NFS check configuration files.
Files are named NN.RPCSERVICE.check. Files without a .check suffix
are ignored.
Supported variables are:
* family - "tcp" or "udp" or space separated list
default: tcp, not used with "service_check_cmd"
* version - optional, RPC service version number
default is to omit to check for any version,
not used with "service_check_cmd"
* unhealthy_after - number of check fails before unhealthy
default: 1
* restart_every - number of check fails before restart
default: 0, meaning no restart
* service_stop_cmd - command to stop service
default: no default, must be provided if
restart_every > 0
* service_start_cmd - command to start service
default: no default, must be provided if
restart_every > 0
* service_check_cmd - command to check health of service
default is to check RPC service using rpcinfo
* service_debug_cmd - command to debug a service after trying to stop it;
for example, it can be useful to print stack
traces of threads that have not exited, since
they may be stuck doing I/O;
no default, see also function program_stack_traces()
Quoting inside values is not preserved.
