Unable to create interface graphs

[branix]

I did a clean install of cacti, I started the database from scratch, added the server (as device), and I wasn't able to do anything else from there (new screenshot attached).
Same config as in first post:
Mandrake linux 10.1 / Php 4.3.8 / net-snmp 5.1.2 / cacti 0.8.6c + patches (except for config.php).

The device is now marked as snmp v2 in cacti, and enabled in snmpd.conf.

It's definately a net-snmp issue. If you are using snmpv2, then it's questionable if you are using net-snmp or php_snmp. Do me one more favor, edit the snmp.php and look for a string that goes something like the following. You will find it in two places:

if (... == "WEBUI") {
$version = 1;
}

Delete those three lines and try again.

Same thing happens. I don't have php compiled with snmp support.

I will try today to change the net-snmp version that I am currently using and see more on that.

The problem may be caused by the following patch:

http://www.cacti.net/downloads/patches/ ... mibs.patch

Please back off and recheck.

Um, I didn't have a problem quering interfaces with the data query after I created that patch.

Let me know if backing off this patch resolves the issue.

[branix]

I'm sorry, I get almost the same output after downgrading.

[rony]

Doh!

Honestly, I'm glad that wasn't it.... But this is annoying...

Upgraded from 5.1.2 to 5.2.1

Code: Select all

[root@zus2 snmp]# snmpget -V
NET-SNMP version: 5.2.1

Same problem here ...

Branix,

We are thinking it may be a php issue with regular expression matching or something like a chomp type command (I don't have the source in front of me). However, when you look at your original post it looked something like:

...ifIndex='ifIndex.1 1'

When it should have read:

...ifIndex='1'.

The way that cacti receives output from php_snmp or net_snmp is as follows:

ifIndex.1 1

It then parses the data to return just "1". This parsing is broken.

Please be patient with me. Rony's working as well on this as there appear to multiple problems with FC.

Please run the following and post:

snmpwalk -OfntUe -v 1 -c public localhost

You should get something like:

Code: Select all

Downloading Mandrake 10.1 and FC3......

Going to install and try them. I want to find out why updating FC3 causes Cacti to break, and why you are having this problem in Mandrake 10.1.

[rony]

Very curious, please post the output of

Code: Select all

snmpwalk -OfntUe -v 1 -c public localhost

The device that you are quering, what is it? And what snmp agent is it running?

[branix]

I don't want to rush you guys into anything, as I said above I'm here now to help you with any piece of code/shell you might want.

The device is a pc running net-snmp as snmpd. As for Makndrake linux, I have installed it from the Offcial DVD (that's the 3CDs version), and after tah applied every official update.

I would like to help you guys (I'd go into the code myself), but I will not find the time until next week. I don't want to rush you into anything, because this is not a life/death situation, its just an issue

The output from the comand that you asked me to run is in a private message to you.
Here are some lines:

This is what we thought we would see. There is definately a problem with net-snmp's argument handling. I would appreciate it if you would send your copy of snmp.php to Rony as I will be away from my computer for about a week and he knows what to do.
