23.05.0

[cgrinds]

23.05.0 / 2023-05-03

📌 Highlights of this major release include:

• 💎 Seven new dashboards:

  • StorageGRID and ONTAP fabric pool
  • Health
  • S3 object storage
  • External service operations
  • Namespace
  • SMB
  • Workloads

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

  • Qtree dashboard includes topK qtrees by disk-used growth
  • StorageGRID Overview dashboard includes traffic classification panels
  • Network dashboard includes net routes
  • Average CPU utilization and CPU busy are included in the cDOT, Cluster, Node, and Metrocluster dashboards
  • SVM dashboard includes LIF counters and the NFS panels filter graphs by NFS version
  • Volume dashboard includes efficiency statistics
  • Aggregate dashboard includes the amount of free space
  • Compliance dashboard only reports on data SVMs

• 🔐 Harvest can fetch cluster credentials via a credential script. Thanks to Ed Wilts for raising.

• 🌾 Harvest includes new templates to collect:

  • IP routes. Thanks jfong for contributing!
  • QoS fixed and adaptive policy groups. Thanks @faguayot for raising!
  • Cloud targets and storage
  • Export rules
  • Namespaces
  • CIFS clients
  • LIF counters
  • Volume efficiency stats

• Harvest containers are published to GitHub's container registry in addition to DockerHub and cr.netapp.io.
  If you're using cr.netapp.io, we encourage you to switch to ghcr.io or DockerHub. In 2024, we will stop publishing to cr.netapp.io

• Harvest uses a distroless image as its base now - reducing the size of the container and reducing the attack surface

• Harvest collects 38 additional EMS events and alert rules in this release

• Harvest EMS alert rules were updated to include better label names and align their severity with Prometheus best practices. Thanks to @7840vz for contributing this feature!

• The bin/harvest doctor tool validates your custom.yaml template files, checking them for errors.

• 📕 Documentation additions

  • How to set up Harvest with Kubernetes
  • Harvest metadata metrics
  • Authenticating with ONTAP and StorageGRID clusters and auth precedence
  • Pollers include a prefer_zapi flag that tells Harvest to use the ZAPI API if the cluster supports it, otherwise allow Harvest to choose REST or ZAPI, whichever is appropriate to the ONTAP version. See rest-strategy for details.

• 🎩 Harvest makes it easy to run with both the ZAPI and REST collectors at the same time. Overlapping resources are deduplicated and only published to Prometheus once. This was the final piece in our journey to REST. See rest-strategy.md if you are interested in the details.

Announcements

IMPORTANT The volume_aggr_labels metric is being deprecated in the 23.05 release and will be removed in the 23.08 release of Harvest (#1966) volume_aggr_labels is redundant and the same labels are already available via volume_labels.

IMPORTANT To reduce image and download size, several tools were combined in 23.05. The following binaries are no longer included: bin/grafana, bin/rest, bin/zapi. Use bin/harvest grafana, bin/harvest rest, and bin/harvest zapi instead.

‼️ 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

• Harvest does not calculate power metrics for AFF A250 systems. This data is not available from ONTAP via ZAPI or REST.
  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.
