# This is a simple script which will output a single line of info, and exit
|
||
|
|
# with a return code which indicates status of a given Rattail daemon. It was
|
||
|
|
# designed for use with Shinken monitoring. Invoke like so:
|
||
|
|
#
|
||
|
|
# check-rattail-daemon NAME
|
||
|
|
#
|
||
|
|
# Where NAME refers to the service, e.g. 'rattail-datasync'. Exit code may be:
|
||
|
|
#
|
||
|
|
# * 0 = daemon is confirmed running
|
||
|
|
# * 2 = daemon is confirmed *not* running
|
||
|
|
# * 3 = unknown state
