You would need to have the analysis on the endpoint configured to pull the information. At that point, I believe you can query the result of an analysis by name but how to do that escapes me.
Create an analysis with a property that retrieves the data you want - the property uses client relevance so something like
lines of file "/tmp/perf_monitor_status"
Then from session relevance you can get value of that property.
Say the property is named performance_monitor_status
The session relevance will be something like
values of results of bes property "performance_monitor_status"
