Help simulating ASM syslog events at error level and above for testing?

Does anyone have a suggestion on how to generate system events on an ASM at error, critical, or emergency levels for testing remote syslog logging?

  • Hi,

    you can use the logger command to generate a log message manually

    logger -p <facility>.<level> "<descriptive message>"

    [admin@F5BIPIP:Active:In Sync] ~ # logger -p local0.notice "testing LTM facility level notice"
    [admin@F5BIPIP:Active:In Sync] ~ # tail -f /var/log/ltm
    Apr 24 08:16:14 F5BIPIP notice admin[29591]: testing LTM facility notice

      ​That worked perfectly, thanks!  The events even show up in the GUI.
