Why cannot show the 3rd plugin in vSphere Flex Client?

Hi laurentsd,

We recently encountered a tricky customer case, there are three linked multiple vCenters in customer's environment. The problem is our plugin cannot show in one vCenter, but it is normal in other two vCenters. So we collected the logs in that problematic vCenter, then analyzed them and found many same clues like below:

[2017-11-21T07:36:58.681-07:00] [INFO ] http-bio-9090-exec-10        70000110 100006 200002 com.vmware.vise.extensionfw.ExtensionManager                      Package is filtered out - com.emc.vsi.plugin:6.9.2.31

We are curious that why our plugin is filtered out in that vCenter and no other more valuable messages in logs, but we found some SRM issues and we are not sure whether SRM issue is the root cause or the Center itself has some problems.

Could you help to check the log for giving your any ideas or suggestions? Thanks in advance.
