| Re: [tracecompass-dev] [v5.3.0] Question about JsonTrace module and custom parser for json files |
|
Sorry it was my bad, I solved this by select the add-ons and the jsontrace option is now available,
Now my question is about developing a custom parser for json file, since the java trace data we are creating is output in this file format. The attribute we are using might be different from JsonTrace, since it is for thread-level infomation instead of processes,
So I would like to know if it's possible to:
1. define custom event type for thread-level events so that the analysis module could recognize the event types and highlight them in charts. 2. extend (or create) another json file parser for this kind of json file.
I have looked into the class JsonTrace and TmfTrace which it extends, and think I may start from extending JsonTrace, but I would like to know your suggestions, how to better structure this?

I'm Yang and I'm doing a master thesis about visualising Java traces with TraceCompass, my supervisor is Cyrille Artho.
Currently I built TC v5.3.0 from source and was trying to import a json file, however the JsonTrace module doesn't exist, and Json Trace files cannot be recognized. Before this I was using the official release package v5.2 and it supports importing Json file, no matter it is a valid trace or not. The current problem is, the maven build log shows that all modules are built successfully, including JsonTrace.

However option "jsontrace" doesn't exist in the menu.
I look up the build configurations and there is <module> jsontrace </module> in the root pom file, but do I need to pass any parameters when building?
Looking forward to your reply and thanks in advance, once I got this solved, I have some further questions about extending class
JsonTrace and analysis of custom event types.
