Hi Golan,

This is not a HIGH CPU case.

The device is in HIGH CPU usage only when the '#' signs average upto a percentage.

eg:

                 7    112     22          82     22   2                  9
    5         31 1306056468031         55  41234233341            1 1272 1
100                                                                   *   *
90                                    *                              *   *
80                                    *                              *   *
70           *                        *                              *   *
60           *                        *                              *   *
50           *                        *                              *   *
40           *                        *                              *   *
30           *                        **                             *   **
20           *     **     **          **     **   *                  *   **
10 ###############################################
   0....5....1....1....2....2....3....3....4....4....5....5....6....6....7.
             0    5    0    5    0    5    0    5    0    5    0    5    0
                   CPU% per hour (last 72 hours)
                  * = maximum CPU%   # = average CPU%

The above example shows that the CPU utilization for the device is at an average of 10 percent, the ' * ' means we had a occasional spikes due to a few process which consume cpu for a instance.

Please let me know if this was helpful.
