Something too complex; I fear I won't ever have enough time to try it and figure out how to apply it for it to be of any use for me.

I wish there was a simpler and quicker introduction into the tool's capabilities than an hour long video and a text article saying it's a swiss army knife that does a lot of things. I need 1 or a few glimpses into it, there's no need to cover every capability thoroughly, show just enough to have some general understanding of how it works and how to use it and how to solve some common problems with it.

Go to https://ui.perfetto.dev/. On the left sidebar, under "Example traces", click "Open Android example".

For a simple example using your own data, save this as a file and open it via "Open trace file":

  [
    {"name": "Example 1", "ph": "X", "ts": 1, "dur": 1, "pid": 0, "tid": 0},
    {"name": "Example 2", "ph": "X", "ts": 3, "dur": 2, "pid": 0, "tid": 0},
    {"name": "Example 3", "ph": "X", "ts": 2, "dur": 1, "pid": 0, "tid": 1},
    {"name": "Example 4", "ph": "X", "ts": 4, "dur": 2, "pid": 0, "tid": 1}

This talk was meant to be a comprehensive look into the tool for an audience familiar with performance and tracing (but not necessarily Perfetto and how it can be used on Linux).

If you're more looking for a short intro, I'd maybe suggest our docs website, specifically the page https://perfetto.dev/docs/getting-started/start-using-perfet...

For example:

* if you work in the Linux kernel, try https://perfetto.dev/docs/getting-started/start-using-perfet...

* If you're generally curious about performance or tracing try https://perfetto.dev/docs/getting-started/start-using-perfet...

There's also our quick starts which take you through "I just want to see the tool in action". Find the system tracing one at https://perfetto.dev/docs/getting-started/system-tracing

That's just the nature of these tools though. For example, Windows has its own powerful ETW tracing framework, but using it for real profiling and debugging requires learning a lot about the tools: https://randomascii.wordpress.com/2015/09/24/etw-central/
