Zabbix plug in not working

Zabbix plugin installs fine but nothing happens when I try to open the grafana homepage. Below is the httpd trace. (changed the IP addr).

What is that I am doing wrong?

I don’t see any errors in the logs. What do you mean by “but nothing happens”? Are you not getting data or are you getting an error? When you configure the data source is the “Save and Test” button working?

after installating Zabbix plugin, the “Configure and Test” button works. But when try to launch Grafana page, http://localhost/zabbix/api_jsonrpc.php", screen remains blank. Httpd error logs do not show any errors. Tried using firefox on Windows and Linux.

Do you mean this plugin:

Not sure what you mean by http://localhost/zabbix/api_jsonrpc.php, Grafana is not built on PHP.

Here is an example of the Zabbix plugin:

I believe that that zabbix plugin demo page and the plugin are one and the same. Zabbix is written in php, probably thats why the call to php.

This sentence confused me. You mean Grafana is making a call to http://localhost/zabbix/api_jsonrpc.php? The log file snippet is not a Grafana log file. Is the problem with Grafana or with your Zabbix instance?
