PROFILE
Johannes Ziemke
Worked on expanding AIX monitoring capabilities in the prometheus/node_exporter repository, delivering six features and resolving two bugs over three months. Developed new collectors and enhanced existing ones to expose detailed metrics for CPU usage, disk I/O, memory paging, network statistics, and partition information on AIX systems. Leveraged Go and Prometheus client libraries to define new descriptors, update collectors, and ensure backward compatibility with existing dashboards. Addressed critical data accuracy issues by refining CPU usage calculations and disk block size conversions. These contributions improved observability, troubleshooting, and capacity planning for enterprise AIX environments, supporting more reliable and data-driven system operations.
