So I'm finaly there! I've done a fresh install of cacti 0.8.6i on Fedora Core 5 and decided to start from scratch. I've also decided to redo my work on templates for BigIP. Here is the first one I've got working.

This template will give you functionality to graph BigIP interface traffic (bits/sec in and out on physical interfaces). The statistics is gathered from statistics in the F5-BIGIP-SYSTEM-MIB.txt.

The SNMP data query also includes functionality for doing more than just Bytes in/out statistics. So if you want you can graph packets in/out, interface drops etc. The only thing you must do is create templates for this in the GUI and post it back here

.

Please give it a try and report back.

Revision history:
1.0 - Initial version
1.1 - Minor cosmetical updates to get better looking graphs (2006.11.07).

Best regards

The following simple template graphs the sysStatClientCurConns value from the F5-BIGIP-SYSTEM-MIB. This graph will show the current connections from client side, the value is global summary for the system.

The template is made with cacti 0.8.6i.

Revision history:
1.0 - Initial version (2006.11.07).

My problem with long OID's and Cacti is now solved. The problem is described in detail here http://forums.cacti.net/about16772.html.

In short terms the problem is that the OID index i have to use to poll BigIP vs statistics is a numeric representation of the vs name. When the vs names got too long i got NaN's in the graphs.

The solution was, in my case, upgrading to Cacti 0.8.6i.

I will post a new host template with my new setup for vs connection and traffic monitoring as soon as I'm finished testing it.

Best regards

I upgraded to 8.6i and installed the new templates. I'm able to graph a lot of things now, but for some reason I'm not getting any actual data in my graphs. Not sure if this is Cacti related or F5 related at this point...

Please follow the instructions of my "NaN Debugging" howto

I guess I should clarify.

Cacti has been up and running for several months. I recently upgraded my F5's from 2400s to 3400s (and from 4.5.14 to 9.1.2 on the software side).

On cacti 8.6h, my old graphs were pulling interface stats fine hitting the bigip as a default snmp host. My graphs got wierd after the bigip upgrade, so i downloaded tgravvolds fix, and upgraded cacti to the i version as well.

Everything is up and running smooth, and cacti seems to query and find the mibs on the BigIP. The graphs are drawn, and there aren't NaN errors, but I just don't get any data on the graph.

I'll work through your HowTo to see if I missed something.

okay, i have the following error in cacti.log:

11/16/2006 03:24:48 PM - CMDPHP: Poller[0] Host[109] DS[1203] WARNING: Result from SNMP not valid. Partial Result:
11/16/2006 03:24:48 PM - CMDPHP: Poller[0] Host[109] DS[1203] SNMP: v1: 10.2.1.20, dsname: collisions, oid: .1.3.6.1.4.1.3375.2.1.2.4.4.3.1.12.3.49.46.49, output: U

So, please snmpwalk this OID (.1.3.6.1.4.1.3375.2.1.2.4.4.3.1.12.3.49.46.49) and post the results (_no_ community strings in posts, please)

Nice to see that somebody actually uses the templates

.

Have you tried to poll the snmp OID with snmpwalk? Try to run snmpwalk -v 2c -c <snmp_community> <hostname> .1.3.6.1.4.1.3375.2.1.2.4.4.3.1.12.3.49.46.49. What result do you get? You should get something like:
SNMPv2-SMI::enterprises.3375.2.1.2.4.4.3.1.12.3.49.46.49 = Counter64: 0

The OID you refer to here is the OID for graphing collisions on a physical interface on the BigIP v9.x device, do you have the same problems with other OIDs, like for example bytesin/out?

Also remember when using the Interface Statistics data query that you have two types of graphs to choose from, Interface errors/drops/collisions and traffic (bits/sec). You have to select the type before creating the graph, use "select graph type" (look for it under the interface list).

Good luck!

I get nothing back from the BigIP when I do a walk of the OID. I tried various other OIDs that had errors in cacti.log, and get the same lack of response.

I belive you've already double-checked the snmp config on your BigIP? Pay attention to any restrictions under the snmp community. To get full snmp access you have to enter .1 in the OID field of the snmp community config.

Can you pull any other data via snmp from the BigIP? For Example can you run snmpwalk -v 2c -c <your_community> <hostname> system. Wich version of the BigIP OS do you run, my version is 9.2.3.

After installation of the new BigIP, I was getting SNMP data, but it wasn't matching the stats on the actual BigIp itself.

(Hence my cacti upgrade and installation of the above tools).

When I do "snmpwalk -c foo -v 1 system" I get a full dump from the box and can see all the MIBs. (I can pull via -v 2c as well).

version: BIG-IP 9.1.2 Build 69.0

AHA!

When I do a walk of the specific OIDs using -v 2c i get valid input.

By default we use v1 here.

Okay, so the end solution is that for the BigIP template you MUST use v2 SNMP, v1 doesn't work.
