# Useful Commands

This page collects the most useful commands for daily Monad node operations.

### Check binary version

```bash
monad-node --version
```

### Check service status

All at once:

```
systemctl status monad-bft monad-execution monad-rpc --no-pager -l
```

One by one:

```
systemctl status monad-bft
systemctl status monad-execution
systemctl status monad-rpc
```

***

### Follow logs

```
journalctl -u monad-bft -f
journalctl -u monad-execution -f
journalctl -u monad-rpc -f
```

***

### Check current block height

```
curl http://localhost:8080/ \
  -X POST \
  -H "Content-Type: application/json" \
  --data '{"method":"eth_blockNumber","params":[],"id":1,"jsonrpc":"2.0"}'
```

RPC becomes active after statesync is completed.

***

### Check TrieDB usage

```
monad-mpt --storage /dev/triedb
```

TrieDB status output includes used space, history depth, and compaction-related information. The docs note that TrieDB is the dedicated blockchain state device and that its storage behavior is central to node performance.
