Nagiosgrapth - no graphs

Post by setevoy »

Hi.

I have installed Nagiosgraph, manually, with this two HowTos:

http://sourceforge.net/p/nagiosgraph/gi ... ee/INSTALL
http://sachinharma.blogspot.com/2013/08 ... -on_7.html

All seems work - but I haven't any real graphs:

Image

Please, pay attention - there is yellow quadrate - it's selected by mouse, and looks like - there is some "graph", but it won't display.

I have data in rrd directory:

Code: Select all

# rrdtool dump /var/nagios/rrd/www.dev.domain.com/Current%20Load___load1.rrd
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE rrd SYSTEM "http://oss.oetiker.ch/rrdtool/rrdtool.dtd">
<!-- Round Robin Database Dump -->
<rrd>
        <version>0003</version>
        <step>300</step> <!-- Seconds -->
        <lastupdate>1435935645</lastupdate> <!-- 2015-07-03 15:00:45 UTC -->

        <ds>
                <name> data </name>
                <type> GAUGE </type>
                <minimal_heartbeat>600</minimal_heartbeat>
                <min>NaN</min>
                <max>NaN</max>
...
No error in logs, etc.

In nagios.cfg:

Code: Select all

...
process_performance_data=1
service_perfdata_file=/var/log/nagios/perfdata.log
service_perfdata_file_template=$LASTSERVICECHECK$||$HOSTNAME$||$SERVICEDESC$||$SERVICEOUTPUT$||$SERVICEPERFDATA$
service_perfdata_file_mode=a
service_perfdata_file_processing_interval=30
service_perfdata_file_processing_command=process-service-graph
...
In templates.cfg:

Code: Select all

define service {
       name graphed-service
       action_url show.cgi?host=$HOSTNAME$&service=$SERVICEDESC$' onMouseOver='showGraphPopup(this)' onMouseOut='hideGraphPopup()' rel='showgraph.cgi?host=$HOSTNAME$&service=$SERVICEDESC$&period=week&rrdopts=-w+450+-j
       register 0
     }
In commands.cfg:

Code: Select all

define command {
       command_name  process-service-graph
       command_line  /bin/perl /usr/local/nagios/libexec/insert.pl
     }
And finally - in host config:

Code: Select all

define service{
        use                             local-service,graphed-service
        host_name                       www.dev.reddotsquare.com
        service_description             Tomcat mem
        check_command                   check-tomcat-mem!8080!admin!Iivoh4pe
        notifications_enabled           1
        }
What I'm doing wrong here?

One thing that comes to mind is SELinux - it's possible that it needs to be disabled for this to function properly.

Code: Select all

sestatus
No error in logs, etc.
Which logs? Did you check your apache access log?

Code: Select all

tail /var/log/httpd/access_log

Hi, @jolson

Thanks for your replay.

Code: Select all

sestatus
SELinux always disabled:

Code: Select all

# sestatus
SELinux status:                 disabled
Which logs? Did you check your apache access log?

Code: Select all

tail /var/log/httpd/access_log
And no related error in NGINX logs - neither /var/log/nginx/nagios-error.log nor /var/log/nginx/error.log.

Start a tail on the access and error logs:

Code: Select all

tail -f /var/log/httpd/error_log /var/log/httpd/access_log
Then open up the page again or refresh and post the output, there should at least be some access_log errors that will give us an indication of what is happening.

Here is all I have after opening of `Graphs` page.

Absolutely nothing in `nagios-error.log` or just NGINX's `error.log`.

The 403 there is your clue.

You either have some permissions issues on your nagiosgraph cgi or the authentication directive in your nginx config is hosed up.

ls -l /usr/local/nagios/sbin

and also share with us the location in your nginx.conf relevant to nagiosgraph.

You think - it's because of `root` owner?
I made `chown` to `nagios:nginx` - but this doesn't help.
and also share with us the location in your nginx.conf relevant to nagiosgraph.
Um.. Sorry - could you please clarify this point?

Code: Select all

GET /usr/local/nagios/sbin//showgraph.cgi
This means you're trying to get the URL "/usr/local/nagios/sbin/showgraph.cgi" - truth be told I'd suspect this means your img src URLs are wonky and that would be in the nagiosgraph config I'd suspect? Your problem reads similar to this guys:

Thanks, @jdalrymple

Problem was in my /opt/nagiosgraph/etc/nagiosgraph.conf.

There was:

Code: Select all

nagiosgraphcgiurl = /usr/local/nagios/sbin/
Instead of:

Code: Select all

nagiosgraphcgiurl = /nagios/cgi-bin
This fixed my problem.
