CheckSystem.dll

A module to check various system related things. A list of the modules and there potential use is listed below here.

• wiki:CheckCPU, Check CPU load
• wiki:CheckUpTime, Check system uptime
• wiki:CheckServiceState, Check state of a service
• wiki:CheckProcState, Check state of a process
• wiki:CheckMem, Check memory usage (page)

Command Line

To simplify debug and setup there is two commandline options that list and test all avalible PDH counters.

• NSClient++ -noboot CheckSystem debugpdh
• NSClient++ -noboot CheckSystem listpdh

Configuration

This module should auto detect most versions of windows (if you have a problem with this let me know so I can update it). Thus you no longer need to configure the grayed out options. There is also some other tweaks that can be configured such as check resolution and buffer size. For more details on how to configure this refer to the Configuration section.
