Hi,
If I want to log loss of connections to my router, what's a good way of
going about it?
Adding a script in "/etc/NetworkManager/dispatcher.d"?
Would that handle cases of loss of "internet connection" when it's not
a loss of the physical link between the PC and network switch?
ISP -- Router -- ethernet switch --> everything on my LAN
Frequently things on my LAN (cabled) would stop working, some with
error messages about "loss of internet" (e.g. firefox) others don't
give error messages (e.g. internet media devices, like a bluray player
with a YouTube app).
I'm fairly certain it's a bad router. The ethernet switch is brand new
and bought after the problems began. Logging into the router (and
doing nothing more than log into it) would usually bring things back to
life.
When I'm using devices, it's fairly obvious to me that it's gone for a
nap. I'm wondering how often things are going bad when I didn't
notice.
has many suggestions.
There are lots of potential failure modes, so you may be better off
with system monitoring tools that do more than pings.
packages, but with an unfixed bug (https://github.com/nagios-plugins/nagios-plugins/issues/647)
reported for RHEL 8 and also present in Fedora 36 in parsing ping responses.
Another tool is Performance Copilot, which I have also used in the past. There
are Fedora packages.
I use pakedge gear, so have OvrC, which can be configured to notify me when a
system stops responding to pings. There is https://github.com/ovrc/ovrc but
I have not tried to use it.
