Hi everyone,
 
Does anyone know if there are any attributes or metrics for the UNIX agent applications, in particular NGINX, MySQL, Apache, and PowerDNS Recursor. I'm looking to create some alert checkers for them if it's at all possible.
 
The only information I can find about the attributes and metrics is the following:
 
http://www.observium.org/docs/attribs_metrics/

Regards,
Alex.
