> URL: https://issues.apache.org/jira/browse/HDDS-4984
> Project: Apache Ozone

> HDDS-1116 added the servlet for async profiler which outputs a flame graph in svg format.
> The async profiler (https://github.com/jvm-profiling-tools/async-profiler) 2.0 no longer supports svg. Instead, html only. Therefore, Ozone can't use the latest async profiler.
> File this patch to make a small change to output html format.
> Essentially, Ozone's async profiler servlet creates a process of "/path/to/profiler.sh -e cpu -d 10 -o svg -f /path/to/output.svg pid" We should make it "-o html -f /path/to/output.html"
