I've been using a .rsync-filter file for something like what you mean for ages for my homedirs backups. It's a bit tricky probably to make it right the first time but once it's there it just works.
That's why I'm still using munin, even for kubernetes clusters, even after 20 years in the business, if I should need a plugin that I wrote back then it would still work!
And I can monitor a whole k8s cluster (around 70 nodes) using 100MB of mem and 3G for storage (up to 1 year).
It's just one click and hopefully a password away. I use "personal CAs" everywhere, if you share the p12 file via a webserver it's installed by the browser when you click on the link, and share the password over phone or another medium.
If it needs constant monitoring it's a potential problem... And at some point it will happen... We know that from ages of software development, if it can fail, it will fail at some point.
Thanks for your feedback, and I pretty understand what you mean, I've worked with some DBA know as the "million dollars error guy". But I think that's a second step, and anyway we were maintaining the servers where those dbs were running... So we deserve some trust maybe?
Hi, my apologies if it's a bit off topic, but I wonder if you have any advise or can point me in some direction on the way to becoming a DBA, or something similar enough? I've been working as and old school sysadmin for the last 17 years and counting. Even if I can do nowadays devops stuff, I always liked the DBA work, based on my experience as sysadmin for DB servers (mysql, oracle, and friends...), and I'm considering moving my career in that direction. So is there any "DBA certification" for which I could take a course and all that? Thanks!!
