Compression measurement for computer servers

Abstract:

According to one or more embodiments of the present invention, computer implemented method includes obtaining by an input/output (I/O) subsystem a request block that includes a command code indicating a STORE IOP-UTILIZATION DATA command for tracking resource utilization during an asynchronous execution of an instance of a CPU DEFLATE command. The method further includes, based on the command code, initiating a command response block. The command response block includes multiple entries for input/output processor (IOP) utilization, each entry corresponding to resource utilization measurements of each IOP in the I/O subsystem. The method further includes, storing, in a command response code field of the command response block, a response code indicating that the resource utilization measurements have been recorded in the entries for IOP utilization. The response block includes a length code indicating a length of the response block and the response code field.
