Need help on running combination of Nagios, Nconf, Nagiosgraph


I am new to Nagios and I am having problem to put all this applications together. I have very limited knowledge of all this tools and availability, so I need experts help on this. Here are the steps that I went thru:

I installed Nagios in one of my Linux server.

In the same machine but different directory I Installed Nconf to add about 70 hosts with about five services for each hosts. I have to add about 200 more hosts.

I used CSV (comma-separated values) file to store the data.

Now, I need graph so I installed Nagiosgraph and I am trying to make it work since last two weeks, but it is not working. When I reload nagios, it runs fine and I see the icon to brows to the graph, but when I click on it, I get following error:

(Server error!
The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there was an error in a CGI script. )
If you think I didn't select right tool to add hosts and for graph, what is better tools to add bunch of servers and to get the graphs. I also have some switches to monitor too.

Did you follow the installation guide? Post your related config file.

Question add and manage nagios database, nagiosgraph

Thanks for reply quanta,

Yes I did follow the nagiosgraph installation guide. The problem is that guide is for if database about host with .cfg files in the nagios by itself but in my case, all .cfg files are coming from the Nconf where I added about 100 hosts.

What tool do you use to add the hosts and services to nagios. I am sure people are not adding and managing it manually.

My nagiosgraph.conf file:

# Author: (c) 2010 Matthew Wall

# Location of nagiosgraph log file. Debug output ends up here.
logfile = /var/opt/nagiosgraph/nagiosgraph.log

# Optionally keep logging from CGI scripts in a separate file.
#cgilogfile = /var/log/nagiosgraph-cgi.log

# Location of nagios performance data log file. Comment out if not used.
#perflog = /usr/local/nagios/perfdata.log

# Directory to store rrd database files
rrddir = /var/opt/nagiosgraph/rrd

# File containing regular expressions to identify service and perf data
mapfile = /opt/nagiosgraph/map

# Nagiosgraph CGI URL.
nagiosgraphcgiurl = /nagiosgraph/

# Nagios CGI URL. If the Nagiosgraph CGI scripts are in a directory other
# than the Nagios CGI directory, then specify the Nagios CGI URL here.
nagioscgiurl = /nagios/cgi-bin

# JavaScript: URL to the nagiosgraph javascript file.
javascript = /nagiosgraph/nagiosgraph.js

# Stylesheet: URL to the nagiosgraph stylesheet.
stylesheet = /nagiosgraph/nagiosgraph.css

nagios.cfg 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!!!


# These are the object configuration files in which you define hosts,
# host groups, contacts, contact groups, services, etc.
# You can split your object definitions across several config files
# if you wish (as shown below), or keep them all in a single config file.

# You can specify individual object config files as shown below:

@tina2010: I add hosts and services manually because I manage only about 30 servers.

I'm not familiar with Nconf and nagiosgraph (I use PNP4Nagios) but did you look at the nagios and Apache log?
