Poller.php won't poll. Permissions ?

[nomojo]

Hi All,

I'm new to Cacti and am having trouble getting off the ground. Got a problem with poller.php / cmd.php on a box with the Plesk control panel installed. My gut says it's permissions, but I can't figure this out.

Trying to create the load average graph in the "Local Linux Machine". Created a device with IP 127.0.0.1, created the graph, and put it the default tree, however the graphs display as broken images. After several cron runs there is nothing in /rra

I've got a user cactiuser that belongs to groups cacti, apache, and psaserv (Plesk group) - I'm taking shots in the dark here.

[cactiuser@vs1 cacti]$ php poller.php

But cactiuser can run perl scripts from cln:

[cactiuser@vs1 scripts]$ /usr/bin/perl ping.pl 127.0.0.1
0.118[cactiuser@vs1 scripts]$

Here's the loadaverage script I'm trying to create a graph for:
[cactiuser@vs1 scripts]$ /usr/bin/perl loadavg.pl
0.68 1.19, 1.50[cactiuser@vs1 scripts]$

Just for grins, here's one without the complete path to perl:
[cactiuser@vs1 scripts]$ perl ping.pl 127.0.0.1
0.089[cactiuser@vs1 scripts]$

Here's what binaries my system is using:
[cactiuser@vs1 scripts]$ which php
/usr/bin/php
[cactiuser@vs1 scripts]$ which perl
/usr/bin/perl
[cactiuser@vs1 scripts]$ which rrdtool
/usr/local/bin/rrdtool


I've read everything I can find on the board with no luck.

My configuration info follows.

Thanks in advance.

Do the settings on your console -> settings -> Path tab

match these:

[cactiuser@vs1 scripts]$ which php
/usr/bin/php

[cactiuser@vs1 scripts]$ which rrdtool
/usr/local/bin/rrdtool

Yes, the paths match:
