Solana Onchain monitoring

Run locally

The monitor requires a schema registry, a kafka instance and a zookeper. You can use the ./ops/monitoring/docker-compose.yml

The contracts needs to be deployed and the required accounts created. You can follow the gauntlet instructions in smartcontractkit/chainlink-solana.

You need to provide a description of the feeds. It can either be a file path (say /tmp/feeds.json) or an RDD url. An example of a compatible json encoded feeds configuration is:

[
  {
    "name": "sol/usd",
    "path": "sol-usd",
    "symbol": "$",
    "heartbeat": 1,
    "contract_type": "ocr2",
    "status": "live",

    "contract_address_base58": "2jVYiZgQ5disuAUMxrF1LkUyhZuqvRCrx1LfB555XUUv",
    "transmissions_account_base58": "2jVYiZgQ5disuAUMxrF1LkUyhZuqvRCrx1LfB555XUUv",
    "state_account_base58": "2jVYiZgQ5disuAUMxrF1LkUyhZuqvRCrx1LfB555XUUv",
  }
  {
    "name": "link/usd",
    "path": "link-usd",
    "symbol": "L",
    "heartbeat": 1,
    "contract_type": "ocr2",
    "status": "live",

    "contract_address_base58": "GUnMZPbhxkimy9ssXyPG8rVTPBPFzL24W4vFuxyEZm66",
    "transmissions_account_base58": "GUnMZPbhxkimy9ssXyPG8rVTPBPFzL24W4vFuxyEZm66",
    "state_account_base58": "GUnMZPbhxkimy9ssXyPG8rVTPBPFzL24W4vFuxyEZm66",
  }
]
