Don't get me started on how absurd the command lengths are. =========================== ASR#show proc cpu CPU utilization for five seconds: 0%/0%; one minute: 0%; five minutes: 0% PID Runtime(ms) Invoked uSecs 5Sec 1Min 5Min TTY Process 1 2 16 125 0.00% 0.00% 0.00% 0 Chunk Manager 2 12446 402522 30 0.00% 0.00% 0.00% 0 Load Meter 3 2927 97933 29 0.00% 0.00% 0.00% 0 CDP Protocol ....
