Monitoring MSM system metrics with SNMP/MRTG

pt307 — Tue, 28 Feb 2012 10:55:19 GMT

Hi,

I'm trying to chart our MSM765zl's CPU and RAM utilisation over a period of time using MRTG. The MIB Reference Guide suggests using .1.3.6.1.4.1.8744.5.21.1.1.5 for current usage and .1.3.6.1.4.1.8744.5.21.1.1.10 for available system RAM, however they don't seem to exist on the controller:

$ snmpget -v2c -c public 192.168.100.248 .1.3.6.1.4.1.8744.5.21.1.1.5
iso.3.6.1.4.1.8744.5.21.1.1.5 = No Such Instance currently exists at this OID

$ snmpget -v2c -c public 192.168.100.248 .1.3.6.1.4.1.8744.5.21.1.1.10
iso.3.6.1.4.1.8744.5.21.1.1.10 = No Such Instance currently exists at this OID

In fact there doesn't seem to be much at all in the 8744 tree:

$ snmpwalk -v2c -c public 192.168.100.248 | grep 8744

iso.3.6.1.2.1.1.2.0 = OID: iso.3.6.1.4.1.8744.1.47
$

Am I missing something obvious? Is anyone else successfully charting system metrics in MRTG/Cacti/etc?

I use PRTG for monitoring at many customers. I have had the same questions about PRTG and MSMs. Perhaps we can collaborate on this and figure it out?

We use this OID

1.3.6.1.4.1.8744.5.21.1.1.5.0

from:

COLUBRIS-USAGE-INFORMATION-MIB :: coUsInfoCpuUseNow
Name coUsInfoCpuUseNow
MIB COLUBRIS-USAGE-INFORMATION-MIB
Oid 1.3.6.1.4.1.8744.5.21.1.1.5.0

Path iso . org . dod . internet . private . enterprises . colubris . colubrisMgmtV2 . colubrisUsageInformationMIB . colubrisUsageInformationMIBObjects . coUsageInformationGroup . coUsInfoCpuUseNow . 0
Base-Type Integer
Value-Ranges 0 to 4294967295
Description
"Current CPU usage."

This is also a good one, gets the current amount of connected wireless clients.

1.3.6.1.4.1.8744.5.25.1.7.2.0

coDeviceWirelessClientStatusGroup
MIB COLUBRIS-DEVICE-WIRELESS-MIB
Oid 1.3.6.1.4.1.8744.5.25.1.7.2.0
Path iso . org . dod . internet . private . enterprises . colubris . colubrisMgmtV2 . colubrisDeviceWirelessMIB . colubrisDeviceWirelessMIBObjects . coDeviceWirelessClientStatusGroup . 2 . 0
Index / Unknown 2.0

See the attached pic for an example of both, CPU is the top one.

cheers,

Matt.

Thanks Matt. Looks like MRTG needed the .0 at the end of the OID... oops :)

Clients connected will definitely be a handy one too.

Also, has anyone been able to monitor the traffic of each Radio1 and Radio2 for a given AP? I've tried adding the AP and associated radios, but the name displayed VERY generic, it only shows an index # like 33853 or 34772, etc. It doesn't tell me the actuall AP device name (for example, the serial number) and Radio itself. Do you know what I mean? (I have found that, if I turn sFlow on the MSM controller, the AP device names DO show properly but... I'd rather not enable sFlow if I don't have to).

I can provide screenshots to explain this better...

Can anyone point me to the right MIB file to monitor the # of client connections on a given AP/radio? Having trouble finding whih MIB to use?

Just an FYI. the MIB file you need to get the # of associated clients on a Controlled AP's Radio is "COLUBRIS-DEVICE-WIRLESS-MIB.my". It seems to be working well for me right now.

Once I imported it into my PRTG monitoring software using their MIB importer, it ended up looking like this:

<?xml version="1.0" encoding="ISO8859-1" ?>

</version>

</system>

<list>

<entry>

Hi,

Thanks for the info, they work great.

I don't suppose you have an OID for the number of connected AP's into a team?

Thanks,

Glen.

Sorry, I never needed that info via SNMP so don't have an answer for you.

Need help with MSM deployments?
