# node data directory with configs and keys
admin.datadir
# check if node is connected
net.listening
# show synchronization status
eth.syncing
# node status (difficulty should be equal to current block height)
admin.nodeInfo
# show synchronization percentage
eth.syncing.currentBlock * 100 / eth.syncing.highestBlock
# list of all connected peers (short list)
admin.peers.forEach(function(value){console.log(value.network.remoteAddress+"\t"+value.name)})
# list of all connected peers (long list)
admin.peers
# show connected peer count
net.peerCount
