To build a simple graph over time ( for example like an hour) it can’t because it does not store the past values. Postgres metrics include: Rows returne single stat for queries per second (QPS), buffers, and conflicts and deadlocks.

Upon building a new graph, the query editor will jumpstart the editor with a valid example query (if one exists). You can then leverage this example and edit it to fit your needs.

I want Grafana to read the Postgres SQL data to plot the graph. Can anybody share some links or information about how to do the export of data from postgres to Grafana.

In my previous blog, we talked about Enterprise monitoring solution by Postgres Enterprise Manager(PEM) and how to use performance diagnostics to discover queries which are consuming high IO. SQL DB database is the datasource of Grafana 3. MySQL and PostgreSQL as a backend database. Forked from influxDB plugin, this datasource frontend has been implemented.

Therefore, you can issue SQL queries in the same manner as in influxDB. Once the frontend and backend code is fully functional, we will push your branch to the grafana repo and work on extracting an abstraction for sql data sources. Does this sound like it could work for you?

Stored procedure support: Grafana supports SQL Server stored procedure calls, but the creators warn us about edge cases where it may not work.
