SNMP - Interface Graphing

[dinux]

Well, lets start with the fact that I am new to both SNMP and Cacti. I have it up and running and graphing two systems using the Unix graphs for Load Averages and a few others. Any time I try something with SNMP and then run in the query verbose I get the following:

+ Running data query [1].
+ Found type = '3' [snmp query].
+ Found data query XML file at '/var/www/html/cacti/resource/snmp_queries/interface.xml'
+ XML file parsed ok.
+ Executing SNMP walk for list of indexes @ '.1.3.6.1.2.1.2.2.1.1'
+ No SNMP data returned
+ Found data query XML file at '/var/www/html/cacti/resource/snmp_queries/interface.xml'
+ Found data query XML file at '/var/www/html/cacti/resource/snmp_queries/interface.xml'
+ Found data query XML file at '/var/www/html/cacti/resource/snmp_queries/interface.xml'

Can someone help me out with why I am not getting an SNMP Data return please? Thanks !

Don't take this the wrong way, but is SNMP installed? If so, check if it is working by trying snmpwalk on a host. If you arent sure on how to use it, just man snmpwalk. Basically, the syntax (on an snmp1 host) would be:

snmpwalk -v <version> -c <community> hostname or ip

Like: snmpwalk -v 1 -c Public 192.168.1.5

That helps rule in or out SNMP as the issue. It would also help if you post your platform, and version, as well as the versions of Apache, net-snmp, php, mysql, etc... to make sure you are using compatible versions.

Haha! No worries. If you need something answered to help me, stupid or not, then I will give you what I can. First, the platform:

OS: Fedora Core 4
MySQL: Ver 14.7 Distrib 4.1.15, for redhat-linux-gnu (i386) using readline 4.3
PHP: PHP 5.0.4 (cli) (built: Nov 8 2005 08:27:12)
Apache: 2.0.54
net-snmp: 5.2.1.2

So to me it appears to be working fine. But like I said, I am new to SNMP and what not. Thank you for the help!

I agree, it looks to be installed correctly. Have you looked at the cacti logs and the SNMP cache? Try setting the logging to debug, then run poller.php from the shell. Does it run that way? If so, it may be related to permissions with the cacti user. When I was debugging my installation, I gave the cacti user a login shell, and su'd to _cacti then ran poller.php. I also know that PHP 5 isnt really supported. You may try removing PHP 5 and going back to PHP 4 (but the fact that you are graphing local stuff leads me to believe that PHP is fine). You are also able to walk the SNMP trees, so that looks to be ok too... I'd start with the cacti logs and the SNMP cache. Clear them both before you start, so that the errors will be easy to find.

Ok, so I had our Vice President of Software Engineering help me out and we got it working. He gave me a copy of our snmpd.conf files here and I tweaked it a little to match my settings and now we're up and running. Thank you much!

[ua_mk_2005]

Nice... I forgot about that. I guess I assumed that since you were able to run snmpwalk, that you had snmpd running. That's what I get for assuming. In the future, there is a really easy way to configure SNMP. Run snmpconf and it will ask you a series of questions that will allow you to create an snmpd.conf file. Once the file is created, you copy it to /usr/local/share/snmp (at least on *bsd) and then start snmpd on startup , linux may be different, with the System V init, and init levels and what have you... Glad you were able to get it working.
