<![CDATA[Simple question - variable which holds result of icmp when doing status polls]]>I have my nodeUpDown custom variable auto binding and unbinding working - except for the last piece - updating this custom variable when status polling.

I do NOT want to just use the event and do it via event processing - Event Policy processing can get behind so this way avoids waiting - it updates what we look at immediately.

I want to add to the Status hook the setting of the nodeUpDown based on the ICMP ping response.
If I can ping the device - set it to up. If I cannot ping it, set it to down.

Something like this below added to the status polling hook script - once I know the variable that holds the ICMP response.

if (($node->icmpresponse == "no")) {
   newstate = "Down";
   oldstate = GetCustomAttribute($node, "nodeUpDown");

         if (newstate != null)
            {
             if ((newstate imatch "Down"))
                 {
                  BindObject(FindObject("AllDown"), $node);
                  SetCustomAttribute($node, "nodeUpDown", newstate);
                 }
   }
if (($node->icmpresponse = "yes")) {
   newstate = "Up";
   oldstate = GetCustomAttribute($node, "nodeUpDown");

         if (newstate != null)
            {
             if ((newstate imatch "Up"))
                 {
                   SetCustomAttribute($node, "nodeUpDown", newstate);
                   UnbindObject(FindObject("AllDown"), $node);
         }
   }

}

Coding style - mine is mostly a hack and slash approach to something else I have seen as an example or that I know works. Once it works, rather than go back and clean it up - more trial and error - I move onto the next highest priority task.

The more I do with NetXMS, the better I will get.

Between this and the runtime flag for unreachable - very, very happy person I am today 🙂

if (($node->icmpresponse & 4) != 0)
   // state is "down"

Also few comments on script itself - purely style/clarity, not functionality:

  1. You may use direct comparison instead of regexp match if you are loking for exact match, i.e.

(newstate == "Down")

instead of

(newstate imatch "Down")

  1. No need for checking status twice, just can just use else:
if ($node->icmpresponse == "no") {
}
else {
}

Best regards,
Victor
