3.1 Aggregating Data

What

The FileWave dashboard can show raw device data, but aggregated data is what gives you the quick summary. Aggregation rolls many records into something easier to read, such as counts by version, model, or status.

When/Why

Use aggregation when you need the big picture instead of a long list. For example, if you are rolling Java from build 183 to build 196, a per-device report shows every record, but an aggregated view shows how many devices are still on each version. That makes rollout progress much easier to understand at a glance.

How

To get aggregated data into Grafana, create a Prometheus scrape job that summarizes the inventory-query data you care about. The next articles in this section walk through that process: define the Prometheus job, test the scrape, review the resulting metric in Explore, and then turn it into a panel.
