-# EXTERNAL COMMAND CHECK INTERVAL
-# This is the interval at which Nagios should check for external commands.
-# This value works of the interval_length you specify later. If you leave
-# that at its default value of 60 (seconds), a value of 1 here will cause
-# Nagios to check for external commands every minute. If you specify a
-# number followed by an "s" (i.e. 15s), this will be interpreted to mean
-# actual seconds rather than a multiple of the interval_length variable.
-# Note: In addition to reading the external command file at regularly
-# scheduled intervals, Nagios will also check for external commands after
-# event handlers are executed.
-# NOTE: Setting this value to -1 causes Nagios to check the external
-# command file as often as possible.

# EXTERNAL COMMAND FILE
# This is the file that Nagios checks for external command requests.
# It is also where the command CGI will write commands that are submitted
-# EXTERNAL COMMAND BUFFER SLOTS
-# This settings is used to tweak the number of items or "slots" that
-# the Nagios daemon should allocate to the buffer that holds incoming
-# external commands before they are processed. As external commands
-# are processed by the daemon, they are removed from the buffer.
+# QUERY HANDLER INTERFACE
+# This is the socket that is created for the Query Handler interface

+# CURRENT STATES LOGGING OPTION
+# If you don't want Nagios to log all current host and service states
+# after log has been rotated to the main log file, you can disable this
+# option by setting this value to 0. Default value is 1.

# EXTERNAL COMMANDS LOGGING OPTION
# If you don't want Nagios to log external commands, set this value

-# This is the number of seconds to sleep between checking for system
-# events and service checks that need to be run.

# TIMEOUT VALUES
# These options control how much time Nagios will allow various
# types of commands to execute before killing them off. Options
# Performance data is only written to these files if the
# enable_performance_data option (above) is set to 1.

# HOST AND SERVICE PERFORMANCE DATA PROCESS EMPTY RESULTS
-# THese options determine wether the core will process empty perfdata
+# These options determine wether the core will process empty perfdata
# results or not. This is needed for distributed monitoring, and intentionally
# turned on by default.
# If you don't require empty perfdata - saving some cpu cycles
-
-# P1.PL FILE LOCATION
-# This value determines where the p1.pl perl script (used by the
-# embedded Perl interpreter) is located. If you didn't compile
-# Nagios with embedded Perl support, this option has no effect.
-
-p1_file=/usr/sbin/p1.pl
-

-
-# EMBEDDED PERL INTERPRETER OPTION
-# This option determines whether or not the embedded Perl interpreter
-# will be enabled during runtime. This option has no effect if Nagios
-# has not been compiled with support for embedded Perl.
-# Values: 0 = disable interpreter, 1 = enable interpreter

-
-# EMBEDDED PERL USAGE OPTION
-# This option determines whether or not Nagios will process Perl plugins
-# and scripts with the embedded Perl interpreter if the plugins/scripts
-# do not explicitly indicate whether or not it is okay to do so. Read
-# the HTML documentation on the embedded Perl interpreter for more
-# information on how this option works.

# ILLEGAL OBJECT NAME CHARACTERS
# This option allows you to specify illegal characters that cannot
# be used in host names, service descriptions, or names of other
# This option determines whether or not Nagios will make all standard
# macros available as environment variables when host/service checks
# and system commands (event handlers, notifications, etc.) are
-# executed. Enabling this option can cause performance issues in
-# large installations, as it will consume a bit more memory and (more
-# importantly) consume more CPU.
-# Values: 1 - Enable environment variable macros (default)
-# 0 - Disable environment variable macros
+# executed.
+# Enabling this is a very bad idea for anything but very small setups,
+# as it means plugins, notification scripts and eventhandlers may run
+# out of environment space. It will also cause a significant increase
+# in CPU- and memory usage and drastically reduce the number of checks
+# you can run.
+# Values: 1 - Enable environment variable macros
+# 0 - Disable environment variable macros (default)
