Monitoring your address

[wiseby]

Newbie here, can't post to relevant topic.
So I have some bitcoins.
I have a KEY -> ADDRESS pair.
I want to monitor my balance on a server.

Requirements:
 can run full node
 don't use third party services like blockchain.info
 don't import KEY on the server for obvious security reasons.
 don't use deterministic wallet

Armory does offer watch only wallets, but only for it's own type of determenistic wallets.
My own KEY -> ADDRESS is not an armory deterministic wallet. It is just a regular pair.

Any way to monitor my balance on a server?
