Oracle free tier - down time
reddit / selfhosted

I have actually had a positive experience (!) with hosting some
services on oracle free tier, very reliable over 2yrs now. But one of
my three instances occasionally has some down time recently -
including yesterday (no services on that server responding, couldn't
login via terminal).


Is there a way to confirm the down time - at the time and/or after the
fact - or look at service levels?


I want to check (seeing it's 1/3 instances, always same instance)
whether it really is downtime, or something unstable I did...

If it's an oracle problem you should see it somewhere on their panel
that there are issues in your AD, if all the instances are on the same
region and same AD, the fact that only one has issues is weird.

I would monitor the instance in detail. If you have the Oracle daemons
running you might want to look at the metrics that they collect in the
computing panel.

If you instead got rid of any monitoring from Oracle you can easily
spin Prometheus+node exporter+grafana to record and display key
computing metrics prior (or maybe even during) these down times.

Thanks.  I went through the dashboard and regular outages show up in
the metrics for the instance.  Each one is preceded by memory spike to
100%.  I've stopped the container I suspect might do that to see if
it's a fix.
