I have had this issue at a customer, where vCops after running for some time, came with this administrative alert.: "number of resources exceeds supported limit"
After some searching on the internet i found 2 articles that had something about this:
They both pointed to a advanced setting that should be set, but nothing about the value, so i had to do some research, and found that the default value for this:
maxNumberOfResourcesSupported = 10000
After some talk with VMware we have set this to:
maxNumberOfResourcesSupported = 99999999
The paramter is set in /usr/lib/vmware-vcops/user/conf/analytics/advanced.properties, on both VM i the vApp, not sure of that's necessary, but the configuration file is on both.
I then restarted vCops and after some time the error disappeared.
