NetApp Harvest collects performance, capacity, and hardware metrics from ONTAP systems, exports them to a time-series database such as Prometheus or InfluxDB, and includes Grafana dashboards for visualizing those metrics. NetApp Harvest is an open-source, enterprise metric collector developed and maintained by NetApp to extract in-depth operational telemetry from ONTAP clusters, StorageGRID, and associated storage infrastructure.
Harvest queries ONTAP management interfaces (via REST API or ZAPI) at high frequencies to pull comprehensive counters across CPU utilization, network interfaces, disk subsystems, aggregates, and volume-level latency/throughput. It formats and exports these collected metrics directly into modern time-series databases. While Prometheus acts as the time-series storage and query engine and Grafana provides the visual layer, Harvest is the specific NetApp-built collector tool that extracts the data from ONTAP. ONTAP System Manager and Active IQ Unified Manager utilize proprietary built-in web visualization consoles rather than Grafana-based metric displays.
