# hsperfdata-parser
`hsperfdata-parser` is an application for parsing and analyzing `hsperfdata` files from a Java application. It can obtain a snapshot of the `hsperfdata` file of a Java process in real-time using its PID or you can import the file manually instead.
> `hsperfdata` is a performance monitoring file that is created when a Java application opens and is deleted once the process terminates.
> In Windows, these files are located inside %temp% in the `hsperfdata_%username%` folder. The name of each file inside it represents the PID of a Java process.
## Pre-requisites
- Java 8
## Usage
```shell
$ java -jar hsperfparser.jar
```
