The comparison between traced and symbol addresses is backwards: if the traced address doesn't exactly match a symbol (which we don't expect it to), we'll show the next symbol and the offset to it, whereas we should show the previous symbol and the offset from it.

2013-02-06perf perl scripts: Fix SIGALRM and pipe read race for rwtopJiri Olsa1-1/+5
Fixing rwtop script race. The issue is caused by rwtop script triggering SIGALRM and underneath pipe reading layer reporting error when interrupted. Fixing this by setting SA_RESTART for rwtop SIGALRM handler, which avoids interruption of the pipe reading layer.

2012-08-08perf scripts python: Add event_analyzing_sample.py as a sample for general ↵Feng Tang1-0/+193
event handling Currently only trace point events are supported in perf/python script, the first 3 patches of this serie add the support for all types of events. This script is just a simple sample to show how to gather the basic information of the events and analyze them. This script will create one object for each event sample and insert them into a table in a database, then leverage the simple SQL commands to sort/group them. User can modify or write their brand new functions according to their specific requirment. Here is the sample of how to use the script: $ perf record -a tree $ perf script -s process_event.py There is 100 records in gen_events table Statistics about the general events grouped by thread/symbol/dso: comm number histgram ========================================== swapper 56 ###### tree 20 ##### perf 10 #### sshd 8 #### kworker/7:2 4 ### ksoftirqd/7 1 # plugin-containe 1 # symbol number histgram ========================================================== native_write_msr_safe 40 ###### __lock_acquire 8 #### ftrace_graph_caller 4 ### prepare_ftrace_return 4 ### intel_idle 3 ## native_sched_clock 3 ## Unknown_symbol 2 ## do_softirq 2 ## lock_release 2 ## lock_release_holdtime 2 ## trace_graph_entry 2 ## _IO_putc 1 # __d_lookup_rcu 1 # __do_fault 1 # __schedule 1 # _raw_spin_lock 1 # delay_tsc 1 # generic_exec_single 1 # generic_fillattr 1 # dso number histgram ================================================================== [kernel.kallsyms] 95 ####### /lib/libc-2.12.1.so 5 ### Signed-off-by: Feng Tang <feng.tang@intel.com> Cc: Andi Kleen <andi@firstfloor.org> Cc: David Ahern <dsahern@gmail.com> Cc: Ingo Molnar <mingo@elte.hu> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Robert Richter <robert.richter@amd.com> Cc: Stephane Eranian <eranian@google.com> Link: http://lkml.kernel.org/r/1344419875-21665-6-git-send-email-feng.tang@intel.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

2011-09-29perf script: Add drop monitor scriptNeil Horman3-0/+78
A while back I created the dropmonitor protocol, which allowed users to get reports of dropped frames communicated to them via a netlink socket. While useful, several people have now asked that I integrate the ability to do drop monitoring with perf, so they don't have to run additional tools. This patch adds a drop monitor script to the perf suite, and provides the same output that the netlink socket does.

2010-09-07perf: Add a script to show packets processingKoki Sanagi3-0/+477
Add a perf script which shows packets processing and processed time. It helps us to investigate networking or network devices. If you want to use it, install perf and record perf.data like following. If you set script, perf gathers records until it ends. If not, you must Ctrl-C to stop recording. And if you want a report from record, If you use some options, you can limit the output. Option is below. tx: show only tx packets processing rx: show only rx packets processing dev=: show processing on this device debug: work with debug mode. It shows buffer status. For example, if you want to show received packets processing associated with eth4, 106133.171439sec cpu=0 irq_entry(+0.000msec irq=24:eth4) | softirq_entry(+0.006msec) | |---netif_receive_skb(+0.010msec skb=f2d15900 len=100) | | | skb_copy_datagram_iovec(+0.039msec 10291::10291) | napi_poll_exit(+0.022msec eth4) This perf script helps us to analyze the processing time of a transmit/receive sequence.

2010-08-02perf, sched migration: Handle ignored migrate out eventsFrederic Weisbecker1-1/+4
Migrate out events may happen on tasks that are not in the runqueue, for example this is the case for tasks that are sleeping. In this case, we don't want to log the migrate out event in the source runqueue because the task is not eventually in the runqueue and we have already logged its sleep event. This fixes timeslices that spuriously propagate a sleep event from the previous timeslice.

2010-08-02perf: New migration tool overviewFrederic Weisbecker3-0/+639
This brings a GUI tool that displays an overview of the load of tasks proportion in each CPUs. The CPUs forward progress is cut in timeslices. A new timeslice is created for every runqueue event: a task gets pushed out or pulled in the runqueue. For each timeslice, every CPUs rectangle is colored with a red power that describes the local load against the total load. This more red is the rectangle, the higher is the given CPU load. This load is the number of tasks running on the CPU, without any distinction against the scheduler policy of the tasks, for now. Also for each timeslice, the event origin is depicted on the CPUs that triggered it using a thin colored line on top of the rectangle timeslice. These events are: * sleep: a task went to sleep and has then been pulled out the runqueue. The origin color in the thin line is dark blue. * wake up: a task woke up and has then been pushed in the runqueue. The origin color is yellow. * wake up new: a new task woke up and has then been pushed in the runqueue. The origin color is green. * migrate in: a task migrated in the runqueue due to a load balancing operation. The origin color is violet. * migrate out: reverse of the previous one. Migrate in events usually have paired migrate out events in another runqueue. The origin color is light blue. Clicking on a timeslice provides the runqueue event details and the runqueue state. The CPU rectangles can be navigated using the usual arrow controls. Horizontal zooming in/out is possible with the "+" and "-" buttons.

2010-06-01perf scripts python: Give field dict to unhandled callbackPierre Tardy1-2/+1
trace_unhandled() callback does not allow to access event fields, this patch resolves the problem. It can also been used as a more pythonic and flexible way for script writters to demux event types This will for example greatly simplify pytimechart event demux.

2010-04-14perf trace/scripting: Enable scripting shell scripts for live modeTom Zanussi16-16/+47
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.

2010-04-14perf trace/scripting: Add rwtop and sctop scriptsTom Zanussi8-0/+315
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.
