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

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 <N> --nostream runner2

Reading logs available even if the service was stopped - so it's useful to understand reasons of downtimes and so on

6. Stop a testnet

pm2 stop runner2

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
