PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

• -E: will describe the underlaying queries of the \ commands (cool for learning!)
• -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

This is a short tutorial on setting up munin to monitor your Django website on ec2.

We're gonna be using Nginx instead of apache here because it's more lightweight and popular between Django developers.

Step by step tutorial

1. Install munin
