This process monitor watches for the udev process to be running. Udev is a generic kernel device manager. It runs as a daemon on a Linux system and listens to events the kernel sends out if a new device is initialized or installed
A failure indicates that the udev service is down.
Check the service by running ps -ef | grep udev or by viewing the diagnostic in the Operations Manager Console. Start it by running "/sbin/start_udev" or by clicking the recovery link in the Operations Manager Console.
For root cause analysis, first check the system logfile (/var/log/messages), and view any related entries at the time of failure.
