EVENTSTAT(8) System Manager's Manual EVENTSTAT(8)NAME
eventstat - a tool to measure system events.
SYNOPSIS
eventstat [-rcsv_file][-nevent_count][delay [count]]
DESCRIPTION
eventstat is a program that dumps the current active system events.
OPTIONS
eventstat options are as follow:
-h show help
-n event_count
only display the first event_count number of top events.
-q run quietly, only really makes sense with -r option.
-r csv_file
output gathered data in a comma separated values file. This can be then imported and graphed using your favourite open source spread
sheet.
-t threshold
ignore samples where the event delta per second less than the given threshold
EXAMPLES
Dump events every second until stopped.
sudo eventstat
Dump the top 20 events every 60 seconds until stopped.
sudo eventstat -n 20 60
Dump events every 10 seconds just 5 times.
sudo eventstat 10 5

PERF-TOP(1) perf Manual PERF-TOP(1)NAME
perf-top - System profiling tool.
SYNOPSIS
perf top [-e <EVENT> | --event=EVENT] [<options>]
DESCRIPTION
This command generates and displays a performance counter profile in real time.
OPTIONS -a, --all-cpus
System-wide collection. (default)
-c <count>, --count=<count>
Event period to sample.
-C <cpu-list>, --cpu=<cpu>
Monitor only on the list of CPUs provided. Multiple CPUs can be provided as a comma-separated list with no space: 0,1. Ranges of CPUs
are specified with -: 0-2. Default is to monitor all CPUS.
-d <seconds>, --delay=<seconds>
Number of seconds to delay between refreshes.
-e <event>, --event=<event>
Select the PMU event. Selection can be a symbolic event name (use perf list to list all events) or a raw PMU event (eventsel+umask) in
the form of rNNN where NNN is a hexadecimal event descriptor.
-E <entries>, --entries=<entries>
Display this many functions.
-f <count>, --count-filter=<count>
Only display functions with more events than this.
-g, --group
Put the counters into a counter group.
-F <freq>, --freq=<freq>
Profile at this frequency.
-i, --inherit
Child tasks do not inherit counters.
-k <path>, --vmlinux=<path>
Path to vmlinux. Required for annotation functionality.
-m <pages>, --mmap-pages=<pages>
Number of mmapped data pages.
-p <pid>, --pid=<pid>
Profile events on existing Process ID (comma separated list).
-t <tid>, --tid=<tid>
Profile events on existing thread ID (comma separated list).
-u, --uid=
Record events in threads owned by uid. Name or number.
-r <priority>, --realtime=<priority>
Collect data with this RT SCHED_FIFO priority.
-s <symbol>, --sym-annotate=<symbol>
Annotate this symbol.
-K, --hide_kernel_symbols
Hide kernel symbols.
-U, --hide_user_symbols
Hide user symbols.
-D, --dump-symtab
Dump the symbol table used for profiling.
-v, --verbose
Be more verbose (show counter open errors, etc).
-z, --zero
Zero history across display updates.
-s, --sort
Sort by key(s): pid, comm, dso, symbol, parent, srcline, weight, local_weight.
-n, --show-nr-samples
Show a column with the number of samples.
--show-total-period
Show a column with the sum of periods.
--dsos
Only consider symbols in these dsos.
--comms
Only consider symbols in these comms.
--symbols
Only consider these symbols.
-M, --disassembler-style=
Set disassembler style for objdump.
--source
Interleave source code with assembly code. Enabled by default, disable with --no-source.
--asm-raw
Show raw instruction encoding of assembly instructions.
-G
Enables call-graph (stack chain/backtrace) recording.
--call-graph
Setup and enable call-graph (stack chain/backtrace) recording, implies -G.
--ignore-callees=<regex>
Ignore callees of the function(s) matching the given regex. This has the effect of collecting the callers of each such function into
one place in the call-graph tree.
--percent-limit
Do not show entries which have an overhead under that percent. (Default: 0).
INTERACTIVE PROMPTING KEYS
[d]
Display refresh delay.
[e]
Number of entries to display.
[E]
Event to display when multiple counters are active.
[f]
Profile display filter (>= hit count).
[F]
Annotation display filter (>= % of total).
[s]
Annotate symbol.
[S]
Stop annotation, return to full profile display.
[z]
Toggle event count zeroing across display updates.
[qQ]
Quit.
Pressing any unmapped key displays a menu, and prompts for input.
