Marek Walczak's entrepreneurial journey began in 1992 when he joined Bank Śląski as a COBOL programmer, later becoming an RPG developer on the IBM AS/400 system. His role evolved as he led a team for the unique ICBS system implementation, which involved extensive collaboration with IBM in Rochester, Minnesota.

It’s no secret that there is a skills gap in the IBM i world as the programmers and engineers who specialize in this operating system retire. It's definitely a problem, but forward-thinking companies are finding ways to overcome it and extend the value of their IBM i investments for years to come.

In today's fast-paced digital world, IT teams are under constant pressure to keep their IBM i systems running smoothly and prevent disruptions before they impact business operations. Two concepts- observability and monitoring-are often mentioned together, but they are not the same thing.

iBM i can run for years "without issues"... until one day everything looks like an issue at once. This post explains why threshold-based monitoring often misses the real causes of IBM i incidents - and how a behavioural approach (baseline + context) reduces alert noise and speeds up root-cause diagnosis.
