[SOLVED] watchdogd -- not on system and yet it's running!?

jowski · 04-20-2022, 04:22 PM

I just looked at the processes running on my system and this has me confused. I have a process for 'watchdogd' but there's no watchdogd executable that I can find. I'm running Slackware 15.0 and here's some outputs:

root@bathroom:/home/jim# ps aux|grep watchdogd
root 147 0.0 0.0 0 0 ? S Apr16 0:00 [watchdogd]
root 8051 0.0 0.0 3968 2300 pts/15 S+ 14:16 0:00 grep watchdogd

root@bathroom:/home/jim# which watchdog
which: no watchdog in (/usr/local/sbin:/usr/local/bin:/sbin:/usr/sbin:/bin:/usr/bin)

root@bathroom:/home/jim# man watchdog
No manual entry for watchdog

root@bathroom:/home/jim# uname -r
5.12.10

kernel is vmlinuz-huge-5.12.10

Any ideas would be appreciated.

Thanks,
Jim

It's a kernel-side thing. It does not exists in the user space (your system) so nothing to see there.

Code:

wdctl --help

You can find other things about it by searching the man pages.

Code:

man -k watchdog
man wdctl

Thanks guys. I appreciate the quick and informative responses. Looks like there's noting to worry about.

The one thing I forgot to mention is there's no 'dev/watchdog' and 'insmod watchdog' fails with "No such file or directory". I could use this for a server that likes to crash when I'm half way across the US so should I open a new thread or continue this one and mark it unsolved?

Thanks again,
Jim
