truncating aggregation output only
Hello dtrace-discuss, Sometimes I want to run a script for some time and every n second output N top entries. trunc() isn''t suitable here as it also removed keys/values. I want it ''coz over time if I use sum() entries which are normally truncated can actually get to top over a time. Maybe printa() extension, something like: printa(@b[10]) - to output top 10? --

Can I use printa() for printing multiple agg regations?
Hi Bryan, > Does that sit well with everyone? Seems fine to me. Just revisiting one of Dragan''s points, though (sorry if I missed the answer) - is there a reason for making this global (via a #pragma) rather than, say, simply providing two functions which print in the different orders? e.g. printa() for sort by sample, printak() for sort by key. My reason for wanting to do both in

sched provider
Hi All, I used the following script from the dtrace manual to measure how long a particular process runs on the cpu. Modified it to look at the exact timestamps: [i] sched:::on-cpu { self->ts = timestamp; printf("on=%d\n", self->ts) } sched:::off-cpu /self->ts/ { printf("off=%d\n", timestamp) self->ts = 0; } [/i] The output looks like this: [i]on=24591 off=24603

printa stddev error
Hi, Searched for similar errors and nothing came up. Anybody know what this is? When using aggregate stddev, and then trying to print it at END, using printa, I get this error: dtrace: processing aborted: Invalid return value from callback avg works fine. Tried on two recent builds of solaris (build 89 and build 94), on two difference sparc systems. Here''s a sample script:

why dtrace is not quiet?
i''m running the following script: #pragma D option quiet profile:::tick-1sec / ++x >= 15 / { exit(0); } io:::start { @io_size[execname] = sum(args[0]->b_bcount); } on exit, the script prints out the value of @io_size, why? there''s no printa(), and i also specified "D option quiet" (i also tried -q). this seems to happen with any kind of probe: on exit(0) all

Monitoring filessytem access
When somebody is hammering on the system, I want to be able to detect who''s doing it, and hopefully even what they''re doing. I can''t seem to find any way to do that. Any suggestions? Everything I can find ... iostat, nfsstat, etc ... AFAIK, just show me performance statistics and so forth. I''m looking for something more granular. Either *who* the

profile provider: is it me doing stupid things?
Just showing someone how great DTrace is and then we spot something I do not understand. Of course it can be a major misunderstanding of myself. Would appreciate another (expert) look upon this. The goal we try to achieve is trying to get insight if there is a bursty nature in the time slot when system calls are done. Following DTrace snippet is tried: dtrace -q -p 3173 -n

getting hex out of ints
I have a probe: pid111::myfunc:entry { self->arg = arg0; } pid111::myfunc:return /self->arg/ { @[self->arg] = quantize(); } works great, but i''d like arg0 to be printed in hex. I''ve tried numerous approaches to do this but i''ve hit a wall every time. I''ve tried: 1) self->arg = sprintf(arg0); no, cuz dtrace has no sprintf 2) self->arg

dtrace overhead and proper measuring technique
I''m trying to time a function within Firefoxwith a pid$target probe [2]. e.g dtrace -Zqw -x dynvarsize=64m -x evaltime=preinit -p 13954 -s menu- construct.d -s sigcont.d elapsed: 12.7942481ms cpu : 7.7911194ms count : 40 times I''m also measuring Firefox startup time by running it arguments like this: ... file:///Users/joelr/work/mozilla/startup/startup.html#`python

Extending lwpsinfo_t with pr_lgrp for DTrace consumers
The sched provider defines the stable "lgrp" variable that is the lgroup of the current CPU. This is mostly interesting when we can compare it with the actual thread home lgroup, so I''d like to extend the lwpsinfo_t structure with the new pr_lgrp field which will be implemented using translator. This will match the addition of the pr_lgrp field to the proc(4) lwpsinfo_t

hotuser in multicore system
Incase of multi-core systems where multiple threads maybe scheduled for execution, does the below dscript (from hotuser in DTraceToolkit) collect information for multiple libraries/functions that would be getting executed at a given point of time. I have been able to test it to check if it does or doesn''t. I assume it does. This was a query I have about profiling in general. #pragma D

truncating aggregation output
Hi, there was discussion on "truncating aggregation output only" (http://www.opensolaris.org/jive/thread.jspa?messageID=19008) on DTrace forum. From what was discussed the aggregation options like aggsortrev, aggsortkey, aggsortpos, aggsortkeypos are already available (Thanks Bryan!). I am wondering what are current plans for ''aggtop'' option (or
