23.08.0

23.08.0 / 2023-08-21 Release

📌 Highlights of this major release include:

• Harvest Security dashboard highlights compliance using NetApp's Security hardening guide for ONTAP

• Harvest's credential script supports ONTAP daily credential rotation. Thanks to @mamoep for raising.

• 🎩 Harvest makes it easy to run with both the ZAPI and REST collectors at the same time. Overlapping resources are deduplicated and only exported once. Harvest will automatically upgrade ZAPI conversations to REST when ZAPIs are suspended or disabled.

• 💎 Updated workload dashboard now includes Service Center, Latency Breakdown, and 50 panels

• 💎 Cluster dashboard updated to work with FSx. Some panels are blank because FSx does not have that data.

• 📣 The Harvest team published a couple of screencasts about:

  • Why Harvest
  • Harvest Quick Start: Docker Compose

• ⭐ Several of the existing dashboards include new panels in this release:

  • Aggregate dashboard includes busy volume panels
  • SVM dashboard includes per NFS latency heatmaps. Thanks to @rbrownATnetapp for raising.
  • Volume dashboard includes top resources by other IOPs panel and junction paths. Thanks to @tsohst for raising.

• All Harvest dashboard tables include column filters

• Harvest dashboards use color to highlight latency and busy threshold breaches

• Harvest's Prometheus exporter supports TLS

• 🌾 Harvest includes new templates to collect:

  • Iwarp metrics
  • FCVI metrics
  • Per volume NFS metrics
  • Volume clone metrics
  • QoS workload policy metrics
  • NVME/TCP and NVME/RoCE metrics
  • Flashpool metrics are included in RestPerf. Thanks to @lobster1860 for raising

• 📕 Documentation additions

  • Move more documentation from GitHub to Harvest documentation site
  • Clarify how to tell Harvest to continue using the ZAPI protocol
  • Clarify generic vs custom plugins. Thanks to GregS for raising
  • Clarify which version of Go is required to build Harvest. Thanks to MikeK for raising
  • Clarify how to prepare ONTAP cDOT clusters for Harvest data collection
  • EMS documentation should point to Harvest documentation site. Thanks to @cwaltham for raising
  • Clarify how to gather log files on all platforms
  • Explain how to use the --labels option of bin/harvest grafana. Thanks to @slater0013 for raising
  • Describe how to run docker compose generate command without required Harvest binaries

• The Harvest doctor command validates collector names listed in your harvest.yml file

• An earlier version of Harvest collected cloud store information via REST. This release adds the same for ZAPI

• When ONTAP resources are missing, Harvest tries to collect them every hour. Earlier versions of Harvest waited 24 hours before retrying, which often caused metrics to be missing after a cluster upgrade. Thanks to @Falcon667 for raising

• Earlier versions of Harvest created world writable auto-support files. These files are now only read/writeable by the current user. Thanks to Bunnygirl for raising

• bin/harvest import should work with Grafana 10. Thanks to @wooyoungAhn for raising

Announcements

‼️ IMPORTANT 23.08 fixes a REST collector bug that caused partial data collection when ONTAP paginated results. See #2109 for details.

‼️ IMPORTANT Release 23.08 disables the NetConnections and NFSClients templates by default. You can enable them if needed. These templates were disabled because several customers reported that these templates created millions of metrics. None of these metrics are used in Harvest dashboards.

‼️ IMPORTANT Release 23.08 changes how Harvest monitors workloads. For detailed information, please refer to the discussion #2265.

💡 The Compliance dashboard was removed after its panels were moved to the Security dashboard.

👀 Ambient temperature metric may experience an increase due to issue #2259

‼️ IMPORTANT NetApp moved their communities from Slack to Discord, please join us there!

‼️ IMPORTANT If using Docker Compose and you want to keep your historical Prometheus data, please
read how to migrate your Prometheus volume

💡 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 NAbox.

Known Issues

• Some AFF A250 systems do not report power metrics. See ONTAP bug 1511476 for more details.

• ONTAP does not include REST metrics for offbox_vscan_server and offbox_vscan until ONTAP 9.13.1. See ONTAP bug
  1473892 for more details.

IMPORTANT 7-mode filers that are not on the latest release of ONTAP may experience TLS connection issues with errors like tls: server selected unsupported protocol version 301 This is caused by a change in Go 1.18. The default for TLS client connections was changed to TLS 1.2 in Go 1.18. Please upgrade your 7-mode filers (recommended) or set tls_min_version: tls10 in your harvest.yml poller section. See #1007 for more details.
