Newish to zabbix. Not new to linux. I set up a Zabbix server and 2 proxy servers to monitor the control systems network at my workplace. The master server, postgres database, and front-end all run in docker containers on a dedicated server inside our DMZ. The two proxies run on real hardware inside the two control networks. Until last Friday, this setup was working well. I have been using Grafana as a front-end to set up some custom dashboards. In the process of changing grafana to use a postgres back-end, I ended up spawning a new postgres server on the same docker network pointing to the same directory as my zabbix back-end server. This caused some data loss since the zabbix server could not keep a connection alive since the new server believed itself to be a zabbix server as well. After realizing my mistake, I took down the new server and moved it to its own data directory and subnet. I then had to run a reindex on the zabbix database to clean up some transactions which had been cutoff part way through processing. After this, all seemed happy again. However, now I do not get data on all items anymore. Instead, I get clients which are enabled and show supported, but have no data, or agents such as the one in the attached screenshot where I have some data, but not all. These items were working before, and I can manually use the test page to pull the data. I don't want to start over if possible as the system has about 150 devices monitored with several custom templates. In fact, the grafana configuration was so I could make the system live for users other than myself. Has anyone seen this problem before or any idea where to start? Nothing in the proxy, server, or postgres logs that I can see.
