Upload linux perf command results (#3349)
* generate .perf trace * change order * tmp * check * ooo * specify file * check * aaa * install perf * add * install perf * add to log.ps1 * add * odebug print * print output * add loop to wait collection * small sampling rate * print info * gen svg * fix typo * fix perf install trigger * chmod to flamegraph scripts and add debug output * fix count variable access. use @ instead of $ * try catch perf * debug print * print from remote * more debug * add -ErrorAction Continue * error oput * use original * wrap * DebugPreference Continue * stop server side PerfGraph * explicitly install flamegraph tools * set path for flamegraaph tools * fix file existence check * gset perf paranoid * setup flamegraph tools just before using * add sudo * sudo for perf * add sudo for all perf * check permissions * pass environment variables * set explicit library path * enable server perf tracing * output details for remote exe * stop server perf trace * remove original LD_LIBRARY_PATH * show out of memory * remove comment, enable server * fix directory name * commenting * oops * Fix tar error * remove Write-Debug as it is critical issue * fix SmbDir for linux * stop debug print * add throw for Perf function * Use max sampling frequency for perf with workaround * upload perf txt file for WPA visualization * add documents * add images * fix data extension * smaller freq * cleanup before perf run * add Path check * delete file for each type * reduce sampling freq. addpending work * use safer file name based operation * parallelize client perf post processing * reduce freq and parallelize server/client post proccessing * increase timeout for perf measurement * add cancel func * change timeout to 90min * fix tab * Fix Loopback server side warning * adjust for throughput tests

On Linux, MsQuic leverages [LTTng](https://lttng.org/features/) for its logging. Some dependencies, such as babeltrace, lttng, and clog2text_lttng are required. The simplest way to install all dependencies is by running `./scripts/prepare-machine.ps1 -ForTest`, but if you only want to collect the traces on the machine, the **minimal dependencies** are:

## Call stacks and CPU Usage
|
||||
|
||||
### Windows
|
||||
|
||||
|
||||
One of the built-in capabilities of WPA is the ability to analyze CPU trace information to see the CPU usage of the various call stacks in the code. For instance, in the above Flame Graph you can easily see that the most expensive function (58% of total CPU usage!) is `CxPlatEncrypt`.
|
||||
|
||||
### Linux
|
||||
Linux perf command is one of the way to collect such information.
|
||||
```sh
|
||||
# on Linux
|
||||
sudo apt-get install -y linux-tools-`uname -r`
|
||||
# use your own options
|
||||
perf record -a -g -F 10 -o out.perf.data
|
||||
# ".perf.data.txt" extension is required for later visualize on WPA
|
||||
perf script -i out.perf.data > out.perf.data.txt
|
||||
```
|
||||
|
||||
#### Visualize perf artifact on WPA
|
||||
The perf command's artifact can be visualized on Windows through WPA.
|
||||
Follow steps below to load perf extension on WPA.
|
||||
|
||||
```pwsh
|
||||
# on Windows
|
||||
cd ${WORKDIR}
|
||||
git clone https://github.com/microsoft/Microsoft-Performance-Tools-Linux-Android
|
||||
cd .\Microsoft-Performance-Tools-Linux-Android\PerfDataExtensions
|
||||
dotnet build
|
||||
# use absolute path
|
||||
wpa.exe -addsearchdir ${WORKDIR}\Microsoft-Performance-Tools-Linux-Android\PerfDataExtensions\bin\Debug\netstandard2.1\
|
||||
# Open out.perf.data.txt on WPA. You might need to open multiple time if you see error at opening (known issue?)
|
||||
```
|
||||
Change visualization type by drop down menu as shown in image below. Also you can filter in data for each CPU etc.

||||
