Measurement threshold policy with two metric's evaluation

Question

Hello.
I'm trying to create policy, which accepts two metrics via opcmon. It works as expected, when I have single source and single evaluation in Measurement threshold policy, but if I add second source, policy converts to Perl Script evaluation, and I can't figure out, how to proceed with Perl threshold evaluation.
for example:
in source I have:
Source type: Program source
Short name: calculated_metric_short_name
Program: /tmp/calculate_metric.sh
Data source: CALC_METRIC_SCRIPT
Object: CALC_METRIC
Metric: CALC_METRIC_NAME

and Threshold limit (Perl Script):
***
if ( \$Policy->Source(calculated_metric_short_name) > 1000 )
{
\$Rule->Status(TRUE);
}else{
\$Rule->Status(FALSE);
}
***
Will it work?
How should Perl Eval Script look like?
How to access this metric in Performance dashboard?
Is there any guide/documentation for perl script evaluation?

Hello, 
 I'm not 100% sure you can do this using external scripts. I could not find an example where external script are used like this. Normally, you would store your values in coda which the monitor policy then uses - this is how most Management Packs (MP) work. 
 Most MPs run a scheduled action once every 5 minutes which adds your custom metric to coda (see https://docs.microfocus.com/doc/Operations_Agent/12.21/SubmittingCustomData ). Then u se these metrics within your monitor the policy. You also able to view the metrics in the Performance Perspective as an additional bonus. 
 Not directly related to your monitor question, but a fantastic example of getting and storing data in coda would be: Easily collect custom metrics using Perl and visualize in OBM . 
 Please contact me directly if you need more information about this - no worries. 
 I hope this answers your question, 
 Duncan
