Version 1.8.8                                     January 2012                                    o2hbmonitor(8)

o2hbmonitor  is  a  utility  to  monitor the disk heartbeat in the o2cb cluster stack. It tracks the time
       elapsed since the last heartbeat and logs messages once it exceeds the warn threshold.

       By default, it runs as a daemon and logs messages to the system logger. It can be started at any time and
       stopped using kill(1). It does not affect the functioning  of  the  heartbeat  thread.  It  is  typically
       automatically started during cluster online and stopped during cluster offline by the o2cb init script.

       This utility expects the debugfs file system to be mounted at /sys/kernel/debug.
