tapset::perf - systemtap perf probe points
DESCRIPTION
This family of probe points is used to probe "perf events" on suitably configured kernels (2.6.33+). It contains a number of aliases for
the ABI-specified event type/config tuples.
The default sampling interval of the translator(1000000) is not overridden, so some of these probe points may fire very infrequently. Use
the lower level perf.type(AA).config(BB).sample(CC) probe point if this is a problem.
perf.hw.*
A variety of hardware events, as generalized by the kernel. These generally require running on bare hardware with selected proces-
sors.
probe perf.hw.cpu_cycles
probe perf.hw.instructions
probe perf.hw.cache_references
probe perf.hw.cache_misses
probe perf.hw.branch_instructions
probe perf.hw.branch_misses
probe perf.hw.bus_cycles
perf.sw.*
Special "software" events provided by the kernel. These sometimes work in virtualized environments and with more processor archi-
tectures.
probe perf.sw.cpu_clock
probe perf.sw.task_clock
probe perf.sw.page_faults
probe perf.sw.context_switches
probe perf.sw.cpu_migrations
probe perf.sw.page_faults_min
probe perf.sw.page_faults_maj
probe perf.sw.alignment_faults
probe perf.sw.emulation_faults
perf.hw_cache.TYPE.ACCESS.RESULT
Hardware cache events, where available. A subset of the following cartesian product may be available:
probe perf.hw_cache.l1d.*.*
probe perf.hw_cache.l1i.*.*
probe perf.hw_cache.ll.*.*
probe perf.hw_cache.dtlb.*.*
probe perf.hw_cache.itlb.*.*
probe perf.hw_cache.bpu.*.*
probe perf.hw_cache.*.read.*
probe perf.hw_cache.*.write.*
probe perf.hw_cache.*.prefetch.*
probe perf.hw_cache.*.*.access
probe perf.hw_cache.*.*.miss

PERF-SCHED(1) perf Manual PERF-SCHED(1)NAME
perf-sched - Tool to trace/measure scheduler properties (latencies)
SYNOPSIS
perf sched {record|latency|map|replay|script}
DESCRIPTION
There are five variants of perf sched:
'perf sched record <command>' to record the scheduling events
of an arbitrary workload.
'perf sched latency' to report the per task scheduling latencies
and other scheduling properties of the workload.
'perf sched script' to see a detailed trace of the workload that
was recorded (aliased to 'perf script' for now).
'perf sched replay' to simulate the workload that was recorded
via perf sched record. (this is done by starting up mockup threads
that mimic the workload based on the events in the trace. These
threads can then replay the timings (CPU runtime and sleep patterns)
of the workload as it occurred when it was recorded - and can repeat
it a number of times, measuring its performance.)
'perf sched map' to print a textual context-switching outline of
workload captured via perf sched record. Columns stand for
individual CPUs, and the two-letter shortcuts stand for tasks that
are running on a CPU. A '*' denotes the CPU that had the event, and
a dot signals an idle CPU.
OPTIONS -i, --input=<file>
Input file name. (default: perf.data unless stdin is a fifo)
-v, --verbose
Be more verbose. (show symbol address, etc)
-D, --dump-raw-trace=
Display verbose dump of the sched data.

Hi all,
everytime the sun fire server reboots in always boots to the probe menu. This needs to be manually booted by command named boot.
Is there a boot file somewhere on the system that changes the boot script to boot fully not to the probe menu. (2 Replies)
I have run init 0 to bring it to OK prompt.

Hi guys,
I was asked to setup an Ultra60 (Sol 8) with an StorEdge A1000. Does anyone know if a probe-scsi-all is suppose to detect it? Right now it doesn't, so maybe I answered my own question :rolleyes:
We have an the same setup running already, but I wasn't around when that was setup.

I am VERY new to unix and I have a application (ASG Cypress) that we need to monitor with Tivoli Omnibus using the probe mttrapd.
The issue is port 161. I was told that you can use snmpdx to master over the port and then redirect incoming traps to their rspected probes.

Hello everyone,
I am trying to label the X axis of a plot, using the Greek letter 'nu' within it.
So I have:
ax.set_xlabel('Energy ($ h \nu $) / eV') all the other Greek letters I have tried work perfectly this way, as in LaTex, but with \nu, apparently it recognizes \n as 'new line' and I end... (2 Replies)

Trying to match $1 in output.txt with $1 probe.txt, when a match is found in $6 of probe.txt the text in $5 of output is copied.
For example, the first record in output.txt is A_16_P32713632 and that matches row 19318 in probe.txt, so in the 6 field (after 0.940798) of row 19318 ACTA2 is... (4 Replies)
