Hello:
We have zabbix server 1.8.10 on a CentOS 5.9 host.
We have 76 hosts in 9 host groups. (This doesn't include the zabbixserver in the zabbixserver group)
We have an [email protected] media that is present in all our Actions. One to the client and one to us.
Those all are working.
The ones we have labeled "c9Internal" were noticed today not to be sending. These only have one media - [email protected]
We moved some servers from one grid to another. I changed the hosts' IP to point to the new ones. One server did not get migrated and remained on the old host.
I enabled this group of hosts after making the changes and the one left on the old host showed up in the Dashboard as having issue but no action/alert is ever sent. This is when this issue became apparent.
I have taken a client's working Action and cloned it and removed their media and assigned it an "AND / OR (A) and (B)" Action condition with the following criteria:
Trigger value = "PROBLEM"
Host group = "c9Internal"
But this problem persists.
Some interesting issues I notice in the zabbix_server.log are:
Almost 8000 of these entries for these 2 hosts.
Those are very old hosts I used way back in the day when I originally started setting up this server. and...
and haven't seen any further "MySQL server has gone away" message in the server.log since rebooting.
I thought maybe it was the "internal" designation in the identifier, so I moved our hosts to a "Test" group and altered the action but it didn't make any difference.
I've tried adding new individual media to our actions and even a foreign non work-related email host. None is ever received.
Can anyone shed some light on what may be causing this or some additional troubleshooting steps I may take to resolve this?
I'd sure appreciate it.
Thank you for your time.
