These columns identify the traffic between the host and the node channel and TCP/IP network connections in three levels of granularity:
- Blocks
- Messages
- KB
Blocks are made up of some amount of variable sized messages. ReadKB and WriteKB identify the KB involved in the traffic.
For host controller columns that provide overhead and management information, see ResUsageShst Table for details.
