#Linux NFS I/O traffic including time, user, group, process name, pid, pathname, read bytes, write bytes, open, close, and file-descriptor data using only#bpftrace,#POSIX sh, and#awk -

#Linux#bpftrace on CentOS 7.7 (original repo used docker to build bpftrace and was not idempotent; my forked repo uses no docker and is idempotent) -
