# Sample NRPE Config File
|
||||
# Written by: Ethan Galstad (nagios@nagios.org)

#
|
||||
# Last Modified: 11-23-2007
|
||||
#
|
||||
# NOTES:
|
||||
# This is a sample configuration file for the NRPE daemon. It needs to be
|
||||
# located on the remote host that is running the NRPE daemon, not the host
|
||||
# from which the check_nrpe client is being executed.

#
|

# Note: The daemon only does rudimentary checking of the client's IP

# COMMAND ARGUMENT PROCESSING
|
||||
# This option determines whether or not the NRPE daemon will allow clients
|
||||
# to specify arguments to commands that are executed. This option only works
|
||||
# if the daemon was configured with the --enable-command-args configure script
|
||||
# option.
|

#
|

# *** ENABLING THIS OPTION IS A SECURITY RISK! ***

# Read the SECURITY file for information on some of the security implications
|

# of enabling this variable.

# COMMAND PREFIX
|
||||
# This option allows you to prefix all commands with a user-defined string.
|
||||
# A space is automatically added between the specified prefix string and the
|
||||
# command line from the command definition.
|
||||
#
|
||||
# *** THIS EXAMPLE MAY POSE A POTENTIAL SECURITY RISK, SO USE WITH CAUTION! ***
|
||||
# Usage scenario:
|
||||
# Execute restricted commmands using sudo. For this to work, you need to add
|
||||
# the nagios user to your /etc/sudoers. An example entry for alllowing
|
||||
# execution of the plugins from might be:
|
||||
#
|
||||
# nagios ALL=(ALL) NOPASSWD: /usr/lib/nagios/plugins/
|
||||
#
|
||||
# This lets the nagios user run all commands in that directory (and only them)
|
||||
# without asking for a password. If you do this, make sure you don't give
|
||||
# random users write access to that directory or its contents!

# DEBUGGING OPTION

# syslog facility.

# Values: 0=debugging off, 1=debugging on
|
||||
|
||||

# COMMAND TIMEOUT

# allow plugins to finish executing before killing them off.

# CONNECTION TIMEOUT
|
||||
# This specifies the maximum number of seconds that the NRPE daemon will
|
||||
# wait for a connection to be established before exiting. This is sometimes
|
||||
# seen where a network problem stops the SSL being established even though
|
||||
# all network sessions are connected. This causes the nrpe daemons to
|
||||
# accumulate, eating system resources. Do not set this too low.

# WEEK RANDOM SEED OPTION
|
||||
# This directive allows you to use SSL even if your system does not have
|
||||
# a /dev/random or /dev/urandom (on purpose or because the necessary patches
|
||||
# were not applied). The random number generator will be seeded from a file
|
||||
# which is either a file pointed to by the environment valiable $RANDFILE
|
||||
# or $HOME/.rnd. If neither exists, the pseudo random number generator will
|
||||
# be initialized and a warning will be issued.
|
||||
# Values: 0=only seed from /dev/[u]random, 1=also seed from weak randomness

# INCLUDE CONFIG FILE

#include=<somefile.cfg>

|

# INCLUDE CONFIG DIRECTORY

# COMMAND DEFINITIONS
|
||||
# Command definitions that this daemon will run. Definitions
|
||||
# are in the following format:
|
||||
#
|
||||
# command[<command_name>]=<command_line>
|
||||
#
|
||||
# When the daemon receives a request to return the results of <command_name>
|
||||
# it will execute the command specified by the <command_line> argument.
|
||||
#
|
||||
# Unlike Nagios, the command line cannot contain macros - it must be
|
||||
# typed exactly as it should be executed.
|
||||
#
|
||||
# Note: Any plugins that are used in the command lines must reside
|
||||
# on the machine that this daemon is running on! The examples below
|
||||
# assume that you have plugins installed in a /usr/local/nagios/libexec
|
||||
# directory. Also note that you will have to modify the definitions below
|
||||
# to match the argument format the plugins expect. Remember, these are
|
||||
# examples only!
|
||||
|
||||
|
||||
# The following examples use hardcoded command arguments...
|
||||
|
||||
command[check_users]=/usr/lib64/nagios/plugins/check_users -w 5 -c 10
|
||||
command[check_load]=/usr/lib64/nagios/plugins/check_load -w 15,10,5 -c 30,25,20

command[check_hda1]=/usr/lib64/nagios/plugins/check_disk -w 20% -c 10% -p /dev/hda1

|

|

|

# The following examples allow user-supplied arguments and can
|
||||
# only be used if the NRPE daemon was compiled with support for
|
||||
# command arguments *AND* the dont_blame_nrpe directive in this
|

# config file is set to '1'. This poses a potential security risk, so
