  • Harvest provides an option to limit concurrent ONTAP HTTP connections. Thanks @songlin-rgb for raising.

  • Harvest MCP enhancement:

    • Harvest MCP includes metric unit and type information for performance metrics. Thanks @gautcher for reporting.
    • Harvest adds health endpoint in harvest mcp. Thanks @yann for reporting.
    • Harvest supports prometheus/victoriametrics endpoint retry in mcp-server. Thanks @yann for reporting.

Announcements

💡 IMPORTANT After upgrading, don't forget to re-import your dashboards to 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.

💡 E-Series collector and dashboards are beta as we collect more feedback.
