Process Udev Service Health

Microsoft.Linux.SLES.12.Process.Udev.Monitor (UnitMonitor)

SUSE Linux Enterprise Server 12 Process Udev Monitor

Knowledge Base article:

Summary

The udev daemon is not running. Check the Diagnostic and Recovery results to see if further action is required.

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.

Causes

A failure indicates that the system-udevd daemon is not running.

Resolutions

Check the service by running ps -ef | grep systemd-udevd or by viewing the diagnostic in the Operations Manager Console. Start it by running "systemctl start systemd-udevd" or by clicking the recovery link in the Operations Manager Console.

For root cause analysis, first check the system log file (/var/log/messages), and view any related entries at the time of failure.
