I’m monitoring my system with a RPi and keeping the data with MySql. How often should I query my system? Once a minute? Only when there’s a change from the last query? Thoughts?

How often to query system for database?
I read multiple (~20) holding registers every 10 seconds on my system.
On my CerboGX, the modbus service usues 3% CPU on average and the overall doesn't go above 20% CPU on average.
