I’m trying to find
the utilization of FC ports using snmpwalk.
After finding the information I see is ports are using more than 8gb.
Whereas physical ports speed is 8Gb. Looks like I’m missing
Can someone help me what I’m missing?
Using following command to get data out.
snmpwalk -v 2c -c public hostname 188.8.131.52.4.1.15184.108.40.206.220.127.116.11.11
SNMPv2-SMI::enterprises.1518.104.22.168.22.214.171.124.11.2 = Counter32: 2292858969
SNMPv2-SMI::enterprises.15126.96.36.199.188.8.131.52.11.3 = Counter32:
SNMPv2-SMI::enterprises.15184.108.40.206.220.127.116.11.11.4 = Counter32:
SNMPv2-SMI::enterprises.1518.104.22.168.22.214.171.124.11.5 = Counter32:
SNMPv2-SMI::enterprises.15126.96.36.199.188.8.131.52.11.6 = Counter32:
SNMPv2-SMI::enterprises.15184.108.40.206.220.127.116.11.11.7 = Counter32:
If I do the math ( 2292858969*4 )/ 1073741824 = 8.5Gb
Multiply counter with
4( word) , then converted bytes to gigabytes.
If I look at port utilization in Brocade GUI (performance utilization GUI) , it is hardly 64.5kb-8G..
Not sure what I’m missing here. Can you please help me. Attaching the switch GUI windows also, for your references
Thank you for the help

--->>>.....I see is ports are using more than 8gb.
Fibre Channel use other Data Rate as Ethernet.
e.g. show here for details

the MIB manual tell me following: "Counts the number of Fibre Channel words that the port has transmitted."
This means for my understanding that 8.5GB have been transmitted since the last reset or counter overflow.
There is no indication if the port has done this is 1 second or 1 hour or 1 year.
I hope this helps.

You can use BNA from Brocade, Cacti, MRTG or Nagios to monitor port utilization. There are many other tools on the internet to do this task.
It depends primary on your demand which tool fits best.
All freeware solutions will take some time to get them up and running.
