I am using kubectl-flame to run async-profiler on k8s pods.
When profiling a microservice that runs multiple replicas - I have a separate *.svg flamegraph for each pod.
QUESTION: Is there a way to merge those *.svg files into one graph?
How to merge *.svg files created by java async profiler?

Since version 2.0, released more than a year ago, async-profiler no longer generates
svgoutput. It now creates Flame Graphs on HTML 5 Canvas. Such graphs are smaller in size and a way more responsive comparing tosvg.As to merging, it is much easier with another format supported by async profiler - collapsed stacks. Use
-o collapsedprofiler option to dump output in that format. Then, to merge profiles incollapsedformat, just concatenate the corresponding output files.A flame graph can be constructed from
collapsedoutput with a converter included in async-profiler package. Here is how to do it:
