    Node Tabular Universal Device Poller

    mmarchand

      I'm trying to create an alert from a Node Tabular Udp for DMVPN tunnel Up or Down

       

      The poller gets the IP address of the remote peers

       

      Ex

      cikeTunRemoteAddr - Label          cikeTunRemoteAddr

      15589                                             10.0.2.23

      15590                                             10.0.1.24

      15591                                             10.0.3.25

       

      The two important value to look for are 10.0.2.23 and 10.0.1.24 all other tunnel address polled are not really important since they are Dynamic

       

      I want to know when 10.0.2.23 is down so I created the following alert triggered condition

       

      The actual trigger condition:
      All child conditions must be satisfied (AND)
        Custom Table Poller Current Status - Current Value - does not contain - 10.0.2.23
        Custom Table Poller Current Status - Current Value - contains - 10.0.1.24

       

      My poller table says that the two value are present so the condition should not triggered since it contains 10.0.2.23

      But the alert says it will triggered immediately and does trigger? Why

       

      What is wrong is there something I don't see.

       

      By the way, I just started using Solarwinds :-)

       

      Thanks

          The way the logic works on table pollers is that it evaluates each row of the poller table separately, so the rule you have there would alert any time 10.0.1.24 is in any table poller at all.  It doesn't check the whole table for those two values as a set.  You could probably get away with specifying the rowid that currently holds 10.0.2.23 and if that rowid is not 10.0.2.23 then trigger the alert.  I don't know on that particular poller if the rowid would change to something else the next time the tunnel came up though, probably would want to do some experimenting to be sure of how it behaved.

              Hi Marc

               

              Thanks for the enlightenment about table pollers logics, The multiple test I did with the alert conditions directed me to see this behavior but since I do not have much experiences with Solarwinds I though that I did not do the right thing.

                

              I know about the RowID and did the test, unfortunately it change every time the tunnel go down/up, so this is not a possible scenario for alert.

               

              I will have to look at some other OID's or will try to do it with the routing neighbors.

               

              Or if anybody out there have another solution please let me know

               

              Thanks
