Graph data is empty

I have installed cacti following the instructions. The graph data is just
empty. The instructions say to add this to crontab: 
*/5 * * * * cactiuser php /var/www/html/cacti/poller.php > /dev/null 2>&1
Since I do not have an /etc/crontab I decided to put that in root's crontab
but saying:
*/5 * * * * su cacti -c php /home/www/cacti/poller.php > /dev/null 2>&1
That worked, but for some reason it could not write the RRDTool graphs
although I followed the instructions in setting permissions. At this stage
only the graph names were showing up under view graphs, not the actual
images. I then decided to run everything as root, finally the graph images
showed up but the data is empty. I have SNMP (net-snmp 5.2) running and I
have two rocommunity strings (mrtg and public) and I set it to use mrtg.
From what I can see it is communicating with the SNMPd properly but the
graph data is still empty. I have no idea what is wrong. My snmpd.conf is
very basic and consists of the following:
rocommunity  mrtg
rocommunity  public
load  1 1 1
disk / 100

PHP is not compiled with --enable-net-snmp, it is using the system snmpd. I
have mrtg traffic graphs running properly and I believe the snmpd is 100%
working. What could be the problem?

auto refreshing devices?

I'm not clear on how to auto refresh a device's interface list.  Certain 
devices, like channelized DS3 routers, get new users/interfaces turned up on 
a regular basis.

With cricket I wrote a script to rebuild the targets file (and also exclude 
any not "up" interfaces).  Is something similiar possible with cacti?

CatOS/6500 devices

Google shows this has been asked but I haven't found a good solution for 
pulling CatOS switches, and in particular 6509s/2948s, into cacti -with- 
ifDescrs (port names).

And ideally, this would only note ports that make sense and are up and 
ignore the VLAN-* interfaces as well as sc0.

Add the string

|query_ifAlias|

to the "Graph Title" (in "Graph Management") and
you're done.

I wasn't sucessful on customizing the templates, yet.

Best regards,

Re: CatOS/6500 devices

The OID I need is:

.1.3.6.1.4.1.9.5.1.4.1.1.4.$slot.$port

Port 9/44 is .1.3.6.1.4.1.9.5.1.4.1.1.4.9.44.

ifDescr on CatOS show what the port is ("10/100 utp ethernet (cat 3/5)") and 
ifAlias shows the same.

Anyways, how do I get this OID into the port display?

weather station

Can someone help me?
I'm searching a weather station to connect to cacti.
I found in the web some solutions but only by serial port. I think that I 
can read from a serial port but I have no script for this.
Can someone advice me about where I can find:
1) a script for serial port reading

or

2) A weather station with snmp support.

Thank You

How to configure cacti?

Re: How to configure cacti?

I would suggest you start with the "Documentation" of the Cacti website.
