Poller appearing to hang on RH7.2

[bafjohnson]

Hi all,

am using Cacti 0.8.6h on RH7.2. Cacti was compiled from the source .tar.gz.

I have been adding devices, data sources etc. and have had no luck with graphs being updated. The graph is created - but seems to have no data on it.

If run poller.php from the command line with just localhost defined all seems fine, graphs are updated etc.

However if I add a device and a data source then poller appears to hang. Running it from the command line gives the following:


[root@netsaint scripts]# php /usr/local/cacti/poller.php
OK u:0.00 s:0.01 r:0.00
OK u:0.00 s:0.01 r:0.00
OK u:0.00 s:0.01 r:0.00
OK u:0.00 s:0.01 r:0.00
OK u:0.00 s:0.01 r:0.00

<b>Warning</b>: 20 is not a valid File-Handle resource in <b>/usr/local/cacti/lib/rrd.php</b> on line <b>47</b><br>

The command which the data source derives data from is a script which is called with:

perl /usr/local/cacti/scripts/get-w2k-cpu <management_ip>

The poller cache shows:

Data Source: kaleidos-01.content.ifl.net - win2k-cpu
RRD: /usr/local/cacti/rra/kaleidos01_content_ifl_net_win2k_cpu_42.rrd
Action: 1, Script: perl /usr/local/cacti/scripts/get-w2k-cpu kaleidos-01.content.ifl.net

If I run perl /usr/local/cacti/scripts/get-w2k-cpu kaleidos-01.content.ifl.net it returns a value.

Can anyone make any suggestions?

Thanks in advance,

Ben

Hi

what version of PHP are you running ?

The Cacti installation guide (http://www.cacti.net/downloads/docs/htm ... ments.html) says this :

Cacti requires that the following software is installed on your system.
* RRDTool 1.0.49 or 1.2.x or greater
* MySQL 3.23 or greater, 4.0.20d or greater highly recommended for advanced features
* PHP 4.1 or greater, 4.3.6 or greater highly recommended for advanced feature

Hi there,

thanks for the quick response.

what version of PHP are you running ?

[root@netsaint rra]# php -v
4.1.2

So it's within the bounds of what should work.

I've just created a new cacti install in a new directory, with a new DB and a new user. I thought I fresh start may be good. I am still seeing the same problem. Except this time my rrd's aren't being created at all!

Thanks,

Ben

what version of PHP are you running ?

I upgraded to php 4.4.2 (built from source this morning)

[root@netsaint conf]# php -v
PHP 4.4.2 (cli) (built: Mar 30 2006 09:18:51)
Copyright (c) 1997-2006 The PHP Group
Zend Engine v1.3.0, Copyright (c) 1998-2004 Zend Technologies


and the whole lot started to work.

Thanks for the help!

Cheers,

Ben
