📌 Highlights of this major release include:

⭐ New Features

• 🏅 Harvest now monitors Arista switches — a new BETA AristaRest collector gathers environment, interface, LLDP, optic, and version metrics from Arista EOS switches, along with a new Arista: Switch dashboard and setup documentation.

• 🏅 Expanded E-Series support — new pool, interface, workload, and application object collection; SSD cache support for older E-Series (SANtricity) versions; a new rawCapacity drive counter; collector-level filtering; firmware version support; and controller IP addresses collection.

• 🏅 Five new dashboards:

  • Arista: Switch
  • E-Series: Pool
  • E-Series: Interface
  • E-Series: Workload
  • E-Series: Application

• 💎 Dashboard enhancements — several existing dashboards include new panels:

  • ONTAP:Aggregate: Top Aggregates by Space Used % panel
  • ONTAP:Disk: pool and path count
  • ONTAP:Network / Node: port health status
  • ONTAP:Workload: .* support in the Workload variable
  • E-Series:Drive: raw capacity

• 🌾 New templates to collect:

  • Arista EOS: environment, interface, LLDP, optic, and version
  • E-Series: pool, SSD cache, and workload, plus performance templates for application, interface, SSD cache, and workload
  • ONTAP: volume efficiency
  • StorageGRID: new storagegrid_labels metric

• MCP enhancements:

Announcements

💡 IMPORTANT After upgrade, don't forget to re-import your dashboards, so you get all the new enhancements and fixes. You can import them via the 'bin/harvest grafana import' CLI, from the Grafana UI, or from the 'Maintenance > Reset Harvest Dashboards' button in NAbox3. For NAbox4, this step is not needed.

💡 Arista collector and dashboards are beta as we collect more feedback.
