inquiry about FC uplink port statistics and snmpget

[russ.givens]

I'm trying to collect some QoS from our fabric interconnects and bring them into our enterprise monitoring solution.  One of the things I would like to collect information on is the Bytest Tx & Rx for the fiber channel uplink ports.  I think these are the two OID's from the Cisco-Unified-Computing-FC-MIB that I'm looking for but am unsure.

.1.3.6.1.4.1.9.9.719.1.20.5.1.6 - Bytes Rx Delta Avg

.1.3.6.1.4.1.9.9.719.1.20.5.1.11 - Bytes Tx Delta Avg

These two OID's correspond to the Avg column under statistics for the uplink FC ports.  The question I have is I'm uncertain if this is the information I'm looking for.  I'm looking for the average Rx and Tx Bytes.  The OID indicates it's a Delta Avg and I don't think I want that.  I want what the ports are transmitting and receiving not some delta between the present and last values.

Does anybody specifically now what these two OID's are for and if I have the wrong ones what would be the correct ones for what I'm trying to do.

Thanks.

Hi Russ,

If you want the value, from the Avg column, for Tx or Rx bytes, then the OIDs you have listed are correct.

If however, you want the amount of bytes and packets, for Tx and Rx, then the following OIDs should be used:

.1.3.6.1.4.1.9.9.719.1.20.5.1.4  = cucsFcStatsBytesRx
.1.3.6.1.4.1.9.9.719.1.20.5.1.9  = cucsFcStatsBytesTx

.1.3.6.1.4.1.9.9.719.1.20.5.1.15 = cucsFcStatsPacketsRx
.1.3.6.1.4.1.9.9.719.1.20.5.1.20 = cucsFcStatsPacketsTx

Further to this, if you want to match against some of the other statistics, best way to identify what OID is necessary is to do the following. When you have the FC Port selected in the left pane (of UCSM), ensure that you have the statistics in the right hand pane. Then right-click on the FC Port #, and select "Copy XML". Also, take a screenshot of the current statistics before they are updated (to ensure you can compare the XML to screenshot). You can then paste the XML output into a text editor and search for the corresponding values seen in your screenshot. When you find the appropriate value, you will find the variable name to be the same as the OID name. So you can compare the name with the entires in Cisco-Unified-Computing-FC-MIB to identify the corresponding numerical OID.

Hope that helps
