Monitor/Watch running rsync process

rated 0 times [ 49] [ 0] / answers: 1 / hits: 69320 / 2 Years ago, fri, june 17, 2022, 5:03:04

I have an rsync job that has been added to a crontab and when it's running, I can only check that there's a rsync PID and confirm with htop that it's eating up n amount of CPU and RAM.

What I'd like to do is to monitor what files are actually being rsync'ed in realtime...when I want to. FYI I haven't passed any verbose option to the command nor have I added some logging. I really just want to check what's being rsync'ed on demand.

Any idea how I could achieve that?

You can do (in POSIX shells, including bash):

strace -e open,openat $(ps -o lwp= -LC rsync | sed 's/^/-p/')

Or in zsh:

strace -e open,openat -p${^$(ps -o lwp= -LC rsync)}

Or in fish

strace -e open,openat -p(ps -o lwp= -LC rsync)

Or in rc/es:

strace -e open,openat -p`{ps -o lwp= -LC rsync}

To see what it's doing, or

lsof -ad3-999 -c rsync

to see what files it currently has opened.
