CDM Computer has been rebooted

    I am getting an alarm from the CDM probe saying that the computer has been rebooted. The message I get is "BootAlarm: Computer has been rebooted at <unable to determine>", if I clear it the message comes back again eventually. Can anyone tell me how to clear this please as I assume the probe is having issues because it cannot determine the date of the error?

    Thank you for any help

    Just some thoughts but is the Message ID BootAlarm configured to use the default varable $boot_time in the CDM probe? If so what happens if you create a test alarm that you know will trigger and use the variable $boot_time in the message text? What time is returned?

    I started having the same false alarm with CDM 5.02 and came on here to see if anyone has a solution for this. We've had several of these false alarms happen on servers that weren't rebooted and whose uptimes looked good.

    I'm going to try removing the cdm.data file which holds a timestamp used to compare against the system uptime. Then I'll restart CDM and see if it creates a new cdm.data, otherwise I'll redeploy CDM. I'll post back to let you know how that goes.



    Edit: I actually was able to: shift + right click > raw configure > edit data file. Delete the contents of the data file, save, and restart CDM. CDM will put a new uptime value into cdm.data.

    This is a known bug/defect with the CDM probe. There are several outstanding issues currently opened against this feature of the CDM probe. A potential fix was provided just last week and needs heavy testing.

    In case this helps anyone, what I did was make a pre-processing rule in the NAS to exclude these alarms with the following filters:


    - NMS Probe Name: cdm

    - Message String: /^BootAlarm(?=.*20)/

       *** Make sure to negate the message string filter (ie. make sure the little square above the filter is red) ***


    All this does is do a lookahead in regex looking for the '20' in the year (eg. 2014, 2015, etc..) and matches if it's not found.
