Zabbix Proxy collected data incorrect time on some instances.

[[email protected]]

I have been having issues with my Zabbix proxy of late. After some time, the zabbix proxy stops receiving/getting data, everything queues up until I restart the zabbix-proxy service, the queue then drops and everything works normally. I have done tail -f of both zabbix-proxy.log and zabbix-server.log, but could not see much. I did discover that the zabbix proxy data does come from a future date on some of the instances as per the image.
I am lost as I don't know what to do and this has been working so well for months. I have created a new sql database on the zabbix-proxy hoping that it might fix it.

Configure time synchronization on the proxy and on the server!
In your case, it is very likely that the proxy periodically receives the wrong time "in the future" and starts transmitting data to the server with the wrong date. Then the time on the proxy is corrected but the data transmitted to the server is not saved because there is already "newer" data in the database.
If the proxy is installed on the VM, check the hypervisor time / if on hardware, check the BIOS time.
