bpftrace is suited for this kind of analysis: decomposing metrics into distributions or per-event logs, and creating new metrics for visibility into blind spots. bpftrace uses BPF (Berkeley Packet Filter), an in-kernel execution engine that processes a virtual instruction set. 6 * 7 * Copyright 2018 Netflix, Inc.

But do you know how Lighthouse calculates performance metrics like First Contentful Paint (FCP), Total Blocking Time (TBT), and Cumulative Layout Shift (CLS)? Still, there’s nothing in there to tell us about the data Lighthouse is using to evaluate metrics. But it comes with caveats. So why use lab data at all?

As HammerDB supports graphical metrics for Oracle, this provides the best illustration however the concepts apply in general terms to all databases. The first example shows a data load, the second a TPC-C based workload with 5 virtual users and the 2nd example with 10 virtual users. Oracle Log File Sync. Checkpoint not complete.
