BCC is a toolkit for creating efficient kernel tracing and manipulation programs, and includes several useful tools and examples. It makes use of extended BPF (Berkeley Packet Filters), formally known as eBPF, a new feature that was first added to Linux 3.15. Much of what BCC uses requires Linux 4.1 and above. Web11.2 biolatency. biolatency is a BCC and bpftrace tool to show disk IO statistics with latency as a histogram. The term device latency refers to the time from issuing a request to the device, to when it completes, including time spent queued in the operating system. We can use biolatency to check disk stats and monitor disk IO performance. Webbiolatency traces block device I/O (disk I/O), and records the distribution of I/O latency (time). This is printed as a histogram either on Ctrl-C, or after a given interval in seconds. … inbalance st neots
