Oracle Continues Building DTrace For Linux Atop BPF

Phoronix - Fri, 10/30/2020 - 18:01
More than a decade ago Linux users tended to be envious of Sun Microsystems' Solaris for ZFS and DTrace as the two most interesting technical selling points of the platform. In that time OpenZFS is now extremely vibrant for offering ZFS on BSD and Linux systems while DTrace is barely brought up these days.
