Quick Fix: VCSA Web Client 6.0 Throws Monitoring Errors
This quick fix post is for those out there who are still using vCenter Operations Manager 5.8.x and are or thinking about deploying or upgrading to vCenter 6.0…I came across this annoying situation all of a sudden while working on a new vCenter instance when the Web Client started to report the error shown below.
This can be ignored by clicking no and you will still be able to operate most areas of the Web Client but you will find that Monitoring and Health pages fail to load and give you a generic Error #2036 as shown below.
It took me a while to realize that the error was related specifically to the monitoring modules and it finally clicked in my head that the error started happening when I Registered the vCenter against my lab vCOPs instance. I was still running vCOPs (not vRA) and the instance hadn’t been upgraded to the latest build. Having a look through the VMwareKBs I came across KB 2111224 which explained the cause.
This issue occurs because vRealize Operations Manager versions prior to 5.8.5 are not supported in the vSphere 6.0 environment.
Upgrading the vCOPs Appliances to build 5.8.5-2532416 sorted the issue and I was able to browse through the Web Client without the error and have the integrated Health Monitoring work without issue.
