NHC Control Variables

NHC basics.

The following variables in /etc/opt/cray/nodehealth/nodehealth.conf affect the fundamental behavior of NHC.

advanced_features

If set to on, this variable allows multiple instances of NHC to run simultaneously. This variable must be on to use CNCU and reservation sets.

Default: on

dumpdon

If set to off, NHC will not request any dumps or reboots from dumpd. This is a quick way to turn off dump and reboot requests from NHC. The dump, reboot, and dumpreboot actions do not function properly when this variable is off.

Default: on

anyapid

Turning anyapid on specifies that NHC should look for any apid in /dev/cpuset while running the Application Exited Check and print stack traces for processes that are found.

Default: off
