The output includes the following: • Load is defined as number of running processes. The average reflects the system load over the past 1, 5, and 15 minutes. • Processes displays the number of processes in the system, and how many are actually running when the command is issued. • CPU states shows the CPU usage percentage in user mode, kernel mode, and idle time in the last one second. • Memory usage provides the total memory, used memory, free memory, memory used for buffers, and memory used for cache in KB. Buffers and cache are also included in the used memory statistics. Example B-6 show system resources Command switch# show system resources Load average: Processes : CPU states : Memory usage: 2340K buffers, 1 minute: 0.00 5 minutes: 0.00 15 minutes: 0.00 152 total, 3 running 0.0% user, 0.0% kernel, 100.0% idle 960080K total, 412900K used, 547180K free 292380K cache Using On-Board Failure Logging The Generation 2 Fibre Channel switching modules provide the facility to log failure data to persistent storage, which can be retrieved and displayed for analysis. This on-board failure logging (OBFL) feature stores failure and environmental information in nonvolatile memory on the module. The information will help in post-mortem analysis of failed cards.
