No graphs being displayed

[meister]

As a linux newbie I need a little help. I installed cacti under FC2 with the help of the guide and everything went well. I tried installing under RH9 and can't get the graphs to display. Also, not sure if it's related but I get this error when clearing the cacti.log from the ui.

Warning: unlink(/www/htdocs/cacti/log/cacti.log): Permission denied in /www/htdocs/cacti/utilities.php on line 195

Warning: touch(): Utime failed: Permission denied in /www/htdocs/cacti/utilities.php on line 196

Where can I start troubleshooting this?

[rony]

You can't clear the cacti.log from the UI unless your webserver has permissions to do so. And it not really suggested, from a security standpoint.

What do you mean graphs aren't working? Can you explain a little more, so I can begin to help you?

[meister]

I know snmp is working. It retrives the sys_name from the switch I am trying to graph. It just doesn't draw the graph. see pic.

This is what I get when I turn on debug mode in graph mamagement.

ERROR: opening '/www/htdocs/cacti/rra/drysdale_traffic_in_33.rrd': No such file or directory

Goto one of the data sources associated with one of the graphs and post the "Create Debug Syntax".

Please try this version of lib\rrd.php and see if you get better results. Please make sure it does not break anything by running poller.php from the command line.

Can I run it as root, or should I be cactiuser when I run it, or doesn't it matter?

[meister]

Well when I run it from the command line this is what I get. Please remember you are dealing with a newbie.

[root@safe lib]# ./rrd.php
-bash: ./rrd.php: Permission denied
[root@safe lib]#

If it helps, my catci/rra dir is basically empty.

[root@safe rra]# ls -alF
total 8
drwxr-xr-x 2 cactiuser users 4096 Sep 8 19:56 ./
drwxr-xr-x 11 1000 users 4096 Sep 16 06:44 ../
-rw-r--r-- 1 cactiuser users 0 Sep 8 19:56 .placeholder
[root@safe rra]#


Also my /catci/log/cacti.log file is empty.


How can I poll from the command line to get some error messages - just trying to find out where to begin looking.

I get the following from php poller.php

I thought it would make the rrd files on the fly it doesnt seem to.
ideas?

[dan.ross]

It appears something is broke in a cacti script somewhere. when I turned debug mode on in data source I get:
usr/local/rrdtool-1.2.11/bin/rrdtool create \

so i tried entering this manually and got the duplicat traffic_in counter error. So tediously I tried typing it in manually from the command line I intentionnaly left out the extra traffic_in and traffic_out entries and worked! i had a rrd file now. what do I need to edit so it stops trying to create duplicate traffic out entries???

[meister]

I just logged in as cactiuser and entered this manually and it worked.

-bash-2.05b$ /www/php/bin/php /www/htdocs/cacti/poller.php > /dev/null 2>&1

So all I have to do is remember to do it every 5 min and I should be good to go!!! lol

It's a bit of encourgement anyhow. At least I have some .rrd files and a graph now. Now to find why it doesnt execute from crontab.

[dan.ross]

here is the piece of offending code when I comment out the for each I eliminated the duplicate traffic entries but then I dont get any traffic_in statements.
IDEAS?

if (sizeof($data_sources) > 0) {
foreach ($data_sources as $data_source) {
/* use the cacti ds name by default or the user defined one, if entered */
$data_source_name = get_data_source_item_name($data_source["id"]);

$create_ds .= "DS:$data_source_name:" . $data_source_types{$data_source["data_source_type_id"]} . ":" . $data_source["rrd_heartbeat"] . ":" . $data_source["rrd_minimum"] . ":" . (empty($data_source["rrd_maximum"]) ? "U" : $data_source["rrd_maximum"]) . RRD_NL;
}

I have mine working now. I downgraded to version e, then I had to reload crond to get it to run every 5 min.

Working fine now.
