ERROR: opening '/www/htdocs/cacti/rra/...:No such file ...

[arcturus]

Hi,

I'am triyng to start with cacti (first time ). I've followed all the instructions in the pdf - Installation HOW-TO For lINUX, BY llee Carter.
I've FC3 and cacti-0.86e. By default cacti's generates grafs for the localhost, but i can't see them. When i turn on the debug mode for the graph i get this message:
RRDTool Says:

ERROR: opening '/www/htdocs/cacti/rra/localhost_load_1min_5.rrd': No such file or directory.
The permissions in /www/htdocs/cacti/ rra/ and log/ are:
#drwxr-xr-x 2 cactiuser users 4096 Jun 21 01:46 log
#drwxr-xr-x 2 cactiuser users 4096 Jun 21 01:46 rra

This files are not generated. Why?

Thanks in advance,

Hi,
Are you sure the crontab line is correct? Do you try to run cmd.php as cactiuser?

[arcturus]

Hi Pierre,

thanks for the reply.
The line on the file crontab is "*5**** cactiuser /www/php/bin/php /www/htdocs/cacti/poller.php > /dev/null 2>&1"


My crontab is like this:

SHELL=/bin/bash
PATH=/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=root
HOME=/

# run-parts
*5**** cactiuser /www/php/bin/php /www/htdocs/cacti/poller.php > /dev/null 2>&1
01 * * * * root run-parts /etc/cron.hourly
02 4 * * * root run-parts /etc/cron.daily
22 4 * * 0 root run-parts /etc/cron.weekly
42 4 1 * * root run-parts /etc/cron.monthly

I've run the cmd.php as cactiuser and i've got this:

[cactiuser@cmviseu root]$ /www/php/bin/php /www/htdocs/cacti/cmd.php
#!/usr/bin/php -q

Once again, i'am new working with cacti and Linux.
Thanks in advance for any help.

You are writing your rrd files in a sub directory of webroot. Check your selinux settings. This is a common gotcha with fedora.

Also,
what does a tail of your cacti log & /var/log/httpd/error_log say?

[elnino]

Arcturus, try changing your crontab to:
*/5 * * * * cactiuser /www/php/bin/php /www/htdocs/cacti/poller.php > /dev/null 2>&1

I think missing the slash in there for the minute part and not having the spaces between the other time intervals might make it not run at all.

Hi,

My problem is that the rrd files are created in a directory but Cacti tries to read it in another directory.
the rrd files are created in the directory /var/www/html/cacti/rra/ but it says that it can't create graph as no such file has been found. It looks at the directory /usr/share/cacti/rra/ instead of where it has been created.
If anyone can help me to solve this problem.
Thank you
