perf/trace/scripting: rwtop script cleanup

2010-05-10T22:50:56Z

A couple of fixes for the rwtop script: - printing the totals and clearing the hashes in the signal handler eventually leads to various random and serious problems when running the rwtop script continuously. Moving the print_totals() calls to the event handlers solves that problem, and the event handlers are invoked frequently enough that it doesn't affect the timeliness of the output. - Fix nuisance 'use of uninitialized value' warnings Cc: Frédéric Weisbecker Cc: Ingo Molnar Message-Id: <1273466820-9330-4-git-send-email-tzanussi@gmail.com> Signed-off-by: Tom Zanussi Signed-off-by: Arnaldo Carvalho de Melo

perf: Remove leftover useless options to record trace events from scripts

2010-04-30T17:55:00Z

-f, -c 1, -R are now useless for trace events recording, moreover -M is useless and event hurts. Remove them from the documentation examples and from record scripts.

perf trace/scripting: Enable scripting shell scripts for live mode

2010-04-14T09:56:08Z

It should be possible to run any perf trace script in 'live mode'. This requires being able to pass in e.g. '-i -' or other args, which the current shell scripts aren't equipped to handle. In a few cases, there are required or optional args that also need special handling. This patch makes changes the current set of shell scripts as necessary.

perf trace/scripting: Add rwtop and sctop scripts

2010-04-14T09:56:08Z

A couple of scripts, one in Python and the other in Perl, that demonstrate 'live mode' tracing. For each, the output of the perf event stream is fed continuously to the script, which continuously aggregates the data and reports the current results every 3 seconds, or at the optionally specified interval. After the current results are displayed, the aggregations are cleared and the cycle begins anew. To run the scripts, simply pipe the output of the 'perf trace record' step as input to the corresponding 'perf trace report' step, using '-' as the filename to -o and -i: $ perf trace record sctop -o - | perf trace report sctop -i - Also adds clear_term() utility functions to the Util.pm and Util.py utility modules, for use by any script to clear the screen.

perf/scripts: Add syscall tracing scripts

2010-02-25T03:07:48Z

Adds a set of scripts that aggregate system call totals and system call errors. Most are Python scripts that also test basic functionality of the new Python engine, but there's also one Perl script added for comparison and for reference in some new Documentation contained in a later patch.

perf/scripts: Remove check-perf-trace from listed scripts

2010-02-23T19:58:59Z

The check-perf-trace script only checks Perl functionality, and doesn't really need to be listed as as user script anyway. This only removes the '-report' shell script, so although it doesn't appear in the listing, the '-record' shell script and the check perf trace perl script itself is still available and can still be run manually as such: $ libexec/perf-core/scripts/perl/bin/check-perf-trace-record $ perf trace -s libexec/perf-core/scripts/perl/check-perf-trace.pl Signed-off-by: Tom Zanussi Cc: Ingo Molnar Cc: Steven Rostedt Cc: Keiichi KII Cc: Peter Zijlstra Cc: Paul Mackerras Cc: Arnaldo Carvalho de Melo LKML-Reference: <1264580883-15324-6-git-send-email-tzanussi@gmail.com> Signed-off-by: Frederic Weisbecker
