Linux System Performance/Observability Tools Linux Systems Performance/Observability (BPF (bpfcc-tools), BCC Tools Assuming you have Linux Server in place and have the required BPF aka BCC related packages installed on the system(s) for the required Linux distribution. BPF(eBPF) aka BCC Tools (bpfcc-tools) : BPF, which originally stood for Berkley Packet Filter is the dynamic tracing tools for Linux Systems. BPF initially used for the speeding up for the tcpdump expressions and since then it has been know as the extended Berkley packet Filter (eBPF). Its new uses are Tracing Tools where it provides programmability for the BPF Compiler Collection (BCC) and bpftrace front ends . Example: execsnoop, biosnoop etc is a BCC Tool. When facing production performance crisis these such list of tools comes handy to trace and fix the issue. However, it requires certain KERNEL level config options to be enabled such as CONFIG_FTRACE, CONFIG_BPF. Profiling tools typically re...
