...ay that many stock exchange data feeds are provided over UDP - including some that are in the 10s of MBits/sec range today, and are predicted to move into the 100s of MBits/sec range soon. Consuming these feeds is a latency-critical business and good diagnostic tools are vital. -- Philip Beevers Fidessa Infrastructure Development mailto:philip.beevers at fidessa.com phone: +44 1483 206571 ******************************************************************************************************************************************************************************************** This message is inten...

hi, I am trying to find out the avg cpu time spent in each of my user methods (exclusive of other methods invoked by a method). Hence the following snippet failed miserably: ----------------------- pid$target:a.out::entry { time[probefunc] = timestamp;} pid$target:a.out::return { @spent[probefunc] = avg(timestamp - time[probefunc]);} END { printa(@spent);}

Tracing Fans, I know it''s been a long time in coming but the CPU Performance Counter (CPC) provider is almost here! The code is currently in for review and a proposed architecture document is attached here for review. Any and all feedback/questions on the proposed implementation is welcome. Thanks.

...good example of using libumem to track leaks; looking for bad memory access is similar. However, once you''ve narrowed down where your crash might be, DTrace and particularly speculations are very powerful tools for providing more information about the crash scenario. -- Philip Beevers Fidessa Infrastructure Development mailto:philip.beevers at fidessa.com phone: +44 1483 206571 ****************************************************************** This message is intended only for the stated addressee(s) and may be confidential.

...the different orders? e.g. printa() for sort by sample, printak() for sort by key. My reason for wanting to do both in the same script is that the current printa() ordering is nearly always right; it''s relatively (although very useful in those cases) to order by key. -- Philip Beevers Fidessa Infrastructure Development mailto:philip.beevers at fidessa.com phone: +44 1483 206571 > -----Original Message----- > From: dtrace-discuss-bounces at opensolaris.org > [mailto:dtrace-discuss-bounces at opensolaris.org]On Behalf Of Bryan > Cantrill > Sent: 15 September 2005 07:29 &...
