Diagnostic Tools
The selection of diagnostic tools available for your server range in complexity from a
comprehensive validation test suite (Oracle VTS) to a chronological event log (Oracle ILOM
System Log). The selection of diagnostic tools also includes standalone software packages,
firmware-based tests, and hardware-based LED indicators.
The following table summarizes the diagnostic tools that you can use when troubleshooting or
monitoring your server.
Diagnostic Tool Type What It Does Accessibility Remote Capability
