IPs in SNMP OIDs

JediFr3d · Post by **JediFr3d** » Fri Jul 13, 2012 4:04 pm

Similar to topic #41158 I'm trying to graph session counts of a Brocade ADX load balancer using SNMP on Cacti 0.8.8a.

I created an SNMP .xml query based on this page - http://www.cacti.net/downloads/docs/htm ... y_xml.html - and looking at the interface.xml that comes with Cacti.

I've tried various combinations of methods and sources in the 'ifSessions' field get the actual integer value (the session count) for each line, but so far I've only been able to get the query to pull the IP.

Can anyone shed any light on what I need to change to get it to pull the integer values of each line? Hopefully it's something simple that I've overlooked

Thanks!

Sample of snmpwalk output:

.1.3.6.1.4.1.1991.1.1.4.23.1.1.15.xx.yy.zz.10 = INTEGER: 5356
.1.3.6.1.4.1.1991.1.1.4.23.1.1.15.xx.yy.zz.11 = INTEGER: 872
.1.3.6.1.4.1.1991.1.1.4.23.1.1.15.xx.yy.zz.12 = INTEGER: 4222
.1.3.6.1.4.1.1991.1.1.4.23.1.1.15.xx.yy.zz.13 = INTEGER: 4398
.1.3.6.1.4.1.1991.1.1.4.23.1.1.15.xx.yy.zz.14 = INTEGER: 498

My XML query:

Code: Select all

<query>
	<name>Get Brocade ADX VIPs</name>
	<description>Queries a Brocade ADX for a list of monitorable VIPs</description>
	<oid_index>.1.3.6.1.4.1.1991.1.1.4.23.1.1.15</oid_index>

Please use

Code: Select all

<source>value</source>

for the <fields> as you already have the correct index.
You may want to have a read at the "Alteon Loadbalancer Templates" that I published years ago. This may help understanding

Thanks for the reply

I tried changing that line, but it still doesn't appear to work:

Code: Select all

<query>

	<description>Queries a Brocade ADX for a list of monitorable VIPs</description>

	<index_order_type>numeric</index_order_type>
	<index_title_format>|chosen_order_field|</index_title_format>

			<oid>.1.3.6.1.4.1.1991.1.1.4.23.1.1.15</oid>
		</ifSessions>
	</fields>
</query>

I think I tried about 15 different modifications of the ifSessions field last night (changing methods, sources, adding a . to the oid, omitting the oid entirely, etc), all to to no avail.

Any other ideas?

Change input to output on ifSessions and do a verbose query. You should see numbers, then, as a proof for my assumption. Else, I have to dig deeper ...

If I change output to input (which is what I think you meant?) then I do get numbers:

Code: Select all

+ Located input field 'ifSessions' [walk]
+ Executing SNMP walk for data @ '.1.3.6.1.4.1.1991.1.1.4.23.1.1.15'
+ Found item [ifSessions='8114'] index: xx.yy.zz.10 [from value]

+ Found item [ifSessions='3842'] index: xx.yy.zz.15 [from value]
+ Found item [ifSessions='426'] index: xx.yy.zz.23 [from value]

However from reading the docs, I thought input was designed for things that don't change (or change very rarely), and output was for things like sessions, packet counts, etc?

http://www.cacti.net/downloads/docs/html/snmp_query_xml.html wrote:A rule of thumb is that input fields contain semi-static data that is not graphable, while the output fields contain the data that will be graphed.

Sure, you're right. This was for testing only! But now you SEE the data you expect to graph. Please change back to "output" again and perform same procedure for all <fields>

After changing that one word, the verbose output no longer contains any mention of my ifSessions field.

Without wanting to jump to conclusions, could this be a bug?

Quick update: I've tried the same SNMP queries on a fresh 0.8.7g installation (on the same system) as well as another older 0.8.8a system and they also didn't work on either.

I don't think your Data query debug will/should show the values it's going to poll, it's a debug to make sure your indexes work correctly (and it appears as though they are).

Changing the direction (input/output) was a test to make sure you were getting data from the SNMP query... you are... now you should be able to change the direction back and move onto the next step and create your data sources/graphs/etc....
