Resolution

This issue is permanently addressed in SRM 4.9.  For all previous releases where this issue is encountered, the following workaround will fix the issue:-
  1. Login(SSH) to the impacted powerflex collector host
  2. Navigate to the directory /opt/APG/Collecting/Stream-Collector/emc-scaleio/conf 
  3. Make a copy of the file getvolumeinfo_querystats.xml to getvolumeinfo_querystats.xml.old
  4. Edit the file getvolumeinfo_querystats.xml

Modify Line# 75.  Change it from

extractions xpath-expression=" substring-after(//vtreeid, '_') " result-type="string">VTREEID</extractions>

to

<extractions xpath-expression="if(contains(//vtreeid,'')) then (substring-after(//vtreeid,'')) else (//vtreeid)" result-type="string">VTREEID</extractions>

  1. Save the file, restart the powerflex collector manager and allow a few polling cycles for data collection.
