Troubleshooting Intermittent Problems
When intermittent problems occur, most IT professionals turn to packet capture to diagnose the problem. The OptiView analyzers make it easy to troubleshoot intermittent problems with advanced triggering and filtering to capture the traffic before, after or around the event occurrence and ensures the event is captured the first time to avoid doing random traffic captures that may not contain anything of interest. To capture a specific event the analyzer must inspect the contents of each packet to see if it matches a pattern or error message string which is indicative of the event occurring. The string matching is performed in hardware in real–time with linerate gigabit capture to ensure all the relevant packets are captured — after all, you can't analyze packets that were never captured. Um total de oito conjuntos dos acionadores ou dos filtros podem ser definidos para acionar uma captura sem supervisão para análise posterior, permitindo a análise quando que você tiver tempo e não quando o evento ocorrer.
