 `prometheus_enabled`|[Prometheus](https://prometheus.io) is a time series database. It holds all the data we're going to talk about.

-`prometheus_postgres_exporter_enabled`|[Postgres Exporter](#enabling-metrics-and-graphs-for-postgres-optional) is an addon of sorts to expose Postgres database metrics to Prometheus.
 `matrix_prometheus_nginxlog_exporter_enabled`|[nginx Log Exporter](configuring-playbook-prometheus-nginxlog.md) is an addon of sorts to expose nginx logs to Prometheus.
 
 **Note**: the retention policy of Prometheus metrics is [15 days by default](https://prometheus.io/docs/prometheus/latest/storage/#operational-aspects). Older data gets deleted automatically.
