Hi everyone,
I am using Zabbix Cloud 7.0 to collect data from Windows workstations in a distributed environment. I am using Zabbix Agent 2 with auto registration, which is working correctly.
However, I noticed that some hosts auto register successfully, but data such as RAM, disk, and other metrics remain empty in Zabbix.
Checking the agent logs, I see recurring messages like these:
2025/03/17 16:20:29.013447 [101] cannot connect to [server-address:10051]: dial tcp: lookup server-address: no such host
2025/03/17 16:20:29.013447 [101] active check configuration update from host [BQK-TAA01] started to fail
2025/03/17 16:20:34.038266 [101] active check configuration update from [server-address:10051] is working again
2025/03/17 16:22:34.016769 [101] cannot connect to [server-address:10051]: dial tcp: lookup server-address: no such host
2025/03/17 16:22:34.017295 [101] active check configuration update from host [BQK-TAA01] started to fail
2025/03/17 16:22:39.046652 [101] active check configuration update from [server-address:10051] is working again
What I have tested so far:
- Restarted the agent service on the affected host.
- Tested connectivity to the Zabbix server from the host manually, no issues.
- Firewall does not seem to be blocking communication, since the host successfully auto registered.
- Other hosts using the same template are working correctly.
What could be causing this issue? Any suggestions for further troubleshooting?
Thanks!
