 ## Why does APerf exist?
 Performance issues in applications are investigated by recreating them locally and collecting data/metrics using monitoring tools like sysstat, perf, sysctl, ebpf, etc... or by running these tools remotely.

-The aim of APerf is to enable anyone to collect performance data in their enviornment while providing tools to analyze and visualize application performance. APerf will hopefully enable faster troubleshooting by analyzing and highlighting deviations in performance between two application environments automatically.
