Bitcoin Stats Endpoint

[mayankchhabra]

@nolim1t can you do a bitcoind stats endpoint?

GET /api/v1/bitcoind/info/stats

Returns:

{
    peers: <number of connected peers>
    mempool: <size of amempool in bytes>
    hashrate: <network hashes per second>
    blockchainSize: <the estimated size of the block and undo files on disk>
}

---

We require it to display these stats on the dashboard:

@mayankchhabra - can you combine multiple calls together?

If so, this is already mostly implemented in master branch right now.

So all it would need is adding a few more endpoints

[mayankchhabra]

That's possible, but I would recommend against it... there's simply too much of polling happening already 🤢

[nolim1t]

This should be available soon (mempool info)

{"loaded":true,"size":2654,"bytes":920559,"usage":4068320,"maxmempool":512000000,"mempoolminfee":0.00001,"minrelaytxfee":0.00001}

[mayankchhabra]

Great, we just need the "usage":4068320 key-value pair

Im adding stuff to the sync endpoint because stuff exists. Maybe I should add mempool info there too?

[mayankchhabra]

To the sync endpoint? I don't think it's a good idea. Sync should only have the % sync value, tip, and the block header to ensure separation of concerns.

Either a separate endpoint /mempool or a combined, like /stats, should do.

[nolim1t]

the sync endpoint is calling the same RPC calls so that get the same information so they will get called anyway

[nolim1t]

block size and sync percentage are in the same call

[nolim1t]

However I will keep mempool separate because thats a different call

[nolim1t]

/v1/bitcoind/info/sync as of developmental branch

{
  "percent": "1.0000",
  "currentBlock": 627729,
  "headerCount": 627729,
  "difficulty": 15958652328578.42,
  "size": 311144972067
}

[nolim1t]

/v1/bitcoind/info/connections already exposes peers but I can expose the entire raw amount too

[mayankchhabra]

/v1/bitcoind/info/connections is ok as is

[nolim1t]

Also have a /stats endpoint for everything if you prefer one call.. wasn't so bad to add in
