when i look at the alert details it does not say which ports are affected...
ive checked the logs as well on a host and couldnt see anything in there either
im a bit stumped as to why this is happening... the security profile on the hosts has not been changed recently, its been static
has anybody seen this before?
is there a way I can see whats being blocked on the DVS ?
let me know if you need any more info...
thanks!
I've dealt with this before. You can't find the specific port in vR Ops. The summary metric is collected by vR Ops, but the instantiations are not collected. Best bet is to check the vCenter directly for blocked ports.
ok thanks for the info... do yo know which logs I should check on vcenter ?
I just found that one of our ports is showing up as blocked in vsphere... its quite possible that this is the cause of our issue
now to figure out why this is happening...
I could see a KB which says This can falsely trigger an alert.: VMware Knowledge Base
Check the override port policies on blocked port option.
To apply different policies for distributed ports, you configure the per-port overriding of the policies that are set at the port group level.
Edit the Blocking Policy for a Distributed Port or Uplink Port
