### Automatic Restarts and Monitoring <a href="#automatic-restarts-and-monitoring" id="automatic-restarts-and-monitoring"></a>

{% hint style="info" %}
to get koisan-chian node running as a background service on Ubuntu can use supervisor for monitoring
{% endhint %}

* Install supervisor on ubuntu

```
$ apt-get install supervisor
```

Finally we have to add a configuration file to supervisor to let it know that it should run geth, Create /etc/supervisor/conf.d/geth.conf and fill it with:

```
[program:geth]
command=/path/to/koisan-chain/build/bin/geth --fast --http --http.addr 127.0.0.1 --http.port 8545 --http.corsdomain * --http.api admin,db,eth,debug,miner,net,shh,txpool,personal,web3
autostart=true  
autorestart=true  
stderr_logfile=/var/log/supervisor/koisan.err.log  
stdout_logfile=/var/log/supervisor/koisan.out.log  
```

* Now just restart supervisor to startup geth:

```
$ supervisorctl reload  
```

Boom! You can now attach a console to your running geth instance by typing geth attach. You can then query it using the standard [commands](https://geth.ethereum.org/docs/interface/javascript-console).
