This is exactly how my network is setup. All devices log to my syslog server which I feed into a database with a self made python app, and Grafana goes from there. It’s been running nonstop for like 5 years without any problems, so I’d say your in the right path!

It’s also helped me catch things like:

• finding out android leaked IPs outside VPN tunnels on connect (prior to headlines claiming this)
• finding out nslookup on termux ignores the phone’s DNS settings and tries to use Google instead
• finding other devices that ignore my DNS server settings
• noticing that my work Mac will turn itself on in some weird silent passive mode in the middle of the night to try and send data to apple (sleep or powered off don’t matter) - caught this from the logs sent by my router
