* rt-graph: real-time plots display info popupJonathan2012-03-06
| | | | | When you hover close enough to an events time, the event name will display. This time is based on _litmus_ time, not record time.
* rt-graph: real-time tasks can be added / removed from the graphJonathan2012-03-05
| | | | Currently they copy the functionality of regular task.
* trace-cmd: Update man pages for 'check-events' optionVaibhav Nagarnaik2011-08-18
| | | | | | | | | | | | | | | There is a new option added to the 'report' target to check event formats of the events recorded in a trace data file. This patch updates the documentation in the man page. This patch also adds a new man page for 'check-events' target which verifies event formats on the local machine.

* trace-cmd: Add trace-cmd optionsSteven Rostedt2011-03-18
| | | | | | | Add trace-cmd options that reads all the plugins and lists the available options for trace-cmd report. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* trace-cmd: Add -O to trace-cmd report to pass options to pluginsSteven Rostedt2011-03-18
| | | | | | | | The -O field now passes options to the plugins. The format is of: -O [plugin:]var[=val] Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* trace-cmd: Add --func-stack option to enable function stack traceSteven Rostedt2011-03-11
| | | | | | | | | | | | | | | | | | Added --func-stack option to trace-cmd record, that will enable the function stack tracing, but only if the -l option (limit functions) is used, and succeeds in filtering functions. It is known that running the function stack trace on all functions can livelock the machine. The output now looks like this: <idle>-0 [002] 64003.696572: function: schedule <idle>-0 [002] 64003.696577: kernel_stack: <stack trace> => cpu_idle (ffffffff8100a38c) => start_secondary (ffffffff814ab828) trace-cmd-4132 [003] 64003.696632: function: schedule trace-cmd-4132 [003] 64003.696637: kernel_stack: <stack trace> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

* trace-cmd: Add trace-cmd record --date optionSteven Rostedt2011-02-24
| | | | | | | | | | | Adding the --date option to trace-cmd record (and extract) will cause trace-cmd to write a timestamp into the ftrace buffer and use it to mapped the ftrace buffer's timestamps with gettimeofday. This will allow reading of the trace.dat file to be able to convert the timestamps into actual wall time. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* trace-cmd/doc: Let environment variable override MANPAGE_DOCBOOK_XSLSteven Rostedt2011-02-01

| | | | | | | Remove space from the do_install script that was making the install of kernelshark html documents fail. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* trace-cmd/doc: Fail if manpage/docbook.xsl is not foundSteven Rostedt2011-02-01
| | | | | | | | Fail if the docbook.xsl is not found. Currently it fails if the file does not exist, but passing in a blank string does not produce an error. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* trace-cmd/restore: Allow override where debugfs/tracing and kallsyms come fromSteven Rostedt2011-01-28
| | | | | | | | | | | | Add to trace-cmd restore: -t dir: where dir is the directory to search instead of looking at debugfs/tracing -k file: where to read kallsyms from, instead of reading /proc/kallsyms Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* trace-cmd: Add -T option to report to test filtersSteven Rostedt2011-01-21
| | | | | | | Add the -T option to print the filter strings created by -F and exit. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* parse-events: Add filter on task commSteven Rostedt2011-01-14
| | | | | | | | | | | | | | | | | Add a 'COMM' special field to allow the filter in trace-cmd report to filter on the task's comm. Most records do not have data about what the comm is of the task that recorded the record. But comms are stored in various ways that parse-events can handle. By adding a special field 'COMM' (all caps) the user can now filter out tasks based on their name. This is useful when filtering out (or in) a bunch of threads. -F 'COMM != "trace-cmd"' Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* trace-cmd: Add -a option to record to record all eventsSteven Rostedt2011-01-04
| | | | | | | Add the -a option to trace-cmd record that will bring back the old behavior of recording the format of all events. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

* trace-cmd: Added trace stack commandSteven Rostedt2010-10-04
| | | | | | | | Added the command "trace-cmd stack" to run the stack tracer. It simply enables the stack tracer and depending on the options it will ouput the current stack, or disable it. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* trace-cmd: Add trace-cmd restoreSteven Rostedt2010-09-13
| | | | | | | | The restore feature now allows you to make a trace.dat file from several trace.dat.cpu.X files. This will let you put together files leftover from a crashed trace-cmd record run. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

* trace-cmd: Add -k option to keep record from resetting buffersSteven Rostedt2010-06-17
| | | | | | | | Add -k option to trace-cmd record that will keep it from resetting the buffers when it is done. This option brings back the old behavior of trace-cmd record. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* trace-cmd: Prevent latency tracer plugins from doing network tracingSteven Rostedt2010-06-11
| | | | | | | | | | The latency tracer plugins do not support network tracing. It crashes when an attempt to do a latency tracer plugin with the -N option. Simply prevent trace-cmd from performing a network trace with one of the latency tracer plugins and update the man pages. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* kernelshark: Update the HTML documentation to reflect the filter changesSteven Rostedt2010-06-10

| | | | | | | | | | | | | | | | | | | | The document is inconsistent with its use of time stamp and timestamp as well as time line and timeline. This patch changes them all to be single words, except when referencing the GUI labels which have the space.

* | build: Add DESTDIR to makeSteven Rostedt2010-06-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the variable DESTDIR that allows a user to install into a directory that will later be moved to another host. This facilitates the creation of distribution packages. make DESTDIR=/tmp/build prefix=/usr install Will install the program files into /tmp/build/usr/.. but the program will expect to find itself in the /usr/.. directories.

* | build/doc: Use a substitution reference in man pages installJohn Kacur2010-06-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | subst will substitution every occurence of a string with another. What we want here is just to substitute the last occurence. That is we want to transform files that end with .1 into .1.install We do not want to transform every ".1" in a path name into .1.install.

* | python pluginJohannes Berg2010-05-25
| | | | | | | | | | | | | | | | | | | | | | | | This adds a python plugin that can in turn load plugins written in python. To make it work, trace-cmd needs to load plugin modules with RTLD_GLOBAL so that the python interpreter's symbols will be available to python C extension modules.

* | trace-cmd/split: Force percpu when parsing by pages is setSteven Rostedt2010-05-17
|/ | | | | | | | | | | | | When parsing by pages is set, we automatically set the percpu parsing. This is because non percpu does not make sense. The CPU data is stored per page and two or more CPU data is not shared on a single CPU data page. This patch forces the -c option (percpu) when the -p option is set. Previously the -p option without the -c option gave some strange results. Usually just one or two events per page.

* build/doc: Fix removing of trace.dat(5) SYNOPSISSteven Rostedt2010-04-09
| | | | | | | | | | | | To remove the trace.dat man page "SYNOPSIS" section, the lines from: .SH "SYNOPSIS" to .sp are removed. But some systems do not add a .sp after the SYNOPSIS, so they remove the entire rest of the document. Instead of testing for .sp, test for "ignore" since that is in the document and is known to be there. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

* build: Prevent rebuild of documentation every timeSteven Rostedt2010-03-25
| | | | | | | | | | Using dependencies to trigger the manpage.xsl waring was causing all man pages to be built every time, event when no files were changed. By converting it to a funciton and calling it first, it will allow the man pages to only be rebuilt if their source files were changed. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

* trace-cmd: Add Makefile to build man pagesSteven Rostedt2010-03-08
| | | | | | | | | | | Add a Makefile that has logic to build a man page. It is still very primitive and uses ascriidoc and xsltproc to do the formating. But instead of build my own xsl file or putting together one from others, I decided to use xsl files that already exist by doing a locate on manpages/docbook.xsl, and using what is found.
