[gpfsug-discuss] RDMA data from Zimon

Hi,

	Can one of the IBMers tell me if port_xmit_data and port_rcv_data from Zimon can be interpreted as RDMA Bytes/sec? Ideally, also how this data is being collected? I’m looking here: https://www.ibm.com/support/knowledgecenter/en/STXKQY_5.0.0/com.ibm.spectrum.scale.v5r00.doc/bl1hlp_monnetworksmetrics.htm <https://www.ibm.com/support/knowledgecenter/en/STXKQY_5.0.0/com.ibm.spectrum.scale.v5r00.doc/bl1hlp_monnetworksmetrics.htm>

	But then I also look here: https://community.mellanox.com/docs/DOC-2751 <https://community.mellanox.com/docs/DOC-2751>

	and see "Total number of data octets, divided by 4 (lanes), received on all VLs. This is 64 bit counter.” So I wasn’t sure if some multiplication by 4 was in order.

	Please advise.

Cheers,
Kristy
