.

If monitoring boards on multiple hosts, start a separate instance of oammon for each host. Each instance monitors one host only. For more information about oammon, refer to the NMS OAM System User's Manual.

Note: ctdaemon must be running to use oammon. Refer to the Natural Access Developer's Reference Manual for more information on starting ctdaemon.
