zenoss 6 Page command

  • 1.  zenoss 6 Page command

    Posted 02-25-2021 02:05 AM

    Hello,

    I moved from zenoss4 to zenoss6 and noticed the trigger notification "page" is missing.  I have a device that sends the sms messages directly connected to my zenoss server.
    I have already configured the page command (refering to my own script) in the advanced settings, and I am able to sent a test page to a user without problems.

    Since I can't use the page trigger anymore, I decided to try and use a command trigger instead.  The problem I ran into is that I can't pass on the pager/telephone in the command.  I've tried to use $RECIPIENT as used in the advanced settings but I get a BadTalesExpression when the notification is triggered.

    Traceback (most recent call last): File "/opt/zenoss/Products/ZenModel/actions.py",
    line 332, in execute self.executeOnTarget(notification, signal, target) File "/opt/zenoss/Products/ZenModel/actions.py",
    line 729, in executeOnTarget self._execute(notification, signal, environ) File "/opt/zenoss/Products/ZenModel/actions.py",
    line 766, in _execute command = processTalSource(command, **environ) File "/opt/zenoss/Products/ZenModel/actions.py",
    line 114, in processTalSource raise BadTalesExpresssion(message) BadTalesExpresssion: Unable to perform TALES evaluation
    on "/usr/bin/ssh -q -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null zenoss.ugent.be "/home/zenoss/zscript/sendsms $RECIPIENT testmessage"

    How can I use the pager number from the zenoss user database in my notification ?

    Thanks !

    Hello Jeroen,
    Dag Jeroen,

    Here is how I did it. Under Advanced -> Settings -> Settings, I filled in "Page Command" with this : "/opt/zenoss/var/ext/bin/zenoss_smseagle.py $RECIPIENT".
    You can also see that I moved the script to DFS location, which makes it safe to survive through upgrades.
    The message itself is read from the stdin: msg = sys.stdin.read()

    Nice to read that Zenoss seems to be used in UGent.

    Groeten,

    Laurent

    Hi Laurent,

    Thank you for the reply !  We have been running zenoss over 10 years now to monitor our network devices.

    The page command under the Advanced Settings does work. I can send a test sms/page from the Advanced Settings User page and it arrives without problem.
    Only when an event triggers a COMMAND based Notification using the $RECIPIENT in the command itself, I get a BadTalesExpresssion.

    I've checked the zenactiond log and normally the "Target:" contains the page number or the email adres in case of an e-mail action and the "Event:" the message itself.  I would assume that $RECIPIENT would pass on the page number but that doesn't seem to work. 

    Do you mean I have to start the script from a different location or in a different way ?


    Many thanks,

    Jeroen

    Hello Jeroen,

    I can only remember that I had some issues with the COMMAND notification, but I can't remember what exactly. There must be a reason why I used the Page command. I'm not sure, but I think that's the only way to pull out the user's phone number. That's something I should check.

    The location of your script will not impact the variable you can import into it. However, placing it in a safe place will assure you that it remains in place even after container restarts and upgrades.

    Cheers,

    Laurent

    Hi Laurent,

    Thanks for the reply.  It's unfortunate that they removed the Page Action trigger going from zenoss 5 to zenoss 6.  So now there seems no way to pass on the configured page number in an event trigger.

    Regards,

    Jeroen
