EVENT BROKER MODULE(S)

# This directive is used to specify an event broker module that should
# by loaded by Nagios at startup. Use multiple directives if you want
# to load more than one module. Arguments that should be passed to
# the module at startup are seperated from the module path by a space.
#
# Example:
#
# nebmodule=<modulepath> [moduleargs]

# to 1.

log_event_handlers=1

INITIAL STATES LOGGING OPTION

# If you want Nagios to log all initial host and service states to
# the main log file (the first time the service or host is checked)
# you can enable this option by setting this value to 1. If you
# are not using an external application that does long term state
# statistics reporting, you do not need to enable this option. In
# this case, set the value to 0.

log_initial_states=0

EXTERNAL COMMANDS LOGGING OPTION

# If you don't want Nagios to log external commands, set this value
# to 0. If external commands should be logged, set this value to 1.
# Note: This option does not include logging of passive service
# checks - see the option below for controlling whether or not
# passive checks are logged.

log_external_commands=1

PASSIVE CHECKS LOGGING OPTION

log_passive_checks=1

GLOBAL HOST AND SERVICE EVENT HANDLERS

# These options allow you to specify a host and service event handler
# command that is to be run for every host or service state change.
# The global event handler is executed immediately prior to the event
# handler that you have optionally specified in each host or
# service definition. The command argument is the short name of a
# command definition that you define in your host configuration file.

SERVICE INTER-CHECK DELAY METHOD

# This is the method that Nagios should use when initially
# "spreading out" service checks when it starts monitoring. The
# default is to use smart delay calculation, which will try to
# space all service checks out evenly to minimize CPU load.
# Using the dumb setting will cause all checks to be scheduled
# at the same time (with no delay between them)! This is not a
# good thing for production, but is useful when testing the
# parallelization functionality.
# n = None - don't use any delay between checks

# program start time that an initial check of all services should
# be completed. Default is 30 minutes.

max_service_check_spread=30

SERVICE CHECK INTERLEAVE FACTOR

# This variable determines how service checks are interleaved.
# Interleaving the service checks allows for a more even
# distribution of service checks and reduced load on remote
# hosts. Setting this value to 1 is equivalent to how versions
# of Nagios previous to 0.0.5 did service checks. Set this
# value to s (smart) for automatic calculation of the interleave
# factor unless you have a specific reason to change it.
# s = Use "smart" interleave factor calculation
# x = Use an interleave factor of x, where x is a
# number greater than or equal to 1.

max_host_check_spread=30

MAXIMUM CONCURRENT SERVICE CHECKS

# This option allows you to specify the maximum number of
# service checks that can be run in parallel at any given time.
# Specifying a value of 1 for this variable essentially prevents
# any service checks from being parallelized. A value of 0
# will not restrict the number of concurrent checks that are

service_reaper_frequency=10

AUTO-RESCHEDULING OPTION

# This option determines whether or not Nagios will attempt to
# automatically reschedule active host and service checks to

# PERFORMANCE, RATHER THAN INCREASE IT, IF USED IMPROPERLY

auto_reschedule_checks=0

AUTO-RESCHEDULING INTERVAL

# This option determines how often (in seconds) Nagios will

# WARNING: THIS IS AN EXPERIMENTAL FEATURE - IT CAN DEGRADE
# PERFORMANCE, RATHER THAN INCREASE IT, IF USED IMPROPERLY

auto_rescheduling_interval=30

AUTO-RESCHEDULING WINDOW

# This option determines the "window" of time (in seconds) that
# Nagios will look at when automatically rescheduling checks.
# Only host and service checks that occur in the next X seconds
# (determined by this variable) will be rescheduled. This option
# only has an effect if the auto_reschedule_checks option is
# enabled. Default is 180 seconds (3 minutes).
# WARNING: THIS IS AN EXPERIMENTAL FEATURE - IT CAN DEGRADE

# events and service checks that need to be run.

sleep_time=0.25

TIMEOUT VALUES

# These options control how much time Nagios will allow various

RETAIN STATE INFORMATION

# This setting determines whether or not Nagios will save state
# information for services and hosts before it shuts down. Upon
# startup Nagios will reload all saved service and host state
# information before starting to monitor. This is useful for
# maintaining long-term data on state statistics, etc, but will

# a one-time penalty, I think its well worth the additional
# startup delay.

retain_state_information=1

STATE RETENTION FILE

# This is the file that Nagios should use to store host and
# service state information before it shuts down. The state

# variable is set to 1.

state_retention_file=/usr/local/nagios/var/retention.dat

RETENTION DATA UPDATE INTERVAL

# This setting determines how often (in minutes) that Nagios
# will automatically save retention data during normal operation.
# If you set this value to 0, Nagios will not save retention
# data at regular interval, but it will still save retention
# data before shutting down or restarting. If you have disabled
# state retention, this option has no effect.

retention_update_interval=60

USE RETAINED PROGRAM STATE

# This setting determines whether or not Nagios will set
# program status variables based on the values saved in the

# value to 1. If not, set this value to 0.

use_retained_scheduling_info=0

INTERVAL LENGTH

# This is the seconds per unit interval as used in the

# that each interval is one minute long (60 seconds). Other settings
# have not been tested much, so your mileage is likely to vary...

interval_length=60

AGGRESSIVE HOST CHECKING OPTION

# If you don't want to turn on aggressive host checking features, set

# on what aggressive host check is or check out the source code in
# base/checks.c

use_aggressive_host_checking=0

SERVICE CHECK EXECUTION OPTION

# This determines whether or not Nagios will actively execute
# service checks when it initially starts. If this option is
# disabled, checks are not actively made, but Nagios can still

=somecommand

ORPHANED SERVICE CHECK OPTION

# This determines whether or not Nagios will periodically
# check for orphaned services. Since service checks are not
# rescheduled until the results of their previous execution
# instance are processed, there exists a possibility that some
# checks may never get rescheduled. This seems to be a rare

AGGREGATED STATUS UPDATES

# This option determines whether or not Nagios will
# aggregate updates of host, service, and program status
# data. Normally, status data is updated immediately when
# a change occurs. This can result in high CPU loads if
# you are monitoring a lot of services. If you want Nagios

status_update_interval=15

FLAP DETECTION OPTION

# This option determines whether or not Nagios will try
# and detect hosts and services that are "flapping".
# Flapping occurs when a host or service changes between

# group names/descriptions in some fields of various object types.
# Values: 1 = enable regexp matching, 0 = disable regexp matching

use_regexp_matching=0

"TRUE" REGULAR EXPRESSION MATCHING

# This option controls whether or not "true" regular expression
# matching takes place in the object config files. This option
# only has an effect if regular expression matching is enabled
# (see above). If this option is DISABLED, regular expression
# matching only occurs if a string contains wildcard characters
# (* and ?). If the option is ENABLED, regexp matching occurs
# all the time (which can be annoying).
