<!-- title: "PostgreSQL monitoring with Netdata" custom_edit_url: https://github.com/netdata/netdata/edit/master/collectors/python.d.plugin/postgres/README.md sidebar_label: "PostgreSQL" --> # PostgreSQL monitoring with Netdata Collects database health and performance metrics. ## Requirements - `python-psycopg2` package. You have to install it manually. Following charts are drawn: 1. **Database size** MB - size 2. **Current Backend Processes** processes - active 3. **Current Backend Processe Usage** percentage - used - available 4. **Write-Ahead Logging Statistics** files/s - total - ready - done 5. **Checkpoints** writes/s - scheduled - requested 6. **Current connections to db** count - connections 7. **Tuples returned from db** tuples/s - sequential - bitmap 8. **Tuple reads from db** reads/s - disk - cache 9. **Transactions on db** transactions/s - committed - rolled back 10. **Tuples written to db** writes/s - inserted - updated - deleted - conflicts 11. **Locks on db** count per type - locks ## Configuration Edit the `python.d/postgres.conf` configuration file using `edit-config` from the your agent's [config directory](/docs/step-by-step/step-04.md#find-your-netdataconf-file), which is typically at `/etc/netdata`. ```bash cd /etc/netdata # Replace this path with your Netdata config directory, if different sudo ./edit-config python.d/postgres.conf ``` When no configuration file is found, the module tries to connect to TCP/IP socket: `localhost:5432`. ```yaml socket: name : 'socket' user : 'postgres' database : 'postgres' tcp: name : 'tcp' user : 'postgres' database : 'postgres' host : 'localhost' port : 5432 ``` --- [](<>)
