+# swarmstack/postgresql-exporter
+
+Docker compose file for postgres-exporter, Prometheus configuration example, and Grafana Dashboard for PostgreSQL servers
+
+
+## USAGE
+
+```
+docker stack deploy -c docker-compose.yml postgresql-exporters
+```
+
+[swarmstack](https://github.com/swarmstack/swarmstack) users should use docker-compose-swarmstack.yml above instead.
+
+---
+
+In the prometheus/ directory in this repo, you'll find example Prometheus configurations to scrape the exporters once per 5 minutes as to not induce extra load on your servers. If your PG servers aren't heavily loaded, you can scrape them at whatever interval you like.
+
+In the grafana/ directory you'll find a Grafana 6.0+ dashboard that uses information from the postgres-exporter plus netdata to give you a full view of your PostgreSQL hosts.
