Demonstrations of opensnoop, the Linux bpftrace/eBPF version. opensnoop traces the open() syscall system-wide, and prints various details. Example output: # ./opensnoop.bt Attaching 3 probes...

Also, the snmpd process opened various /proc and /sys files (reading metrics). was starting up: a new process). opensnoop can be useful for discovering configuration and log files, if used during application startup. There is another version of this tool in bcc: https://github.com/iovisor/bcc The bcc version provides command line options to customize the output.
