Trace Profiling

What is Trace Profiling? #

We define Trace Profiling as a feature that can tell users what happened for every thread during a distributing trace span.

What does Trace Profiling do? #

• How all threads were executed is recorded and can be replayed.
• The exact thread which executed the trace span is highlighted.
• The logs printed by each thread are collected and correlated to the relative thread with its timestamp.
• The code execution flame graph is correlated to the time series where the CPU is busy.
• The network-related metrics are correlated to the time series where the network syscalls are executing.
• The file-related metrics are correlated to the time series where the file syscalls are executing.
