    NPM 12.1 - How to access custom node/interface properties when evaluating poller formulas

    mattwisner

      Hello,

      I am trying to setup some custom gauges in my SolarWinds dashboards and need to access custom node/interface properties in my poller's formula.  I have checked the NPM Admin Guide, to no avail.  THWACK does have an article from April, 2009 (see below), but when I try this and TEST in "Transform Results Wizard" I get an error "Object reference not set to instance of an object".

       

      Is it possible to access custom node/interface properties when evaulating poller formula?

       

      Thanks in advance,

      -Matt

      Ok so this one is a bit tricky but it can be done...  The first thing you need to do is create a new Universal Device Poller that will return a numeric value.  I chose ifNumber (1.3.6.1.2.1.2.1).  Assign that to your node but dont store history or add any web display.  Next create a new transform and for your formula enter

      {ifNuber}+${Nodes.YourPropertyNameHere}-{ifNumber}

      Assign that to your node and add it to the node/interface details view as a guage and it should show you your custom property value in a guage.
