systrace doesn't include JS or native modules thread info

[evelant]

I'm using systrace via the process detailed in the documentation. In my trace results there is no useful JS thread or native modules thread info. This makes it more or less useless for profiling my app.

React native version:

System:
    OS: macOS 10.14.6
    CPU: (12) x64 Intel(R) Core(TM) i7-8750H CPU @ 2.20GHz
    Memory: 791.28 MB / 16.00 GB
    Shell: 3.2.57 - /bin/bash
  Binaries:
    Node: 8.11.3 - ~/.nvm/versions/node/v8.11.3/bin/node
    Yarn: 1.17.3 - ~/.yarn/bin/yarn
    npm: 6.10.1 - ~/.nvm/versions/node/v8.11.3/bin/npm
    Watchman: 4.9.0 - /usr/local/bin/watchman
  SDKs:
    iOS SDK:
      Platforms: iOS 12.4, macOS 10.14, tvOS 12.4, watchOS 5.3
  IDEs:
    Android Studio: 3.4 AI-183.5429.30.34.5452501
    Xcode: 10.3/10G8 - /usr/bin/xcodebuild
  npmPackages:
    @react-native-community/cli: ^2.9.0 => 2.9.0 
    react: 16.9.0 => 16.9.0 
    react-native: ^0.60.5 => 0.60.5 
  npmGlobalPackages:
    create-react-native-app: 2.0.2
    react-native-macos-cli: 2.0.1

Steps To Reproduce

1. Take a systrace profile per the documentation
2. Open profile and note that the JS and native modules threads don't contain useful information like they do in the documentation example

Describe what you expected to happen:
JS and native modules threads appear in the systrace as per the documentation. See the following screenshots of my trace -- the JS and native modules information is missing. There is mqt_js and mqt_native_mod in the trace but they don't contain any meaningful data like the documentation example. This trace definitely contains some heavy JS work but it appears like it isn't recorded.

It looks like you are using an older version of React Native. Please update to the latest release, v0.60 and verify if the issue still exists.

The "Resolution: Old Version" label will be removed automatically once you edit your original post with the results of running `react-native info` on a project using the latest release.

I updated to latest react native. Problem still persists, there is no useful information about the js or native modules threads like is shown in the documentation. A trace file can be found here: https://www.dropbox.com/s/n0ig26bctwq359k/trace.html?dl=0

The issue does conform to the template...?

Anything I can do here? The bot seems to have erroneously confined my issue to the dustbin.

This issue never got examined. I think it got ignored because the bot flagged it as needs more information even though I provided the info. Needs discussion.
