SSH Server
While u can use "check_by_ssh" plugin, it will - for every service check open
a new SSH connection to a host, which is quite an overhead for both the host and the monitoring server
SSH Server consists of two parts, one the server.pl the other the command.pl
Basically its a connection caching SSH proxy
It successfully runs 3000 service checks on 200 hosts with an avg check_interval of 10mins, and can probably handle much more.

I used this programs for a while. It's working well at first, and give a headache later.
The story is that I sometimes saw that all the server.pl processes are doing nothing, and Nagios sent notifications for each service with UNKNOWN status.
Later I figured out that whenever the network is down, all the server.pl processes lost connection but still running. When the network comes back up, those processes cannot gain the connections.
