# Puts important device information (machine type, serial number, etc)
# along with deployment-specific checks (bladecenter chassis, collected
# out of band and checks for certain expected configuration) and outpusts
# it all with an exit code that Nagios understands

# We want to know in nagios if certain configuration properties
# are present, and if they are enabled.  Certain combinations are concerning,
# but we only want to know -- these are test devices and not production.

# Here's an example of a config block that we're checking for:
# _config_IncludeConfig_net_mAdminState="enabled"
# _config_IncludeConfig_net_URL="config:dp521-net.cfg"
# _config_IncludeConfig_net_OnStartup="on"
# _config_IncludeConfig_net_InterfaceDetection="off"
