-------------------------------------
Summary: Async profiler 2.0 no longer supports svg output
Key: HDDS-4984
URL: https://issues.apache.org/jira/browse/HDDS-4984
Project: Apache Ozone
Issue Type: Improvement
Reporter: Wei-Chiu Chuang
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"
