Make it executable, then run it as shown: $ chmod +x bcc-install.sh Note: update PREFIX value to the latest date, and also browse the files in the PREFIX url provided to get the actual REL value, substitute them in the shell script. Īs an example, write a small shell script “ bcc-install.sh” with the content below. $ echo 'deb xenial-nightly main' | sudo tee /etc/apt//iovisor.listīegin by installing a 4.3+ Linux kernel, from. No need of kernel upgrade or compile it from source.

Only the nightly packages are created for Ubuntu 16.04, but the installation instructions are very straightforward. To check your kernel flags, view the file /proc/config.gz or run the commands as in the examples below: ~ $ grep CONFIG_BPF= /boot/config-`uname -r`ĬONFIG_BPF= y ~ $ grep CONFIG_BPF_SYSCALL= /boot/config-`uname -r`ĬONFIG_BPF_SYSCALL= y ~ $ grep CONFIG_NET_CLS_BPF= /boot/config-`uname -r`ĬONFIG_NET_CLS_BPF= m ~ $ grep CONFIG_NET_ACT_BPF= /boot/config-`uname -r`ĬONFIG_NET_ACT_BPF= m ~ $ grep CONFIG_BPF_JIT= /boot/config-`uname -r`ĬONFIG_BPF_JIT= y ~ $ grep CONFIG_HAVE_BPF_JIT= /boot/config-`uname -r`ĬONFIG_HAVE_BPF_JIT= y ~ $ grep CONFIG_BPF_EVENTS= /boot/config-`uname -r`Īfter verifying kernel flags, it’s time to install BCC tools in Linux systems. Remember that BCC uses features added in Linux kernel version 4.1 or above, and as a requirement, the kernel should have been compiled with the flags set below: CONFIG_BPF= y CONFIG_BPF_SYSCALL= yĬONFIG_NET_ACT_BPF= m CONFIG_BPF_JIT= y CONFIG_HAVE_BPF_JIT= y Additionally, it supports multiple tasks such as performance analysis, monitoring, network traffic control plus lots more. Suggested Read: 20 Command Line Tools to Monitor Linux Performanceīest suited for advanced Linux users, BCC makes it easy to write BPF programs using kernel instrumentation in C, and front-ends in Python and lua. Comprises of several performance analysis tools with example files and man pages.Enables observation of software execution.Requires no 3rd party kernel module, since all the tools work based on BPF which is built into the kernel and BCC uses features added in Linux 4.x series.Practically, most of the components used by BCC require Linux 4.1 or above, and its noteworthy features include:

BCC/BPF – Dynamic Tracing Tools for Linux Performance Monitoring It utilizes extended BPF ( Berkeley Packet Filters), initially known as eBPF which was one of the new features in Linux 3.15. BCC ( BPF Compiler Collection) is a powerful set of appropriate tools and example files for creating resourceful kernel tracing and manipulation programs.
