Detailed Description

The top entity to provide perf traces, please use this class only UNLESS you know what you are doing.

Note

You may overwrite the setPerfList function for your own interested events

Warning

only works in Linux, and make sure you have opened perf in your kernel and have the access

Note

Requires the ConfigMap Util

General set up

• create the class
• call setPerfList, You may overwrite the setPerfList function in child classes for your own interested events
• call start
• run your own process
• call end
• get the results, by getResultById, getResultByName, or resultToConfigMap

Constructor & Destructor Documentation

ThreadPerf()

INTELLI::ThreadPerf::ThreadPerf ( int  cpu )

inline

To setup this perf to specific cpu.

Parameters

cpu	>=0 for any specific cpu, =-1 for all cpu that may run this process

Member Function Documentation

getResultById()

uint64_t INTELLI::ThreadPerf::getResultById ( size_t  idx )

inline

Get the perf result by its index of PerfPair.

Parameters

idx

The index

Returns

The value

getResultByName()

uint64_t INTELLI::ThreadPerf::getResultByName ( string  name )

inline

Get the perf result by its name of of PerfPair.

Parameters

idx

The index

Returns

The value

resultToConfigMap()

ConfigMapPtr INTELLI::ThreadPerf::resultToConfigMap ( )

inline

convert the perf result into a ConfigMap

Returns

The key-value store of configMap, in shared pointer

Note

must stop after calling stop

start()

void INTELLI::ThreadPerf::start ( )

inline

To start perf tracing.

Note

call after setPerfList
