Execute the following command: 23 | 24 | ```shell 25 | java -jar jstackfx-.jar 26 | ``` 27 | 28 | In order to start JStackFX and open directly a dumpTimeline file you can use the following command: 29 | 30 | ```shell 31 | java -jar jstackfx-.jar --file=/path/to/dumpTimeline.txt 32 | ``` 33 | 34 | In order to start JStackFX and make a thread dumpTimeline of a given process you can use the following command: 35 | 36 | ```shell 37 | java -jar jstackfx-.jar --pid= 38 | ``` 39 | 40 | **Warning:** if both `--pid` and `--file` parameters are used, `--file` is ignored. 41 | 42 | # Screenshot```` 43 | 44 | ![Screenshot of JStackFX](src/site/screenshots/JStackFX_01.png) 45 | ![Screenshot of JStackFX](src/site/screenshots/JStackFX_02.png) 46 | ![Screenshot of JStackFX](src/site/screenshots/JStackFX_03.png) 47 | ![Screenshot of JStackFX](src/site/screenshots/JStackFX_04.png) 48 | 49 | # Usage 50 | 51 | ## SearchingF 52 | 53 | Use the search bar in JStackFX to filter results.
