This the second part of a blog post on using the Grafana graphing tool to create an Oracle database performance dashboard for monitoring host and database performance in real time.

In the previous blog post I created a process to read key metrics from Oracle and insert them into a PostgreSQL database. This intermediate step was necessary as the free edition of Grafana does not include the connector to read directly from Oracle.

Once the metrics were loaded into a PostgreSQL table, a second process calculated deltas for those Oracle metrics that are cumulative. The results were then read by Grafana to show host performance and also report on the number of connected Swingbench users.

In this blog post I am going to expand on that and add IO metrics to track read and write IOPs and also throughput.

As before, all code is available from my GitHub repository.

In a previous blog post I explored how we can use Oracle’s rich V$ views to monitor CPU utilization on the host on which our database is running, as well as the IO generated by all nodes of the database.

Numbers are great, but it would be even better to see the loads represented graphically on a dashboard for an immediate read on how the database and the underlying infrastructure is handling the workload.

In this blog post I will use the Grafana visualization package to create a simple performance dashboard for our Oracle database.
