Here are my benchmarks. I’m comparing a Samsung EVO (on a workstation) with a Windows 7 qemu-kvm running on my Ceph cluster.
On /etc/nagios/nrpe.cfg, (remote server) comment out the following line:

The command I used to test the connection (on the host server) is:
- /usr/lib/nagios/plugins/check_nrpe -H <remote_server_ip>
This is my on-going cheat sheet of Linux commands for my Plesk server running on CentOS 5. I will keep updating this as I go on. Read more to see the list: Continue reading…
