Cardano's Shelley Testnet block generation

Hello, my node 1.5.1 seems to work fine, except topologyUpdater which is returning ‘blockNo seems to be out of sync’ so i manually add a list of peers in my topology file.
But i still have no block minted after more than 2-3 days, does it exists a script that checks health of a node ? How can i know if my node is working as expected ? Thanks.
