vROps – One or more ports are experiencing network contention – Temporary Fix

So VMware have admitted that the alert seen in vROps 6 for the below error and have a KB article written for it.

vROPS error

Unfortunately the resolution says to disable the DVPortGroup Dropped Packets alert, this turns out to be easier said than done.

As an alternative fix I have looked at the configuration for the Alert Definition to allow people to delete the current alert and re-create it if\when vROps 6.0.x comes out and the fix is present there.

01

Prior to deleting the Alert definition go to the alert and take a note of the text for the alert “One of more ports are experiencing network contention” because we are going to use that to recreate the alert definition at a later time.

02

Click on the Content tab (2nd from right) and click on the Alert Definitions

04

Now you have two options here.

1. Delete the Alert Definition (simply hit the red X to delete)

2. Create the Alert Definition if you previously deleted it.

The following instructions assume you have deleted the alert and want to recreate it.

Click on the Green + to create a new Alert Definition.

06

Paste the name that was previously saved “One of more ports are experiencing network contention" in to the Name box.
