Abstract

Embodiments relate to an enhancement of a function measurement block. An aspect includes obtaining common statistics from a function table. An aspect includes obtaining adapter-specific statistics from an adapter. An aspect includes providing the common statistics and the adapter-specific statistics in the function measurement block. An aspect includes providing adapter-specific counters in the function measurement block.

First claim

What is claimed is:

1. A computer system for enhancing a function measurement block, the system comprising:
a memory having computer readable instructions; and
a processor configured to execute the computer readable instructions, the instructions comprising:
obtaining common statistics from a function table;
obtaining adapter-specific statistics from an adapter;
providing the common statistics and the adapter-specific statistics in the function measurement block; and
providing adapter-specific counters in the function measurement block,

wherein a function associated with the adapter is reflected in a format field of the function measurement block, and
wherein when the format field has a first value, a section of the function measurement block is associated with a direct memory access read counter and a direct memory access write counter.

2. The system of claim 1 , wherein when the format field has a first value, a section of the function measurement block is associated with a received bytes counter that is incremented based on a number of bytes received on an Ethernet interface during an update interval, a received packets counter that is incremented based on a number of packets received on the Ethernet interface during the update interval, a transmitted bytes counter that is incremented based on a number of bytes transmitted on the Ethernet interface during the update interval, and a transmitted packets counter that is incremented based on a number of packets transmitted on the Ethernet interface during the update interval.

3. The system of claim 1 , wherein when the format field has a first value, a section of the function measurement block is associated with a consumed work units counter that is incremented based on a number of work units processed by a peripheral component interconnect function associated with the adapter during an update interval and a maximum work units counter that represents a maximum number of work units that the peripheral component interconnect function is capable of processing over a given time period.
