It is a simple NEAR Lake indexer that just prints the block heights and exposes some Prometheus-friendly metrics:
- latest indexed block height
- number of blocks indexed
It is supposed to be used for healthcheck and check that the data we've reindexed to the AWS S3 buckets is consistent and doesn't have any gaps.
And also it can send alert notifications via TelegramBot (optional) if blocks per second rate drop to zero.
Don't forget you need to have ~/.aws/credentials with your AWS credentials
