Graphs don't work since system upgrade

[Christoph]

Hi there!

Unfortunately i decided yesterday to upgrade my Debian Sarge Linux box. Before the upgrade i used Cacti 0.8.6b and everything worked fine. Since the update the graphs don't show up anymore. Instead of the graph i see only a "picture" which can't be loaded inside the webbrowser.

To exclude compatibilty problems i upgraded Cacti to 0.8.6c, but this didn't help. Still no graphs. I set logging to debug and when i try to open one graph this line shows up:

Code: Select all

01/09/2005 11:10:22 PM - WEBLOG: Poller[0] CACTI2RRD: /usr/bin/rrdtool graph -  --imgformat=PNG  --start=-86400  --end=-300  --title="knecht - Logged in Users"  --rigid  --base=1000  --height=120  --width=500  --alt-autoscale-max  --lower-limit=0  --vertical-label="users"  DEF:a="/usr/share/cacti/rra/localhost_users_6.rrd":users:AVERAGE  AREA:a#4668E4:"Users"   GPRINT:a:LAST:"Current\:%8.0lf"   GPRINT:a:AVERAGE:"Average\:%8.0lf"   GPRINT:a:MAX:"Maximum\:%8.0lf"

Debug Mode says nothing but "RRDTool Says:". No error output. Paths and user rights should be ok. Just doublechecked them. The logging of the data works, all files inside the cacti/rra directory are updated every five minutes.

Unfortunately, i've got no clue what else i can do Any suggestions? Here are the versions i'm using:

RRDtool 1.0.49
Cacti 0.8.6c
PHP 4.3.10-2 (cli)
mysql Ver 12.22 Distrib 4.0.23, for pc-linux-gnu (i386)

Thanks

Downgraded to

PHP 4.3.9-1 (cli) (built: Oct 5 2004 08:45:32)

but it didn't help. Still no graphs.

Thanks

Thanks for your help TheWitness. I set all log features inside inside "Cacti Settings (General)", so that i get as much logs as possible. Here's the log of a a graph on the number of TCP Connections:

// Edit: Gosh i am stupid.... Somehow i screwed up my php.ini, safe_mode was set to "on". So php couldn't execute rrdtool...I set it to off and everything works fine again.

Sorry for bothering you and thanks for your help
