How to check whether your node is healthy?

[ericlee42]

Install curl and jq first, and run following command to check if your node is healthy

$ curl -s 'http://localhost:8080/verifier/get/true/1088'  | jq '.verify.index'
1139855

You will get a number, it's current height of your node, and ensure that it is not zero and strictly increasing.

Run following command to check your node is synced

$ curl 'http://localhost:8080/verifier/get/true/1088' | jq '.batch.l1TransactionHash'
"0xef898dfc868d7936bc828513278192305883042c1038e28af3785f9a9770d25a"

You will get a transaction hash, it's the latest L1 batch transaction hash.

Open https://etherscan.io/address/0xf209815e595cdf3ed0aaf9665b1772e608ab9380

If the first transaction on the page is equal with you got, your node is synced.

What if you get an older TXH hash? Should the docker containers be restarted?
