This document is a technical report detailing the benchmark tests conducted on the VitalSigns SIEM Agent for z/OS version 4.3. The tests were performed on an IBM z16 system to evaluate the performance of the agent in processing SMF events and console messages. The report outlines two main test scenarios: one focused on processing a mixed workload of SMF records and the other on handling console messages generated by a REXX exec. The results indicate that the agent achieved a high zIIP eligibility rate, ranging from 99.77% to 99.97%, and a consistent zIIP offload percentage between 92% and 93%. The performance metrics include the number of records processed, CPU time utilized, and the efficiency of event message formatting and transmission to a TCP server. Additionally, the report includes detailed tables of CPU time usage and event counts for various tasks during the tests, providing a comprehensive view of the agent's performance under different workloads.
