2016-02-12perf python scripting: Append examples to err msg about audit-libs-pythonTaeung Song1-1/+4
To print syscall names, the audit-libs-python package is required.. If not installed, it prints this error string: # perf script syscall-counts Install the audit-libs-python package to get syscall names. But the package name is different in Ubuntu, mention that in the error message, similar to a error message of util/trace-event-scripting.c: # perf script syscall-counts Install the audit-libs-python package to get syscall names. For example: # apt-get install python-audit (Ubuntu) # yum install audit-libs-python (Fedora) etc. Signed-off-by: Taeung Song <treeze.taeung@gmail.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Link: http://lkml.kernel.org/r/1455018790-13425-1-git-send-email-treeze.taeung@gmail.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
2016-01-06perf script: Add stat-cpi.py scriptJiri Olsa1-0/+77
Adding stat-cpi.py as an example of how to do stat scripting. It computes the CPI metrics from cycles and instructions events. The CPI is based performance metric showing the Cycles Per Instructions ratio, which helps to identify cycles-hungry code. Following stat record/report/script combinations could be used: - get CPI for given workload $ perf stat -e cycles,instructions record ls SNIP Performance counter stats for 'ls': 2,904,431 cycles 3,346,878 instructions # 1.15 insns per cycle 0.001782686 seconds time elapsed $ perf script -s ./scripts/python/stat-cpi.py 0.001783: cpu -1, thread -1 -> cpi 0.867803 (2904431/3346878) $ perf stat -e cycles,instructions record ls | perf script -s ./scripts/python/stat-cpi.py SNIP 0.001730: cpu -1, thread -1 -> cpi 0.869026 (2928292/3369627) - get CPI systemwide: $ perf stat -e cycles,instructions -a -I 1000 record sleep 3 # time counts unit events 1.000158618 594,274,711 cycles (100.00%) 1.000158618 441,898,250 instructions 2.000350973 567,649,705 cycles (100.00%) 2.000350973 432,669,206 instructions 3.000559210 561,940,430 cycles (100.00%) 3.000559210 420,403,465 instructions 3.000670798 780,105 cycles (100.00%) 3.000670798 326,516 instructions $ perf script -s ./scripts/python/stat-cpi.py 1.000159: cpu -1, thread -1 -> cpi 1.344823 (594274711/441898250) 2.000351: cpu -1, thread -1 -> cpi 1.311972 (567649705/432669206) 3.000559: cpu -1, thread -1 -> cpi 1.336669 (561940430/420403465) 3.000671: cpu -1, thread -1 -> cpi 2.389178 (780105/326516) $ perf stat -e cycles,instructions -a -I 1000 record sleep 3 | perf script -s ./scripts/python/stat-cpi.py 1.000202: cpu -1, thread -1 -> cpi 1.035091 (940778881/908885530) 2.000392: cpu -1, thread -1 -> cpi 1.442600 (627493992/434974455) 3.000545: cpu -1, thread -1 -> cpi 1.353612 (741463930/547766890) 3.000622: cpu -1, thread -1 -> cpi 2.642110 (784083/296764) Signed-off-by: Jiri Olsa <jolsa@kernel.org> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Tested-by: Kan Liang <kan.liang@intel.com> Cc: David Ahern <dsahern@gmail.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Link: http://lkml.kernel.org/r/1452077397-31958-4-git-send-email-jolsa@kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

2015-08-28perf scripts python: Add new compaction-times scriptTony Jones3-0/+317
This patch creates a new script (compaction-times) to report time spent in mm compaction. It is possible to report times in nanoseconds (default) or microseconds (-u). The option -p will break down results by process id, -pv will further decompose by each compaction entry/exit. For each compaction entry/exit what is reported is controlled by the options: -t report only timing -m report migration stats -ms report migration scanner stats -fs report free scanner stats The default is to report all. Entries may be further filtered by pid, pid-range or comm (regex). The script is useful when analysing workloads that compact memory. The most common example will be THP allocations on systems with a lot of uptime that has fragmented memory. This is an example of using the script to analyse a thpscale from mmtests which deliberately fragments memory and allocates THP in 4 separate threads # Recording step, one of the following; $ perf record -e 'compaction:mm_compaction_*' ./workload # or: $ perf script record compaction-times # Reporting: basic total: 2444505743ns migration: moved=357738 failed=39275 free_scanner: scanned=2705578 isolated=387875 migration_scanner: scanned=414426 isolated=397013 # Reporting: Per task stall times $ perf script report compaction-times -- -t -p total: 2444505743ns 6384[thpscale]: 740800017ns 6385[thpscale]: 274119512ns 6386[thpscale]: 832961337ns 6383[thpscale]: 596624877ns # Reporting: Per-compaction attempts for task 6385 $ perf script report compaction-times -- -m -pv 6385 total: 274119512ns migration: moved=14893 failed=24285 6385[thpscale]: 274119512ns migration: moved=14893 failed=24285 6385[thpscale].1: 3033277ns migration: moved=511 failed=1 6385[thpscale].2: 9592094ns migration: moved=1524 failed=12 6385[thpscale].3: 2495587ns migration: moved=512 failed=0 6385[thpscale].4: 2561766ns migration: moved=512 failed=0 6385[thpscale].5: 2523521ns migration: moved=512 failed=0 ..... output continues ...

2014-10-29perf script: Add Python script to export to postgresqlAdrian Hunter3-0/+392
Add a Python script to export to a postgresql database. The script requires the Python pyside module and the Qt PostgreSQL driver. The packages needed are probably named "python-pyside" and "libqt4-sql-psql" The caller of the script must be able to create postgresql databases. The script takes the database name as a parameter. The database and database tables are created. Data is written to flat files which are then imported using SQL COPY FROM.

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.

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.

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.
