This is the command perf-inject that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
PROGRAM:
NAME
perf-inject - Filter to augment the events stream with additional information
SYNOPSIS
perf inject <options>
DESCRIPTION
perf-inject reads a perf-record event stream and repipes it to stdout. At any point the
processing code can inject other events into the event stream - in this case build-ids (-b
option) are read and injected as needed into the event stream.
Build-ids are just the first user of perf-inject - potentially anything that needs
userspace processing to augment the events stream with additional information could make
use of this facility.
OPTIONS
-b, --build-ids=
Inject build-ids into the output stream
-v, --verbose
Be more verbose.
-i, --input=
Input file name. (default: stdin)
-o, --output=
Output file name. (default: stdout)
-s, --sched-stat
Merge sched_stat and sched_switch for getting events where and how long tasks slept.
sched_switch contains a callchain where a task slept and sched_stat contains a
timeslice how long a task slept.
--kallsyms=<file>
kallsyms pathname
--itrace
Decode Instruction Tracing data, replacing it with synthesized events. Options are:
i synthesize instructions events
b synthesize branches events
c synthesize branches events (calls only)
r synthesize branches events (returns only)
x synthesize transactions events
e synthesize error events
d create a debug log
g synthesize a call chain (use with i or x)
l synthesize last branch entries (use with i or x)
The default is all events i.e. the same as --itrace=ibxe
In addition, the period (default 100000) for instructions events
can be specified in units of:
i instructions
t ticks
ms milliseconds
us microseconds
ns nanoseconds (default)
Also the call chain size (default 16, max. 1024) for instructions or
transactions events can be specified.
Also the number of last branch entries (default 64, max. 1024) for
instructions or transactions events can be specified.
--strip
Use with --itrace to strip out non-synthesized events.
