Integrating OCI with Grafana

There is a practical reality in most operations teams that no amount of native tooling overcomes: people will only reliably look at one place. If the team lives in Grafana all day, watching their existing systems, then a separate OCI console, however good, becomes the place they forget to check. The metrics might be excellent, the dashboards well built, but if they are somewhere the team does not already have open, they go unwatched until an incident forces the issue. This is why integrating OCI into an existing Grafana setup is so often worth the effort. It is not that OCI lacks visualisation. It is that consolidating onto the one pane of glass the team already trusts is worth more than the best dashboard nobody opens.

How the integration works

Grafana connects to data through plugins called data sources, and OCI provides a data source plugin that lets Grafana read the metrics the OCI Monitoring service collects. Once the plugin is installed and configured, OCI metrics appear in Grafana the same way any other data source does, available to chart on dashboards, query, and alert on. The metrics themselves are the ones described in the monitoring service explainer, the compute, database, networking, and load balancer signals that OCI gathers. The plugin does not move or copy the data, it queries OCI when a dashboard is viewed, so the figures are current and you are not maintaining a second store of metrics. This keeps the integration light, a query path rather than a data pipeline.

Native dashboards against Grafana

The choice between OCI native dashboards and Grafana is not really about features, it is about where your team works. The table sets out the trade.

If OCI is your entire world, the native dashboards are the simpler path, ready immediately with full coverage and nothing to maintain. If OCI is one system among several, and especially if you run across more than one cloud, Grafana wins because it puts OCI next to everything else, and a single view of the whole estate beats a per system view every time. The principles of building a dashboard that people actually read, covered in building OCI dashboards, apply equally whichever tool you choose.

Authentication and access

For Grafana to read OCI metrics, it needs permission to do so, and how you grant that permission depends on where Grafana runs. If Grafana runs inside OCI on a compute instance, the cleanest approach uses an instance principal, where the instance itself is granted the right to read metrics and no credentials are stored. If Grafana runs outside OCI, it authenticates with API credentials configured in the plugin, which must be created with the minimum permission needed, read access to metrics and nothing more. The principle in both cases is least privilege. Grafana needs to read metrics, so grant it exactly that and no broader access, because a visualisation tool should never hold more permission than its job requires. Getting this right keeps the integration secure as well as useful.

Building a unified view

The payoff of the integration is the dashboard that shows the whole estate at once. A single Grafana dashboard can display the OCI database health beside the application metrics from another platform beside the network signals from a third, so an engineer sees the entire system in one place and can correlate across it. This matters most when a problem spans systems, when an application running outside OCI is slow because of an OCI database it depends on, and only a unified view shows both ends of that relationship together. Building these cross system dashboards is where Grafana earns its place, and it pairs naturally with consolidating logs in the same spirit, a theme in centralized logging architecture, so that both metrics and logs converge on one place.

The order below gets a working, secure integration without overreaching.

One pane of glass

The argument for integrating OCI with Grafana comes down to human behaviour more than technology. Teams watch the place they already have open, and putting OCI there means OCI gets watched. The integration is light, a query path rather than a copy of the data, and once it is in place OCI takes its seat alongside every other system the team operates, visible in the same dashboards and subject to the same alerting. For a team running OCI as one part of a larger estate, this consolidation is usually the right call. It sits within the broader observability practice of the complete monitoring and observability guide, alongside the metric foundation of the monitoring service and the logging service. When you want OCI integrated cleanly into the tools your team already uses, our OCI monitoring and observability practice sets up the integration and rebuilds the dashboards that matter.
