If you’re having trouble monitoring with the mackerel-plugin-apache2 plugin, the problem may correspond to one or more of the following issues.

• The mod_status is not set correctly.
• The URL that the plugin references and the URL assigned by the mod_status server-status handler are different.
• mod_rewrite is redirecting to an HTTPS URL etc.

Check and see whether or not any of these cases apply to you and if the server-status response is correct on the host.

You can use the following curl command to check.

curl -v http://127.0.0.1:1080/server-status

• This method can be used if Apache is configured based on the plugin’s README.
• Set up your apache server - mackerel-plugin-apache2
• If the port number etc. has been changed, please check according to your environment.
