# # 'check_database_size' command definition

#         command_name    check_diff_db_sec
#         command_line    $USER1$/check_by_ssh -H $HOSTADDRESS$ -l nagios -t 20 -C "scripts/check_diff_db_sec -i '$ARG1$' -d '$ARG2$'"

# define service{
#         host_name               db2sever
#         service_description     Database security
#         check_command           check_diff_db_sec!/home/db2inst1!sample
#         use                     generic-service
# }
#
# When using NRPE:
#
# In the database server:
#
# command[check_diff_db_sec]=/home/nagios/scripts/check_diff_db_sec -i /home/db2inst1 -d sample
#
# Then modify the path according to your script location, instance home dir,
# database, refresh rate and thresholds.
#
# In the Nagios server:
#
# define service{
#         host_name               db2server
#         service_description     Database security
#         check_command           check_nrpe_1arg!check_diff_db_sec
#         use                     generic-service
# }
#
# Parameters:
# -d | --database : Database name.
# -D | --directory : Directory to create the history (Default is /tmp)
# -h | --help : Show the help of this script.
# -i | --instance : Home directory of the instance. Usually it is
#   /home/db2inst1.
# -K | --mk : Change the output for Check_MK.
# -T | --trace : Trace mode. Writes output in /tmp.
# -v | --verbose : Execute the program in verbose mode.
# -V | --version : Show the current version of this script.
#
# In AIX, the long name options are not supported.
#
# The exit codes are the standard for Nagios.
#
# 0 The plugin was able to check the service and it appeared to be functioning
#   properly.
# 1 The plugin was able to check the service, but it appeared to be above some
#   "warning" threshold or did not appear to be working properly.
# 2 The plugin detected that either the service was not running or it was above
#   some "critical" threshold.
# 3 Invalid command line arguments were supplied to the plugin or low-level
#   failures internal to the plugin (such as unable to fork, or open a tcp
#   socket) that prevent it from performing the specified operation.
#   Higher-level errors (such as name resolution errors, socket timeouts, etc)
#   are outside of the control of plugins and should generally NOT be reported
#   as UNKNOWN states.
