Monitoring MSM system metrics with SNMP/MRTG
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?
Paul

Re: Monitoring MSM system metrics with SNMP/MRTG
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?

Re: Monitoring MSM system metrics with SNMP/MRTG
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.

Re: Monitoring MSM system metrics with SNMP/MRTG
Thanks Matt. Looks like MRTG needed the .0 at the end of the OID... oops :)
Clients connected will definitely be a handy one too.

Re: Monitoring MSM system metrics with SNMP/MRTG
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...

Re: Monitoring MSM system metrics with SNMP/MRTG
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?

Re: Monitoring MSM system metrics with SNMP/MRTG
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" ?>

<system>
<version>

Re: Monitoring MSM system metrics with SNMP/MRTG
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.

Re: Monitoring MSM system metrics with SNMP/MRTG
Sorry, I never needed that info via SNMP so don't have an answer for you.
