[SOLVED] How to get the graphs working

[dobebo]

Hi everybody,

I am new to Oreon and Nagios. Everything works fine, except to one thing. I can't get no graphs on the Interface and the Howto gives no Information about this thing. Maybe some of you know how to get this stuff working.

I would be very glad about any help

Thanks

Welcome dobedo,

You need rrdtool (1.2 will support in RC3 ) install.
You must specify path for rrd generation and validate right on this. (default /usr/local/oreon/rrd/). Nagios must be enable to write in, and apache to read in.

You must use 'check_graph_*' plugins.
Verify check_command syntax :
$USER1$/check_graph_traffic.pl -H $HOSTADDRESS$ -i $ARG1$ -w $ARG2$ -c $ARG3$ -C $ARG4$ -v $ARG5$ -g -S $ARG6$
You don't need to specify last argument ($ARG6$) in 'check_command_argument' :
!3!75!90!public!1

You can try to execute plugin in nutshell with nagios user

you can find some modified plugins with debug information here (http://wistof.free.fr) (in french only, sorry :( )

Thank you for your help wistof
I forget to mention
that my problem is not the configuration, my problem is actually that oreon shows me broken images, every time I want to see the graphs.
I am using the default rrd directory (under /usr/local/oreon/rrd/),
there are files like 7.rrd but no gif or png that can be displayed.
Where do I find them or how do I create them ?
The rights for nagios and www-data are correct.

Thanks
dobebo

that's is your rrdtool version ?

check your apache log too....

[dobebo]

rrdtool Version: 1.0.49-1

Apache error.log says

ERROR: invalid color def format
ERROR: invalid color def format
ERROR: invalid color def format
ERROR: invalid color def format
ERROR: invalid color def format

ERROR: invalid color def format

[wistof]

could you edit setting for graph (with tool img) and validate color

[dobebo]

how can I do this ?

I already edited the color settings under Basic Configuration and Data Source.

Is there another tool to do so ?

[wistof]

did you respect hexa format ? 'FFFFFF'

you could try to debug rrdtool command by edit 'graph_image.php' and add :
function rrdtool_execute($command_line, $oreon) {
$command_line = str_replace(";", "", $command_line);
print $command_line . "
";
$fp = popen($oreon->optGen->get_rrd_pwd() . escape_command(" $command_line"), "r");
return fpassthru($fp);
}

[dobebo]

nothing changed

oh, sorry... right click on broken image, and 'view image' (on firefox)

I changed the

--color BACK#white

to #FFFFFF

nothing happens. There is still this broken Image shit and if I try to open the Traffic Map I get a

The requested URL /oreon/include/trafficMap/png/trafficMap1.png was not found on this server.

I have no idea how I get this shit to work
The Plugin works fine (so says Nagios)
but there is no gif or png file generated. Are there any libraries needed or some configurations checked ?

I am no rrdtool expert also :)

trafficmap is a other thing, it's a other problem :D

[dobebo]

no, not on the command line. In the config for the graph

[wistof]

if you don't disable 'print' line in 'graph_image.php', you will contine to have broken img

[dobebo]

IT WORKS !!!

I deleted the print line and it works !!!

[wistof]

great !!!
