Hi All,
Just wondering, am I the only one who has weird stuff with server - agent reachability?
Receiving many emails like:
Subject: <host>: PROBLEM, Zabbix agent on <host> is unreachable for 5 minutes
Message:
Agent ping (<host>:agent.ping): Up (1)
Original event ID: 187879
Time: 14:27:00
---------
10 seconds later would be another one:
Subject: <host>: OK, Zabbix agent on <host>is unreachable for 5 minutes

Network is good, no problem with connectivity, no errors on switch port, other services work fine.
Zabbix Server data:
