So we faced an issue earlier this week where we noticed that all our RHEL7 servers were incorrectly pointing to a RHEL6 Zabbix repo we host locally. As such, all of the agents running were the .el6 version. Oddly, it still worked (with a little bit of changes needing to be made to ownership of /var/run/Zabbix).
However, today I went about correcting the repository, replacing the RHEL6 rpms with RHEL7, and reinstalling the Zabbix agent across our RHEL7 environment. I'm in a really weird situation, now, though.
So here's what I've observed:
1) The agent is running fine, configured fine, and reporting data to the Zabbix server (as observed just at a network-traffic level). How I tested is just restarting the zabbix-agent process on a test server and seeing if it is making a network connection to the zabbix server:
2) I can zabbix_get uptime of this server as well:
3) I use Grafana to visualize the data out of Zabbix. It is still accumulating data from Zabbix. I've looked at data for the last 3 hours and there's a full set of real data being pulled in from Zabbix/MariaDB.
But when I log in to zabbix to check for alarms and such, there's nothing displayed? There used to be a lot of information. I've tried restarting the service, restarting the server, looking through zabbix server logs for any errors, looking through mariadb logs for errors, i'm getting nothing.
Any tips or ideas here are much appreciated. Thanks in advance!
