It also displays the total usage since the start of<b><i><a href="./usrLib.html#spy">spy</a></i>( )</b> (or the last call to <b><i><a href="./usrLib.html#spyClkStart">spyClkStart</a></i>( )</b>), and the change in usage sincethe last <b><i><a href="./usrLib.html#spyReport">spyReport</a></i>( )</b>.<p>CPU usage can also be monitored manually by calling <b><i><a href="./usrLib.html#spyClkStart">spyClkStart</a></i>( )</b> and<b><i><a href="./usrLib.html#spyReport">spyReport</a></i>( )</b>, instead of <b><i><a href="./usrLib.html#spy">spy</a></i>( )</b>. In this case, <b><i><a href="./usrLib.html#spyReport">spyReport</a></i>( )</b> provides a one-timereport of the same information provided by <b><i><a href="./usrLib.html#spy">spy</a></i>( )</b>.<p>Data is gathered by an interrupt-level routine that is connected by<b><i><a href="./usrLib.html#spyClkStart">spyClkStart</a></i>( )</b> to the auxiliary clock. Currently, this facility cannot beused with CPUs that have no auxiliary clock. Interrupts that are at ahigher level than the auxiliary clock's interrupt level cannot bemonitored.<p>All user interface routine except <b><i><a href="./spyLib.html#spyLibInit">spyLibInit</a></i>( )</b> are available through usrLib.<p></blockquote><h4>EXAMPLE</h4><blockquote><p>The following call:<pre> -> spy 10, 200</pre>will generate a report in the following format every 10 seconds,gathering data at the rate of 200 times per second.<pre>NAME ENTRY TID PRI total % (ticks) delta % (ticks)-------- -------- ----- --- --------------- ---------------tExcTask _excTask fbb58 0 0% ( 0) 0% ( 0)tLogTask _logTask fa6e0 0 0% ( 0) 0% ( 0)tShell _shell e28a8 1 0% ( 4) 0% ( 0)tRlogind _rlogind f08dc 2 0% ( 0) 0% ( 0)tRlogOutTask _rlogOutTa e93e0 2 2% ( 173) 2% ( 46)tRlogInTask _rlogInTas e7f10 2 0% ( 0) 0% ( 0)tSpyTask _spyTask ffe9c 5 1% ( 116) 1% ( 28)tNetTask _netTask f3e2c 50 0% ( 4) 0% ( 1)tPortmapd _portmapd ef240 100 0% ( 0) 0% ( 0)KERNEL 1% ( 105) 0% ( 10)INTERRUPT 0% ( 0) 0% ( 0)IDLE 95% ( 7990) 95% ( 1998)TOTAL 99% ( 8337) 98% ( 2083)</pre>The "total" column reflects CPU activity since the initial call to <b><i><a href="./usrLib.html#spy">spy</a></i>( )</b>or the last call to <b><i><a href="./usrLib.html#spyClkStart">spyClkStart</a></i>( )</b>.
