- Enable the configuration item in the taosAdapter configuration file (default location /etc/taos/taosadapter.toml)

```
...
[statsd]
enable = true
port = 6044
db = "statsd"
user = "root"
password = "taosdata"
worker = 10
gatherInterval = "5s"

maxTCPConnections = 250
tcpKeepAlive = false
allowPendingMessages = 50000
deleteCounters = true

```

The default database name written by taosAdapter is `statsd`. To specify a different name, you can also modify the taosAdapter configuration file db entry. user and password fill in the actual TDengine configuration values. After changing the configuration file, you need to restart the taosAdapter.

### Configuring StatsD

To use StatsD, you need to download its [source code](https://github.com/statsd/statsd). Please refer to the example file `exampleConfig.js` in the root directory of the source download to modify the configuration file. In <taosAdpater's host\>, please fill in the domain name or IP address of the server running taosAdapter, and <port for StatsD\>, please fill in the port where taosAdapter receives StatsD data (default is 6044).

```
backends section add ". /backends/repeater"
Add { host:'<taosAdapter's host>', port: <port for StatsD>} to repeater section
```

Example configuration file.

```
{
port: 8125
, backends: [". /backends/repeater"]
, repeater: [{ host: '127.0.0.1', port: 6044}]
}
```

node stats.js config.js &
```
