Best plugin for tracking Apache response codes with Munin

apache-2.2munin

I'd like to monitor the rate of 404, 403, 500 etc errors in my Apache logs with Munin but I can't find a plugin to do this. Surely it exists?

Best Answer

Here's a plugin that might help. It monitors various request codes by parsing the log files.

https://github.com/dc2447/munin-apache-error-rate/blob/master/apache_error_rate

Near the top you can set the codes you care about:

mystatuscodes="400 401 403 404 500 503 504"

You can also configure how many recent log lines it looks at and what log file to parse.

To be honest you are probably better off writing your own plugin. It's really simple and you can customize it for your needs (for example, does your system use logrotate? etc.) – plus, you get to write your first munin plugin.

mod_status already does that for you. You just have to make sure to use ExtendedStatus. To see an example how it'd look like, refer to apache.org's server-status page.

Nginx – Monitoring Nginx vhosts with Munin

I would expect the munin plugin require's nginx's status module. This is not compiled in by default, nor is it automatically made available even when it is compiled in.

Compile nginx with the --with-http_stub_status_module flag.

Make sure you've enabled stub status inside a server {} block like this:

    location /nginx_status {
            stub_status on;
            access_log off;
    }

Restart nginx so that your changes take effect.

curl http://yourdomain.example.com/nginx_status to verify nginx is in fact returning data.

Make sure munin knows the full path to your nginx_status URL.
