WQL Query Datapoint cant do Expressions or Scripts?

Would suggest switch it over to a full groovy/powershell script to collect the information. Then you can have real enums and convert the strings to numbers directly in the script. A lot of LM existing scripts this way. For example you can look at Microsoft_Windows_Services. You might be able to actually clone that one and re use it for your purposes.

Now that I HIGHLY suggest you order your status codes from good to bad. Because thresholds can't use and/or (like "=1 or =2"). So I would order your status to be something like:

0 StartPending
1 Running
2 ContinuePending
3 PausePending
4 Paused
5 StopPending
6 Stopped

(I'm guessing the order). That way you can have a threshold of like "> 3 6". It also easier to read in a graph or color code in a table.
