Monitoring wireless conection

[sizulku]

HI,

I have a simple question that I do not know the answer to. What I
was wondering is it possible to track the Signal Strength, Noise Strength, and SNR for each connection to the Avaya wireless access points by using cacti. If so would you please let me know how do this.

Best regards,

I've found some package which is suitable for monitoring wiresless access point (http://www.raccoon.kiev.ua/projects/snr/), but since I'm not a programmer I didn't know how to interegrated it with cacti. Any help would be great.

best regards,

I did some searching, and couldn't come up with the exact MIB you need for this device (a MIB is an explanation of all the monitorable SNMP items). It seems that stats for this device are scattered across multiple MIBs.

So you can do one of a few things. If the code that you linked to can return the data you want as output (like command line), then you can just integrate that with cacti as a external datasource, like you would any of the local scripts.

Or using Net-SNMP run

Code: Select all

snmpwalk -c <community> <hostname> .1.3.6.1.4.1.762

this could be different depending on your version of Net-SNMP, but the OID at the end would be the same.

Given that output you can look at the textual string on the right, and find the specific OIDs in which you're interested. Having that, its not too dificult to create your own collector, or add on the the cacti one.

I recently started monitoring a Orinoco point-to-point wireless connection. I simply had to do a snmpwalk and start digging. I eventually found the signal strength and noise MIBs under the .private.enterprises. branch of the tree. Take a look in there until you find what you're looking for. For the Orinoco the MIBs are:
.private.enterprises.762.2.5.2.1.7.1
.private.enterprises.762.2.5.2.1.8.1

I could not find a MIB for SNR. I figure it's a calculated value. However, I don't know how to calculate it, sooooo, if anybody knows how, please respond!

Hi,

Here is the MIB

sent pakets local = .1.3.6.1.4.1.762.2.5.2.1.28.
recieve pakets local = .1.3.6.1.4.1.762.2.5.2.1.29.
sent pakets remote = .1.3.6.1.4.1.762.2.5.2.1.30.
recieve pakets remote = .1.3.6.1.4.1.762.2.5.2.1.31.
snr local = .1.3.6.1.4.1.762.2.5.2.1.47.
signal local = .1.3.6.1.4.1.762.2.5.2.1.48
noise local = .1.3.6.1.4.1.762.2.5.2.1.49.
snr remote = .1.3.6.1.4.1.762.2.5.2.1.51.
signal remote = .1.3.6.1.4.1.762.2.5.2.1.52.
noise remote = .1.3.6.1.4.1.762.2.5.2.1.53.

please let me know what you can do with it.
