22.08.0 / 2022-08-19

🚀 Highlights of this major release include:

• 🎇 an ONTAP event management system (EMS) events collector with 64 events out-of-the-box

• Two new dashboards added in this release

  • Headroom dashboard
  • Quota dashboard

• We've made lots of improvements to the REST Perf collector. The REST Perf collector should be considered early-access as we continue to improve it. This feature requires ONTAP versions 9.11.1 and higher.

• New max plugin that creates new metrics from the maximum of existing metrics by label.

• New compute_metric plugin that creates new metrics by combining existing metrics with mathematical operations.

• 48 feature, 45 bug fixes, and 11 documentation commits this release

IMPORTANT ‼️ NetApp is moving their communities from Slack to NetApp's Discord with a plan to lock the Slack channel at the end of August. Please join us on Discord!

IMPORTANT ‼️ Prometheus version 2.26 or higher is required for the EMS Collector.

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 or from the Grafana UI.

Known Issues

Podman is unable to pull from NetApp's container registry cr.netapp.io. Until issue is resolved, Podman users can pull from a separate proxy like this podman pull netappdownloads.jfrog.io/oss-docker-harvest-production/harvest:latest.

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.

The Unix collector is unable to monitor pollers running in containers. See #249 for details.
