![]() ![]() In Ubuntu 16.04 need to upgrade or change kernel parameters, just run the following commands to add its source key in the repository and then run system update. CONFIG_BPF=yĬONFIG_BPF_EVENTS=y Installing BCC (BPF Compiler Collection) on Ubuntu 16: If your kernel version is other than the mentioned version then it should have been compiled with the following flags set in the '/boot/config-4.4.0-21-generic'. In order to install BCC, a Linux kernel version 4.1 or newer is required. These capabilities gives the information with the lowest possible overhead cost. eBPF enhances Linux tracing, allowing mini programs to be executed on tracing events and lets you tag events with custom timestamps, store histograms, filter events and emit summarized info to user-level. It is suited for many tasks, including performance analysis and network traffic control. ![]() BCC makes eBPF programs easier to write, with kernel instrumentation in C and a front-end in Python. BPF guarantees that the programs loaded into the kernel cannot crash, and cannot run forever, but yet BPF is general purpose enough to perform many arbitrary types of computation. The BPF Compiler Collection (BCC) is a toolkit for building kernel tracing tools that leverage the functionality provided by the Linux extended Berkeley Packet Filters (BPF). ![]() Greetings, BCC is now available for Ubuntu and in this article we will be showing you its extended command line use to trace Linux systems for performance monitoring. ![]()
