[SOLVED] Cacti graphs not being created

[bitnoise]

Hello,

I have an issue with my graphs:

When I look at my graps (Devices > Server > Is Being Graphed (Edit)) and I click on this edit (and turn on debugging), I get this:

Code: Select all

  	 RRDTool Command:

/usr/local/rrdtool-1.2.27/bin/rrdtool graph - \
--imgformat=PNG \
--start=-86400 \
--end=-300 \
--title="SERVER - Logged in Users" \
--rigid \
--base=1000 \
--height=120 \
--width=500 \
--alt-autoscale-max \
--lower-limit=0 \
--vertical-label="users" \
DEF:a="/var/www/html/cacti/rra/server_users_26.rrd":users:AVERAGE \
DEF:b="/var/www/html/cacti/rra/server_users_26.rrd":users:MAX \
AREA:a#4668E4:"Users"  \
GPRINT:a:LAST:"Current\:%8.0lf"  \
GPRINT:a:AVERAGE:"Average\:%8.0lf"  \
GPRINT:b:MAX:"Maximum\:%8.0lf" 

RRDTool Says:

OK

Next to it I get a graph layout, which stays at NAN (empty graph). When I now try going to my graphs overview, it doesn't show any graph at all.
When I click on detail, however, it displays the nan again...

OS: Centos 5.1
Cacti: cacti-0.8.7b
Rrdtool: 1.2.27


I have full debug logging activated, and all runs ok (my .rrd files get created correctly)

Anyone knows what I can check?
Thanks a Lot

What's "Settings->RRDTool Utility Version"?

Anything ugly in /var/log/httpd/error_log?
Reinhard

[Alex paris]

yes, there is one erreur, it shows like this "/bin/sh: /usr/share/cacti/site/poller.php: Aucun fichier ou répertoire de ce type(it means 'no file or repertory of this type')", i've tried to copy the file 'poller.php' under the /usr/share/cacti/site/, and i've given the permission to this file, but it still doesn't work

[gandalf]

Please post content of /etc/crontab (or wherever your distro defines cacti polling)

you're executing a php file with /bin/sh. I believe at first glance that you should be using the php binary.
For example /usr/bin/php /usr/share/cacti/site/poller.php
If it still doesn't work with the php binary, try posting php -i | grep configure to here. Generally you want atleast with-mysql and with-snmp in the configure statement for your php binary.

Hi there !

I've got the same problem with Cacti...

And, in my httpd/error_log, there is : ERROR: invalid text property format
ERROR: invalid text property format


Can you help me ?

regards !

I am having the same error. The graphs were working fine but then one morning they stopped when no one was even on the system. I looked at "/var/log/messages/" and the problem started shortly after: "pxeserver syslogd 1.5.0#1ubuntu1: restart." was logged, where pxeserver is our host. Any ideas?

[Hazeldark]

I have found why...

For me, I hadn't the good version of RRDTool...

You need the 1.2.23 version at least...

regards !

According to System Utilities->Technical Support I have:

Cacti Version 0.8.7b
Cacti OS unix
SNMP Version net-snmp
RRDTool Version RRDTool 1.2.x

So I doubt I am having the same error as Hazeldark.

Could be that your database was damaged on the reboot. There is a script in the cli directory called "repair_database.php", you should run it. Also, you Cacti Log would be very informative.

Thanks for your response, the graphs are now graphing properly.
