Hi,
Can anyone help? I'm trying to setup a custom alert that will tell me if a node has been up for greater than 90 days but I'm getting the error shown below.

The custom poller is a transform of sysuptime time ticks to days, but when ever I hit OK I get this error. I've tried different 'values' e.g. rate, status numeric value etc.... but I get the same error. The only way I can get this configured is to choose 'Custom Node Table Poller' from the dropdown, but the alert doesn't fire when it should. I don't think this is a table value anyway.
Can anyone offer any advive,
Thanks
Matt
