Change Log

Releases

21.05.4 / 2021-07-22

This release introduces Qtree protocol collection, improved Docker and client authentication documentation, publishing to Docker Hub, and a new plugin that helps build richer dashboards, as well as a couple of important fixes for collector panics.

IMPORTANT RPM and Debian packages will be deprecated in the future, replaced with Docker and native binaries. See #330 for details and tell us what you think.

Known Issues

On RHEL and Debian, the example Unix collector does not work at the moment due to the harvest user lacking permissions to read the /proc filesystem. See #249 for details.

  • Harvest Grafana tool (optionally) adds a user-specified prefix to all Dashboard metrics during import. See harvest grafana --help #87

  • Harvest is taking its first steps to talk REST: query ONTAP, show Swagger API, model, and definitions #292

  • Tagged releases of Harvest are published to Docker Hub

  • Harvest honors Go's http(s) environment variable proxy information. See https://pkg.go.dev/net/http#ProxyFromEnvironment for details #252

  • New plugin value_to_num helps map labels to numeric values for Grafana dashboards. Current dashboards updated to use this plugin #319

  • harvest.yml supports YAML flow style. E.g. collectors: [Zapi] #260
