Has anyone successfully used CISCO-OPTICAL-MONITOR-MIB to graph historical optical light level data ...

BRIAN SEKLECKI · ‎03-14-2015

Per the Cisco manuals, this proprietary MIB is supported on ONS 9.x release: http://www.cisco.com/c/en/us/td/docs/optical/15000r9_0/dwdm/reference/guide/454d90_ref/454d90_snmp.html#wp48340 -- However, I've tried a combination of 9.1, 9.2, 9.4, 9.6.x systems, both Transponder, TCC, and mixed WSS M6/M12 shelves, and table CISCO-OPTICAL-MONITOR-MIB::cOpticalMonTable always has zero entries.

My goal is to graph historical optical light levels historically on a RRDTool based system such as Cacti or MRTG (Both on Trunk and Transponder Cards).

While not SNMP, you can try this if you havent found anything yet.

Open a web browser and go to:
http://x.x.x.x/pm/15m/0

Where x.x.x.x is the IP of your node.

(Login if you have to)

You should see the performance metrics pull in a close approximation to:

LINEWL-1-2-3-RX-1543.73,och,9208,448,448,448,T,T,T
LINEWL-1-2-3-RX-1558.98,och,9246,461,461,462,T,T,T
LINEWL-1-2-3-RX-1560.61,och,9250,443,443,444,T,T,T
LINEWL-1-2-3-TX-1531.12,och,9349,400,401,402,T,T,T
LINEWL-1-2-3-TX-1532.68,och,9353,402,402,403,T,T,T
LINEWL-1-2-3-TX-1533.47,och,9355,402,403,404,T,T,T

In CSV order:

Interface Name as Shelf-Slot-LINE-Lambda,type,Index,MIN,AVG,MAX

Now the MIN, AVG and MAX are calculated as follows: (n-500)/10

So in this case, TX for 1532.68 has a MIN value of: (402-500)/10 = -9.8dBm

Use cURL for retrieval and Python/Perl/Ruby for parsing and insertion into EMS (We used Zabbix) and you should be well on your way.

Adam,

I was working on this with a colleague, and he had to use:

http://x.x.x.x/pm/15min/0

instead.

But it works.

Also http://x.x.x.x/pm generates a bunch of data.

How did you discover this? Have you found other data that's accessible via http?

Thanks
