Good morning to all of you,
We're finishing up configuring our new production VMware 6.7 based cluster, however, we're experiencing kind of strange issue associated with Alarms and particular reset rules. The case is that we don't get email notifications when 'Network connectivity lost' error is normalized and turns Green after we get any ESXi host back online. The same applies to the situation when we shutdown one port from a particular port-channel group (then network uplik redundancy is lost). We get email notifications informing us that network connectivity or uplik redundancy is lost, but our reset rules don't seem to work.
1. We verified if some emails were blocked on the mail server, but according to the people responsible for this service - that's not the case.
2. I found this article and thought maybe there's an issue with the notification service in general.
3. Alarm rules work just fine - we get email notifications (as written above).
4. We didn't change anything in Network connectivity lostReset rules except enabling SNMP traps and Send email notifications option and setting the proper email address.
When we go to a particular host and look at the Events we have the following set of events:
So there's no email notification after Network uplink redundancy lost changes from Red to Green.
We're wondering if this might have to do with the notification service itself.
