This plugin is a wrapper for the check_nt command and NC_Net client provided by ShatterIT. The NC_Net client supports an ENUMPROCESS option but the default check_nt command does not. In combination with the modified check_nt and the NC_Net client, you can open up monitoring of your Windows Servers.
From the script itself:

This plugin uses the modified version of check_nt to
count the instances of a specific process running on a
Windows server.

This plugin relied on two specific pieces to work properly
if at all:
NC_Net (http:// on the client
check_nt (

Both of these are fully compatible replacements for NSClient
and the default check_nt shipped with nagios plugins

If you wish to keep the original check_nt and compile the
ShatterIT version as a different plugin,
we give the option of defining where to find that plugin.

In our enviroment, we have a process that we spawn multiple instances of on a single machine. This is useful if you have a third-party application that can only support a fixed amount of memory.

We want to make sure that:

1) The minimum number of instances of a given process are running.
2) A warning is generated if more than the expected number are running so that an operator can investigate and escalate if needed.
