Rippled Server States

I learned that there are several states about rippled server
and i wonder which state means rippled server is running successfully and can be connected successfully

when i get full , validating , and proposing states, i would define rippled server can be connected and work well,but ‘tracking’ ? can it also run normally?

tracking The server is in agreement with the network

I find that servers rarely stay in the “tracking” state for long. You should expect a server that’s working well to remain in the “proposing” state (if validating) or “full” state (non-validators) without changing states.
