Complex condition - Matching a field from a device poller and a field from a custom property

Hi there,

I am trying to setup a advanced alert which alerts me when a device is overheating. I have a custom device poller which queries a temperature sensor over SNMP to get a reading of the current temperature.

I want to add advance alert which compares this value with a "TemperatureAlertValue" I have setup as a Custom Property which will contain the value at which I want my alert to trigger (because certain equipment I want a alarm when it reaches 30C and others at 40C for example).

However, if I setup a Complex Condition then as soon as I select to compare two fields from seperate groups (One from my Custom Node Poller and the other from my Node) then it will clear the previous selection. How can I get around this?

Thanks in advance for your help!

You should be able to do this.

- Set the Type of property to monitor to "Custom Node Poller". Leave it set to this - you don't need to change it. Your Node custom properties should still show up in the menu options when you have "Custom Node Poller" selected.

- Use the Complex condition:

Field Numeric Status is greater than or equal to Field MyThreshold

(Assuming your custom Node property is called "MyThreshold")

Hi Cdoyle,

Thank you for your help. Thats how I used to have it setup, however I now want to use a custom properties to compare against the Nodes status. I tried typing in my variables name into the last field but that did not work. If I setup a complex condition and select "Network Nodes | Custom Property | TempAlertLevel" then it will clear my first field and set it back to "*".

It seems like one of the two conditions being compared has to be a value, as soon as I select to compare two fields it will clear the other one.

If my memory serves me correctly this will happen if the two fields you are choosing do not have the same data type.

sHey guys,

Thanks! You are both correct! I missed that there is a "Status" and a "Numeric Status" (as cdoyle did suggest). After changing my field from Status to Numeric Status the comparison works perfectly!

Thank you very much for your help!
