   @summary{@keys}=$sb->summary(@keys);
    This method iterates over all workers and collects summary activity.

    The following keys are recognized:

    "_" count the number of workers in "Waiting for Connection" state

    "S" count the number of workers in "Starting up" state

    "R" count the number of workers in "Reading Request" state

    "W" count the number of workers in "Sending Reply" state

    "K" count the number of workers in "Keepalive (read)" state

    "D" count the number of workers in "DNS Lookup" state

    "C" count the number of workers in "Closing connection" state

    "L" count the number of workers in "Logging" state

    "G" count the number of workers in "Gracefully finishing" state

    "I" count the number of workers in "Idle cleanup of worker" state

    "." count the number of open slots with no current worker

    "cw"
        the current number of active workers. For prefork-MPM this is the
        number of apache worker processes currently running. Number of
        workers in any state except for ".", "S" and "I".

    "bw"
        current number of busy workers. Any worker in a state except for
        ".", "S", "I", "_" is busy.

    "iw"
        current number of idle workers ("_" state).

    "nr"
        overall number of requests served so far, sum(access_count).

    "nb"
        overall number of bytes served so far, sum(bytes_served).
