Idea: Generate memory flamegraph with inferno

[pothos]

Hello,
maybe the most things for this are already in place and it's easy to do.
Currently manual usage of the heaptrack GUI is needed to see the memory flamegraph. Inferno could be used to directly generate an interactive SVG by exporting a perf-compatible text format (the text format can even be without collapsed stacks, as there is the inferno-collapse-perf command for that).

The profiler already uses inferno and can already generate flamegraphs. (: You just need to use the server subcommand to be able to access that functionality. (You can either access it through the GUI, or through the REST API.)

Yes, I saw them for leaked allocations but did not realize that I could change /data/…/export/flamegraph/flame.svg?lifetime=only_leaked to /data/…/export/flamegraph/flame.svg. So it's just a matter of having a link in the UI?

There is a link in the UI. (: When you browse through the allocations you can click in the upper right corner to access a menu with a link to a flamegraph. (I might replace that menu with a sidebar in the future so that it's more obvious.)

Ah :) Yes, similar to the leaked-allocation flamegraph link such a link could be displayed behind All allocations as well. Anyway, thanks for the reply.
