The problem is that at some point it hangs. The only way to get it to work
again is to power it off and then restart it. I'd like to devise a log of
some sort that I can run from another machine that will give me some idea
of what was going on when it hung. I envision some kind of ping from my
main machine to
the troublesome one. I'm assuming I could use a script run by CRON (if
that's saying it right). Is there something more useful than just ping?
The good news is there are a lot of logging and monitoring tools. The bad
news is that if you don't have some idea of what you're looking for or what
tools give you what information, this can really complicate matters.
You say the machine is up 24/7. For what purpose? Mail server, web server,
dns cache, etc?
Right now it's my spare machine. It's available if something goes wacky
with my primary machine and I need to keep working. I don't recall the
last time that happened, so it's pretty rare. So, nothing in particular
is running, other than the usual OS stuff. It used to be the machine I
had in the living room with the HDMI port on the nVidia card connected
to the TV. I used to use it when we wanted to watch something together.
Right now I'm using the machine that used to be my spare machine. The
stuff we watch on it is two Zoom meetings a week, plus anything we both
want to look at on YouTube, or similar. So, not heavily used.
How often does it hang? Is there any kind of discernable pattern with an
app you're using, a background process that's running, etc?
Since it sits more or less idle for long periods, several days in
length, I don't know when it hangs. Right now, unless I think about
looking to see if it's still up, I won't know if it's hung or not.
If it's hanging pretty regularly with short intervals between each hang,
I'd maybe start with having HTOP or Conky running to watch processes and
resource usage.
There are a lot of nice syslog viewer apps that have filters you can
configure that may help expose historical patterns.
I find that anything that can help me see historical patterns or provide
context is not only helpful but usually necessary because otherwise you're
left with searching the forums of the great interwebs for some insight on
what is usually a very cryptic error message that's generally not useful to
the user.
Kinda hard to find a pattern in system not used often.
Thanks for the thoughts.
