Unmanaged devices showing up in M&R

Products

• VMware Smart Assurance

Issue/Introduction

This article explains about the below issues:

 

• Devices unmanaged in Smarts are not polled for availability therefore reporting 100% availability in M&R reports may not be accurate.
• M&R Solution Pack for Smarts collects data from all devices within the Smarts IP domain topology regardless of managed state.
• Smarts unmanaged devices reporting 100% availability in M&R reports | unmanaged devices showing up in M&R

Environment

M&R - 7.x

Cause

• A device which is unmanaged in Smarts is not polled for availability and therefore the attribute IsUnresponsive remains in the default state of true.
• M&R Smarts Solution Pack collects this attribute to determine the reachability of the device which in this case may be inaccurate.

Resolution

• The following can be added to Collecting/Smarts-Collector/emc-smarts/conf/pm.xml which will drop collection from unmanaged devices:-

<post-filter-script script-id="UnmanagedDevice" in="IsManaged"/>

• This line is placed directly after the line below (the containment may vary depending on the W4n version)

<data id="Device" class="UnitaryComputerSystem"

                containment="ComposedOf HostsServices" start="true">

Then add the additional <script> lines towards the bottom of the same file:-

<script id="UnmanagedDevice" in="IsManaged"> 

                <![CDATA[ 

                ctx.str(IsManaged).equals("true") 

        ]]> 

        </script>

• For example these can be placed after <script id="bandwidth-capping-script" in="utilPct inRate outRate speed">  .. </script>
• A restart of the Smarts collector will be required to pick up this change.
