Variables

• litecoind_home: '/opt/litecoind' - directory for blockchain data
• litecoind_versoin: 'latest' - litecoin docker image tag
• litecoind_rpcuser: 'rpcuser' - user for RPC authorization
• litecoind_rpcpassword: 'rpcpassword' - password for RPC authorization
• litecoind_rpcport: 9322 - RPC port
• litecoin_network: 'mainnet' - LTC network (mainnet/testnet)
• ltc_user: 'ltc' - restricted user for monitoring script
• ltc_exporter_home: '/opt/ltc_exporter' - directory for ltc exporter script
• ltc_exporter_port: 8557 - port for ltc exporter script
• ltc_cryptoapis_key: longapikey - API key for CryptoAPIs.io services
• ltc_exporter_interval: 600 - how often (in seconds) need to fetch info about blocks

Prometheus exporter

This is very simple script, which provides following metrics:

# Some default Python metrics skipped

# HELP ltc_last_block Last block in our blockchain
# TYPE ltc_last_block gauge

# HELP ltc_last_etalon_block Last block in etalon blockchain
# TYPE ltc_last_etalon_block gauge

As etalon blockchain, we use Blockchain APIs from CryptoAPIs.io (the free plan is enough for that simple monitoring).
