What are the causes of communication failure with zabbix agent on a Windows host?
Among many Windows servers, there is one that works with the database of various applications. On this one, every day from midnight to one in the morning there are communication failures with Zabbix Agent.
The zabbix_server.log log points messages to several items: failed: 'first network error, wait for 15 seconds', 'connection restored'. The graphics are fragmented. But in zabbix_agentd.log no error message appears or the Agent has restarted, nothing.
I saw that just before stopping collecting data Free Memory remained stable, there was no significant increase for Number of threads, nor a sharp increase in network traffic.
Now I think about turning on Windows service discovery to see if any services might be disrupting communication with Zabbix Agent. What do you think? What else should I see?
