This is a utility script for devs analyzing the performance profile contained in feedback logs. It can be used to extract the perf-data element from a feedback logs archive and save the extracted data to a file ready for analysis using pprof.
To extract the perf-data element from a system logs archive system_logs.zip and save to /tmp/perf-data.proto:
perf_data_extract.py system_logs.zip /tmp/perf-data.proto
To show the help message, set the -h flag:
perf_data_extract.py -h
