PROFILE
Johannes Ziemke
Over a three-month period, Jan built and enhanced AIX monitoring capabilities in the prometheus/node_exporter repository, focusing on deepening system observability for enterprise environments. Using Go and Prometheus, Jan developed new collectors and metrics for CPU usage, disk I/O, memory paging, network statistics, and partition details, enabling more granular performance analysis and capacity planning. The work included refining diskstats reporting, introducing per-interface network counters, and adding CPU context switch statistics. Jan also addressed critical bugs affecting CPU usage calculations and disk block size conversions, demonstrating thorough attention to data accuracy and reliability in system monitoring and performance metrics collection.
