In our previous article on GatewayScript concurrency, we explored how to understand and optimize GatewayScript engine performance. But how do you monitor these engines in real-time without constantly logging into the DataPower CLI?

The answer: DataPower’s REST Management Interface. This powerful API allows you to programmatically query GatewayScript status and build automated monitoring solutions.

When troubleshooting API issues in IBM API Connect, understanding what happened between your gateway and backend services is crucial. API Connect provides detailed backend logging capabilities through its API Event Record fields.

“Which portal should I use?” This is one of the most common questions I hear from teams implementing IBM API Connect. The answer isn’t always obvious—IBM offers four distinct portal options, each designed for different use cases. Choose wrong, and you’ll either over-engineer a simple solution or find yourself constrained by limitations you didn’t anticipate.

Let me walk you through the four options, when to use each one, and how to make the right choice for your API program.

Your API Gateway is slow under load. GatewayScript engines are maxed out. Requests are queuing. Sound familiar?

Understanding the relationship between GatewayScript engines, CPU cores, and concurrent execution is crucial for building high-performance API solutions. This guide cuts through the complexity with battle-tested formulas and real-world recommendations for handling high-concurrency scenarios.
