Can token values be evaluated in a complex datapoint?

Hi Jared, Apologies for the delayed response.

It’s not something I have lots of experience with (To be honest I’d usually perform this logic in the collection script itself and not complex datapoint) but I may have a working solution:
 

Essentially, I explicitly defined the output as a float before dividing as I know Groovy has a tendency to label everything as strings by default.

wv = "##WILDVALUE##"

if(wv=~"AWS"){

bps = output["BYTESRECEIVEDPERSEC"] 

bps_scale = (output["BYTESRECEIVEDPERSEC"].toFloat())/1024

return bps_scale

}

else{

return 0

}   

(Note the default datapoint is a derive so I needed to make it a gauge as thats whats being pulled using the OUTPUT[] method.

yep, to get that in you use:

// get a host level property
property = hostProps.get("<propname>")
// get an instance level property
property = instanceProps.get("<propname>")
// get a task level property (in case you don't know where the prop might be)
property = taskProps.get("<propname>")

the value of the property would be stored in the property variable. More here.

Hi Jared, I created this Groovy scripted Complex datapoint which returns 1 if the wildvalue is “drive1” and 0 otherwise

wv = "##WILDVALUE##"

if(wv=="drive1"){

return 1   

}

else{

return 0

}   
 

It uses the same approach that can be used to access the WILDVALUE in a standard data collection script.

Some things to note, the DS I tested on was a SCRIPT (I don’t know with certainty if this datapoint would work in the same way for other collection/discovery methods).

Hope this helps!

thanks Chris, this helped me fill in the gap. I’m using this in the WMI DS for WinVolumeUsage, and this datapoint is now polling as I need it to evaluate only the remaining free space on C: drives. 

osDrive = property = instanceProps.get("auto.driveletter")

freeSpace_scale = (output["FREESPACE"].toFloat()/1024/1024/1024)

if(osDrive=="C:"){

return freeSpace_scale

}

Thanks again for the assistance!

Sorry I didn’t state what type of DS this was--it is WMI.

Your replies were both a lot of help. I added DRIVELETTER as a WMI class property name, and then constructed this groovy script with the complex datapoint name “GB_Free_C_CHECK”:

osDrive = property = instanceProps.get("auto.driveletter")

if(osDrive=="C:"){

return 1

} else{

return 0

}

then, I’m working off that datapoint to evaluate another expression datapoint:
if(GB_Free_C_CHECK,FreeSpace/1024/1024/1024,0)
 

Ideally I would like to combine both these into one for simplicity. But I can’t find how to evaluate instance properties within an expression (##INSTANCE## doesn’t validate), or perform math operations within a groovy statement (anything like freeSpace = (output["FREESPACE"] / 1024) returns NaN).
