nscp <context or alias> [options] [-- [module options]]

client Act as a client. (think check_nrpe)
Usually aliases we can use instead.

settings Work with configuration
test Find errors and problems
unit Run unit test scripts
Aliases
lua

python Run python scripts
nrpe Think check_nrpe
nsca Think send_nsca
sys

wmi
WMI front end
eventlog Add event log message from command line
Settings (Configuration)
nscp settings --help
nscp settings --add-missing --generate [--load-all]
Will update your configuration with ALL keys
nscp settings --add-missing --activate-module <module>
Great way to "enable a new module“
nscp settings --remove-defaults --generate
Will remove all default keys/sections
nscp settings --validate
Show problems with the settings file
check_nrpe
nscp nrpe -- --help
The -- is important
nscp nrpe -- -H 127.0.0.1 -c foo -a foo bar
Execute nrpe query from nsclient++
0.4.2 will introduce:
nrpe_client -H 127.0.0.1 -c foo -a foo bar
