Server Reports for Physical and Swap memory are showing different Values between Smarts and MnR

Products

• VMware Smart Assurance

Issue/Introduction

Smarts is collecting data on physical memory and swap memory and the MnR reports show a different Value.

Environment

Watch4Net/M&R - 7.x

Cause

Physical memory and Swap Memory have identical formula/values in Watch4net

Resolution

The report definition, both Memory Used - Physical and Swap uses 'System RAM' only and hence, have same values. Please check if these metrics are received from SMARTS.

<node name="Memory Used (%) - Physical" order="4" singleNodeId="e28f5a86" type="entity">
    <property xsi:type="NodeFilter" filterExpression="parttype=='Memory' & (part='Real%' | part='Physical%' | part='%System RAM%') & !(name=='LargestFreeBuffer')"/>
 
<node name="Memory Used (%) - Swap" order="6" singleNodeId="e06be6d7" type="entity">
    <property xsi:type="NodeFilter" filterExpression="parttype=='Memory' & (part='Swap%' | part='Virtual%' | part='%System RAM%') & !(name=='LargestFreeBuffer')"/> 

 

• To resolve the issue, make the needed modification to the report definition to use the "displayname" value from Smarts for paging space.
  For example if the displayName value from smarts references /dev/swap/ replace the value for System RAM as follows:

<node name="Memory Used (%) - Swap" order="6" singleNodeId="e06be6d7" type="entity">
    <property xsi:type="NodeFilter" filterExpression="parttype=='Memory' & (part='Swap%' | part='Virtual%' | part='%/dev/swap%') & !(name=='LargestFreeBuffer')"/> 

• Restart tomcat aftter making the change with the following command from /APG/bin

    ./manage-modules.sh service restart tomcat Default
