# Nagios plugin to check cluster synchronization process
|
||||
#
|
||||
# This check plugin is based on 3 files maintain by synchronization
|
||||
# process :
|
||||
# - status file : Empty file updated on each successfully execution
|
||||
#
|
||||
# Default : /var/run/sync_cluster.stat
|
||||
#
|
||||
# - PID file : Present only when synchronization is running and
|
||||
# contain the PID of the running process.
|
||||
#
|
||||
# Default : /var/run/sync_cluster.pid
|
||||
#
|
||||
# - Errors file : Present only when error(s) occured in previous
|
||||
# synchronizations and contains details on this error(s).
|
||||
#
|
||||
# Default : /var/run/sync_cluster.err
