Configuring max thresholds on DCI

[wraythe]

Hi Guys,
 I've got an issue where the DCI gets a random value of a ridiculous size. (Monitoring a Sophos appliance interface throughput)
 I should be seeing up to 100mbps, but it 'spikes' to 4.5gbps which isn't realistic.
 

 I tried adding a filter into the DCI transformation script to return null if the value is excessive, but it isn't making a difference to my graphs.

 Not sure if it's my transform script at fault.

Really hope it is something simple

Hello!

I'v solved in this way:

if (real($1*8.0) > 10*1024*1024*1024.0)
	return 0;
return $1*8;

in my case the cap is to 10Gib/s, change it according to your limit.

Marco

Thanks Marco, what does the real function do?

Thanks Marco, what does the real function do?

Is used to manually convert the variable to a floating point. NXSL is loose typed programming language and the system should  automatically determine each variable type but I had problem to have it working correctly and that is the workaround I found.
