Troubleshooting the NetProfiler

Troubleshooting SteelCentral can be a complex process involving looking at multiple different areas of the product.

In its simplest form, the NetProfiler is divided into two distinct areas: the Web-based UI and the supporting infrastructure (system processes, scripts, and so on). Problems can occur in one area only or across multiple areas. For example, identifying why specific data is missing from a report might reveal a problem with the way the report is being run (a UI-based problem), a problem with the underlying query processing engine (an infrastructure-related problem), or a combination of the two.

This chapter includes troubleshooting information in the following areas:
