## Name
|
|
|
|
Profiler - Serenity process profiler
|
|
|
|
## Synopsis
|
|
|
|
```**sh
|
|
$ Profiler [--pid PID] [perfcore-file]
|
|
```
|
|
|
|
## Description
|
|
|
|
Profiler facilitates process performance profiling and provides a GUI offering
|
|
visual graph and tree representations to easily navigate generated profiling
|
|
information.
|
|
|
|
If no arguments are provided, a window containing a list of running processes
|
|
is presented, allowing a process to be selected for profiling.
|
|
|
|
Profiling information is written to `perfcore.<pid>` in the working directory
|
|
and opened immediately for browsing following termination of profiling.
|
|
|
|
Profiler can also load performance information from previously created
|
|
`perfcore` files.
|
|
|
|
## Options

|
|
|
* `-p PID`, `--pid PID`: PID to profile
|
|
|
|
## Arguments
|
|
|
|
* `perfcore-file`: Path of perfcore file to load
|
|
|
|
## Examples

|
|
|
