No logs, no rrds no graphs, help?

[rspurlock]

All,

Hair is now all gone. I've searched the forums for help with this, uninstalled and reinstalled twice and I must be missing something simple. I have 0.8.6g installed, all the latest apps required also. No matter what I do, nothing is written to the log file. No rrd's are created, no errors show up anywhere. Yet no graphs are created. When I run the poller.php manually with the cactiuser user, all I get is this:

[cactiuser@ns1 log]$ /usr/bin/php /var/www/html/cacti/poller.php
Content-type: text/html
X-Powered-By: PHP/4.4.0

<br><strong>This script is only meant to run at the command line.</strong>

Nothing written to log. Nothing in apache log files.

If I take the rrd code and run it manually at cli using the cactiuser, it does create a rrd file in the rra folder. But nothing gets updated on the graph. It just says nan (not a number I assume).

Here is my crontab entry:

*/5 * * * * cactiuser /usr/bin/php /var/www/html/cacti/poller.php > /dev/null 2>&1


Everything else seems to work fine. I have the rrdtool set for version 1.2 in settings. It seems to talk snmp fine through website and the connection to mysql works fine.

Anyone have any idea where I could start? I just feel like I'm missing something simple here.

TIA,

Rob

I'm in the exact same boat, I thought it was permissions


no rra files are being created

I'm using the poller.php also, cron script same

I can see the under the poller cache that it's getting snmp stuff (cisco 6506) but it never saves them to rra databases.

is it because I'm using

rrdtool-1.0.46-32.1?

[rony]

Use rrdtool 1.0.49 or 1.2.x.

[rspurlock]

I'm using 1.2.11 currently. Surely someone has run into this problem?

BTW I'm running CentOS 3.5, Apache 2.0.46, PHP 4.4.0 and MySQL 4.1.14.

Anyone?

[rony]

What version of php is running the poller?

Do a php -v and post the results.

[rspurlock]

4.4.0

Redirect your cron output to a file for 1 or 2 passes of the poller and then review/tail that file and see what's up.

Ok, I set the crontab to output to a text file and I get this:

"/bin/sh: line 1: cactiuser: command not found"

So apparently by setting it up like I have doesn't work for the root crontab. So I removed it from root's crontab and set it up for cactiuser's crontab and I get the following:

Content-type: text/html
X-Powered-By: PHP/4.4.0

<br><strong>This script is only meant to run at the command line.</strong>Content-type: text/html
X-Powered-By: PHP/4.4.0

<br><strong>This script is only meant to run at the command line.</strong>

Same thing. Any ideas/ It's almost like it's just not running the script at all, but it is.

Try running the poller as root.


For some reason I can't get my poller.php to work unless it runs as root, as a normal user it produces the following output:

PHP Warning: socket_set_block() expects parameter 1 to be resource, boolean given in /var/www/cacti/lib/ping.php on line 97

perhaps i'm missing some sort of security issue related to php and creating sockets?

Please download the updated lib/ping.php from SVN. Here is the link. This will correct your problem.

Does anyone have any ideas about my issue? I can run the poller all day long and it spits out nothing and logs nothing. Does someone want to have a look themselves? I'll gladly open it up for a developer or helpful person to take a look.

TIA

*/5 * * * * cactiuser /usr/bin/php /var/www/html/cacti/poller.php > /dev/null 2>&1



There seems to be a bit of confusion for some users regarding the above line of code for a crontab entry. This code is meant to be placed in file in the cron.d directory, not in a user/root crontab. If you are editing root or preferably cactiuser's crontab with 'crontab -e' what you really want to enter is:

*/5 * * * * /usr/bin/php /var/www/html/cacti/poller.php > /dev/null 2>&1

Give that a try and see if your poller is working properly.
