At last Friday’s OCEAN conference in Costa Mesa, Calif., IBM’s Dawn May and I presented “The Art of Performance Diagnostics,” showing how we’ve used tools that are free (Performance Data Investigator) and low-cost (Job Watcher) and included with IBM i to identify and resolve performance bottlenecks that would have been difficult using traditional green-screen tools alone.
One audience member said, “Developers should know about these tools! They aren’t just for system administrators.” With these tools and with documentation such as the IBM i Performance FAQ, performance expertise is within reach of developers as well as sysadmins.
How do IBM i performance tools help developers to be more effective? Developers can:
- Respond to any reported slowdowns by looking at recent performance data. IBM i captures performance statistics transparently, enabling developers or admins to “go back in time” to look at past performance.
- Even better, identify and resolve problems proactively during testing, rather than waiting for users to report problems.
