Can anyone please list examples of how to install and configure percona plugins in nagios. I was not able to find a good example so far on any website. I am new to percona and nagios so it will be very helpful for me if you provide some detailed steps to configure percona plugin in nagios.

Hello! You are getting this most likely because Nagios can’t access this path /var/run/mysqld/mysqld.pid.  
If you run the command manually, it works, right?  
This is usually happen on Debian/Ubuntu.  
You can try to add nagios user into mysql group for example.
