Hi,

I'm running cacti 0.8.2a under OpenBSD 3.3.

My paths are set to /var/www/htdocs as Web Server Document Root and /cacti as cacti Web Root.

I have access to the cacti administartion interface and the permissions to the cacti paths are correct.

Code:

root@gattaca:/var/www/htdocs/cacti# ls -l
total 1194

...snip...

drwxr-xr-x  2 www   www        512 Jul 14 07:36 log

...snip...

drwxr-xr-x  2 www   www        512 Aug 13 11:19 rra

...snip...



But:
the scripts doesn't work because they are started from "var/www/...." and not "/var/www...."
The cronjob output shows this:

Code:

Subject: Cron <www@gattaca> cd /var/www/htdocs/cacti; /usr/local/bin/php cmd.php
X-Cron-Env: <SHELL=/bin/sh>
X-Cron-Env: <HOME=/var/www>
X-Cron-Env: <LOGNAME=www>
X-Cron-Env: <USER=www>

The exported graphs are empty: http://gattaca.dyndns.info/stat/

how can I fix this problem ?

Thx !

Are you still having problems with this? I ask because it looks like there is some data on your graphs now.

Hi,

I edited the data_input_data_cache manually.
In the column "command", I put a "/" in front of the path

Example:
perl var/www/htdocs/cacti/scripts/linux_memory.pl MemFree:
-->
perl /var/www/htdocs/cacti/scripts/linux_memory.pl MemFree:

Why did this error appear and how can I avoid it in the future ?

Bye
Steve

What happens if you comment out line 289 of 'include/functions.php' and clear your poller cache?

Hi raX,

this is the output:

Code:


cat: /proc/meminfo: No such file or directory
cat: /proc/meminfo: No such file or directory
[i]^^^  these two lines appear because there is no /proc/meminfo in OPenBSD. Don't care about it in the moment...[/i]

[i]...but the following line starting with 'sh' wasn't there before I made the changes you asked for.[/i]
sh: syntax error: unexpected EOF

If I undo my changes in the data_input_data_cache table (deleting the / in front of the path names), the old error still occurs:

Code:

...snip...

Can't open perl script "var/www/htdocs/cacti/scripts/loadavg_multi.pl": No such file or directory

I am trying to see if commenting out line 289 of 'include/functions.php' fixes your problem without you having to manually modify the 'data_input_data_cache' table. Is this the case?

Hi raX,

this doesn't help

Without "/" in front of the paths (e. g. perl var/www/htdocs/cacti/scripts/linux_memory.pl MemFree:) and Line 286 commented out:

What else can I try ?

That's good to hear, even though we aren't left with much of an answer as what went wrong. Let me know if you experience any more problems.
