# Netrunner and PM2
## Using PM2 for production management
PM2 allows you to run services in the background, monitor server resource usage, write logs, and more.

**PM2 is the recommended way to run and maintain a node (regular and validator) for Klyntar**
{% endhint %}
To run & work with a testnet you can use these simple commands:
## 1. Start a testnet in a single command:
```
pm2 start runner2.js
```
## 2. Check the active background services
You will see the following
## 3. Enter monitoring dashboard
```
pm2 monit runner2
```
## 4. Read the logs stream
```
pm2 logs runner2
```
## 5. Read last N lines of logs from stdout / stderr streams (`nostream` mode)
```
pm2 logs --lines --nostream runner2
```
{% hint style="info" %}
#### Reading logs available even if the service was stopped - so it's useful to understand reasons of downtimes and so on
{% endhint %}
## 6. Stop a testnet
```
pm2 stop runner2
```
{% hint style="info" %}
#### When you stop the testnet and then run it again - the progress will be dropped and testnet will start from height 0 and epoch 0
