How to resolve the issue when Zabbix graph monitoring doesn’t show any data?
If data is not displayed on Zabbix graph monitoring, you can try the following methods to solve the issue:
- Verify if the host or network device has been successfully added to Zabbix monitoring and that the corresponding monitoring items have been enabled.
- Check if the network connection between the Zabbix server and the monitored host is working properly. You can use the ping command to test the network connection between the hosts.
- Verify if the monitoring items are correctly configured. Check if the keys, types, and applications of the monitoring items are correct.
- Check the clock synchronization between the Zabbix server and monitored hosts to ensure their time is synchronized.
- Check the log files of the Zabbix server to see if there are any related errors or warning messages.
- Check if the Zabbix Agent process is running on the monitored host by using the ps command to verify its existence.
- Check the firewall settings on the monitored host to ensure that the communication port for the Zabbix Agent (default is 10050) is open.
- Make sure that the Zabbix Agent is properly configured and matches the IP address and port number of the Zabbix server.
If the above methods still fail to resolve the issue, you can further investigate the log files of both the Zabbix server and monitored hosts to diagnose and solve the problem by looking for error or warning messages.
