Could not read object configuration data!

[Sridhar Iyer]

I am facing the same issues as described in the following post:

Can you provide a link to a topic that exists that you have read through? What version of Nagios are you running, and on what distribution? Can you post your complete configuration verification output? Do you know if any changes were made before this started happening? What is the output of:

Code: Select all

ls -la /usr/local/nagios/etc/

[Sridhar Iyer]

I followed this link : http://support.nagios.com/forum/viewtop ... 33&start=0
I am using the CactiEZ.07 ISO distro from CactiEZ.
Nagios Version is 3.2.3
Did not update as the last time i updated cacti broke. So have kept the install as it is without applying updates.

output of

> ls -la /usr/local/nagios/etc/
ls: cannot access /usr/local/nagios/etc/: No such file or directory

HELP!!!!

[slansing]

We are trying to help you, we can only help properly if our questions are answered. First of all, I'd highly recommend contacting cacti as well, as you are using their distribution, and I have absolutely no idea how it is built. 2nd, when did this start happening? It had to have been after something was changed on the system. Where is your nagios configuration file, please post it here.

[Sridhar Iyer]

Well, I just installed for the first time this combined package.

I downloaded this from http://cactiez.cactiusers.org/

It has the three apps that I need for keeping a check on my Lan. Cacti , Syslog and Nagios. Till now I have been using Dude (from Mikrotik as a Nagios substitute) and Free Kiwi Logger and http://www.cacti.net/downloads/packages ... 0.8.8b.exe for graphing.

I am interested in doing away with Windows environment and getting onto Linux (of which I know very little) as the apps here seem more robust.

Umm, My Nagios Config File ... wait I root around with Webmin ....

Location of config File is /etc/nagios

and the contents are ..

##############################################################################
#
# NAGIOS.CFG - Sample Main Config File for Nagios
#
# Read the documentation for more information on this configuration
# file. I've provided some comments here, but things may not be so
# clear without further explanation.
#
# Last Modified: 11-23-2005
#
##############################################################################


# LOG FILE
# This is the main log file where service and host events are logged
# for historical purposes. This should be the first option specified
# in the config file!!!

log_file=/var/log/nagios/nagios.log



# OBJECT CONFIGURATION FILE(S)
# This is the configuration file in which you define hosts, host
# groups, contacts, contact groups, services, etc. I guess it would
# be better called an object definition file, but for historical
# reasons it isn't. You can split object definitions into several
# different config files by using multiple cfg_file statements here.
# Nagios will read and process all the config files you define.
# This can be very useful if you want to keep command definitions
# separate from host and contact definitions...

# Plugin commands (service and host check commands)
# Arguments are likely to change between different releases of the
# plugins, so you should use the same config file provided with the
# plugin release rather than the one provided with Nagios.
cfg_file=/etc/nagios/checkcommands.cfg

# Misc commands (notification and event handler commands, etc)
cfg_file=/etc/nagios/misccommands.cfg

# You can split other types of object definitions across several
# config files if you wish (as done here), or keep them all in a
# single config file.

cfg_file=/etc/nagios/minimal.cfg

#cfg_file=/etc/nagios/contactgroups.cfg
#cfg_file=/etc/nagios/contacts.cfg
#cfg_file=/etc/nagios/dependencies.cfg
#cfg_file=/etc/nagios/escalations.cfg
#cfg_file=/etc/nagios/hostgroups.cfg
#cfg_file=/etc/nagios/hosts.cfg
#cfg_file=/etc/nagios/services.cfg
#cfg_file=/etc/nagios/timeperiods.cfg

# Extended host/service info definitions are now stored along with
# other object definitions:
#cfg_file=/etc/nagios/hostextinfo.cfg
#cfg_file=/etc/nagios/serviceextinfo.cfg

# You can also tell Nagios to process all config files (with a .cfg
# extension) in a particular directory by using the cfg_dir
# directive as shown below:

#cfg_dir=/etc/nagios/servers
#cfg_dir=/etc/nagios/printers
#cfg_dir=/etc/nagios/switches
#cfg_dir=/etc/nagios/routers



# OBJECT CACHE FILE
# This option determines where object definitions are cached when
# Nagios starts/restarts. The CGIs read object definitions from
# this cache file (rather than looking at the object config files
# directly) in order to prevent inconsistencies that can occur
# when the config files are modified after Nagios starts.

object_cache_file=/var/log/nagios/objects.cache



# RESOURCE FILE
# This is an optional resource file that contains $USERx$ macro
# definitions. Multiple resource files can be specified by using
# multiple resource_file definitions. The CGIs will not attempt to
# read the contents of resource files, so information that is
# considered to be sensitive (usernames, passwords, etc) can be
# defined as macros in this file and restrictive permissions (600)
# can be placed on this file.

resource_file=/etc/nagios/resource.cfg



# STATUS FILE
# This is where the current status of all monitored services and
# hosts is stored. Its contents are read and processed by the CGIs.
# The contents of the status file are deleted every time Nagios
# restarts.

status_file=/var/log/nagios/status.dat



# NAGIOS USER
# This determines the effective user that Nagios should run as.
# You can either supply a username or a UID.

nagios_user=nagios



# NAGIOS GROUP
# This determines the effective group that Nagios should run as.
# You can either supply a group name or a GID.

nagios_group=nagios



# EXTERNAL COMMAND OPTION
# This option allows you to specify whether or not Nagios should check
# for external commands (in the command file defined below). By default
# Nagios will *not* check for external commands, just to be on the
# cautious side. If you want to be able to use the CGI command interface
# you will have to enable this. Setting this value to 0 disables command
# checking (the default), other values enable it.

check_external_commands=0



# 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.

#command_check_interval=1
#command_check_interval=15s
command_check_interval=-1



# 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
# by users, so it must be writeable by the user that the web server
# is running as (usually 'nobody'). Permissions should be set at the
# directory level instead of on the file, as the file is deleted every
# time its contents are processed.

command_file=/var/log/nagios/rw/nagios.cmd



# COMMENT FILE
# This is the file that Nagios will use for storing host and service
# comments.

comment_file=/var/log/nagios/comments.dat



# DOWNTIME FILE
# This is the file that Nagios will use for storing host and service
# downtime data.

downtime_file=/var/log/nagios/downtime.dat



# LOCK FILE
# This is the lockfile that Nagios will use to store its PID number
# in when it is running in daemon mode.

lock_file=/var/run/nagios.pid



# TEMP FILE
# This is a temporary file that is used as scratch space when Nagios
# updates the status log, cleans the comment file, etc. This file
# is created, used, and deleted throughout the time that Nagios is
# running.

temp_file=/var/log/nagios/nagios.tmp



# EVENT BROKER OPTIONS
# Controls what (if any) data gets sent to the event broker.
# Values: 0 = Broker nothing
# -1 = Broker everything
# <other> = See documentation

event_broker_options=-1



# 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:
#
# broker_module=<modulepath> [moduleargs]

#broker_module=/somewhere/module1.o
#broker_module=/somewhere/module2.o arg1 arg2=3 debug=0




# LOG ROTATION METHOD
# This is the log rotation method that Nagios should use to rotate
# the main log file. Values are as follows..
# n = None - don't rotate the log
# h = Hourly rotation (top of the hour)
# d = Daily rotation (midnight every day)
# w = Weekly rotation (midnight on Saturday evening)
# m = Monthly rotation (midnight last day of month)

# 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)

# 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

# SERVICE INTER-CHECK DELAY METHOD
# This is the method that Nagios should use when initially

# 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.

# 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

# MAXIMUM CONCURRENT SERVICE CHECKS
# This option allows you to specify the maximum number of

# 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
# to only refresh status data every few seconds, disable
# this option.
# Values: 1 = enable aggregate updates, 0 = disable aggregate updates

aggregate_status_updates=1



# AGGREGATED STATUS UPDATE INTERVAL
# Combined with the aggregate_status_updates option,
# this option determines the frequency (in seconds!) that
# Nagios will periodically dump program, host, and
# service status data. If you are not using aggregated
# status data updates, this option has no effect.

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
# states too frequently. When Nagios detects that a
# host or service is flapping, it will temporarily suppress
# notifications for that host/service until it stops
# flapping. Flap detection is very experimental, so read
# the HTML documentation before enabling this feature!
# Values: 1 = enable flap detection
# 0 = disable flap detection (default)

enable_flap_detection=0



# FLAP DETECTION THRESHOLDS FOR HOSTS AND SERVICES
# Read the HTML documentation on flap detection for
# an explanation of what this option does. This option
# has no effect if flap detection is disabled.

low_service_flap_threshold=5.0
high_service_flap_threshold=20.0
low_host_flap_threshold=5.0
high_host_flap_threshold=20.0



# DATE FORMAT OPTION
# This option determines how short dates are displayed. Valid options
# include:
# us (MM-DD-YYYY HH:MM:SS)
# euro (DD-MM-YYYY HH:MM:SS)
# iso8601 (YYYY-MM-DD HH:MM:SS)
# strict-iso8601 (YYYY-MM-DDTHH:MM:SS)
#

date_format=us



# 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/bin/p1.pl



# 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
# object types.

illegal_object_name_chars=`~!$%^&*|'"<>?,()=



# ILLEGAL MACRO OUTPUT CHARACTERS
# This option allows you to specify illegal characters that are
# stripped from macros before being used in notifications, event
# handlers, etc. This DOES NOT affect macros used in service or
# host check commands.
# The following macros are stripped of the characters you specify:
# $HOSTOUTPUT$
# $HOSTPERFDATA$
# $HOSTACKAUTHOR$
# $HOSTACKCOMMENT$
# $SERVICEOUTPUT$
# $SERVICEPERFDATA$
# $SERVICEACKAUTHOR$
# $SERVICEACKCOMMENT$

illegal_macro_output_chars=`~$&|'"<>



# REGULAR EXPRESSION MATCHING
# This option controls whether or not regular expression matching
# takes place in the object config files. Regular expression
# matching is used to match host, hostgroup, service, and service
# 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).
# Values: 1 = enable true matching, 0 = disable true matching

use_true_regexp_matching=0




# ADMINISTRATOR EMAIL ADDRESS
# The email address of the administrator of *this* machine (the one
# doing the monitoring). Nagios never uses this value itself, but
# you can access this value by using the $ADMINEMAIL$ macro in your
# notification commands.

admin_email=nagios



# ADMINISTRATOR PAGER NUMBER/ADDRESS
# The pager number/address for the administrator of *this* machine.
# Nagios never uses this value itself, but you can access this
# value by using the $ADMINPAGER$ macro in your notification
# commands.

admin_pager=pagenagios



# DAEMON CORE DUMP OPTION
# This option determines whether or not Nagios is allowed to create
# a core dump when it runs as a daemon. Note that it is generally
# considered bad form to allow this, but it may be useful for
# debugging purposes.
# Values: 1 - Allow core dumps
# 0 - Do not allow core dumps (default)

daemon_dumps_core=0

Does this help??

I am contacting the cacti users who put together this ISO to see if they can help me out as well.

Taking up from Cacti Forum, I went down to http://anarosnetwork.blogspot.in/2010/1 ... agios.html

I tried to start Nagios through the execute command option in WebMin and got this


> /etc/init.d/nagios start
nagios is stopped
runuser: warning: cannot change directory to /var/log/nagios: Permission denied
-bash: /var/log/nagios/.bash_profile: Permission denied
Starting nagios: [FAILED]

Does this help??

I think the cacti users are going to be of the most help.

[Sridhar Iyer]

Is there any walkthrough for a Nagios + Cacti + Syslog setup?? This is my requirement.
