DevConf.in 2018 is the second free annual community conference sponsored by Red Hat for Developers, System admins, DevOps engineers, Testers, Documentation writers and other contributors to open source technologies. It is a platform for the local FOSS community participants to come together and engage in the knowledge sharing through technical talks, workshops, panel discussions, hackathons and such activities.
Debugging kernel issues or performance blocker is hard and tedious if you have to go through the cycle of build -> install -> reboot and test, repeatedly till you make the correct diagnosis. It is time consuming and tiring and boring.
Enter SystemTap -> https://sourceware.org/systemtap/
SystemTap is your lens into the guts of the Linux kernel to see, in real time, what kernel is doing. It is a powerful tool which lets you fix probes points and observe kernel behavior at those specific points. In this session, we'll learn how it's done and have some fun along the way. :)
