The problem is old.... has been an issue for many many months, but there is no respons, or solution, on this forum :-(

I am just waiting for 1.6 .... If it ever comes... :-)

New guy here. Hi all.

I did some experimenting and what I've found is that the configuration process after the first boot is where the errors are introduced.

In the file

Code: Select all

/usr/local/nagios/nagiosgraph/etc

(post configure) are these definitions at the top of the file:

Code: Select all

logfile = /var/nagiosgraph/nagiosgraph.log
cgilogfile = /var/nagiosgraph/nagiosgraph-cgi.log
perflog = /var/nagios/perfdata.log
rrddir = /var/nagiosgraph/rrd
mapfile = /etc/nagiosgraph/map
nagiosgraphcgiurl = /nagiosgraph/cgi-bin
javascript = /nagiosgraph/nagiosgraph.js
stylesheet = /nagiosgraph/nagiosgraph.css

These are the problems. The actual values for what I've found so far should be:

Code: Select all

logfile = /usr/local/nagios/nagiosgraph/var/nagiosgraph.log
cgilogfile = /usr/local/nagios/nagiosgraph/var/
perflog = /usr/local/nagios/var/perfdata.log
rrddir = /usr/local/nagios/nagiosgraph/var/rrd
mapfile = /usr/local/nagios/nagiosgraph/etc/map

And I figured out that the javascript and stylesheets files are in the directories that are links as shown below.

Code: Select all

/var/www/html/share/nagios -> /var/www/html/share/nagios_themes/nems-1.3
/var/www/html/share/nagios3 -> /var/www/html/share/nagios_themes/nems-1.3
/var/www/html/share/nagios_themes

I tried patching it (patch file below) and only fixed some of it. I've run out of time for working on it for the next couple of weeks and I'm hoping someone can add to what I've done here.

That's it from me for now. I've gotta run.

Thanks for everyone's hard work on this.

Cool, thanx :-)
I will try these changes and see what happens :-)

Damm, even I am having a similar kind of issue, I have searched all over the internet and even have posted io games on the number of threads on a different forum, no solution seems to work. I am really frustrated, can anyone of you here help me resolve this issue, I am very much tired now.

I haven't found a solution and is (still) waiting for an update from 1.5.2 or a fix :-(
