Improved compression. Note Widgets and YAML Template Files

Dashboard Note Widgets can include descriptions and can contain template expressions and links to external systems using the current parameter and time values

We are also introducing a new YAML file format for dashboard templates. The new format is much human-readable. It is the first step to being able to persist all entities (parsers, queries, alerts) as files.

Support for the now deprecated dashboard file import API and JSON format will continue, but expect it to be removed in a later release.

Bug Fixes

  • Configuration

    • COMPRESSION_TYPE=high turns on a stronger compression when segments get merged. This results in better compression, at the expense of having slightly lower compression for the very recent events. The improvement is typically 2-3 times better compression for the merged segments.

    • COMPRESSION_TYPE=extreme uses the stronger compression also in the digest part, even though it is not as effective there due to the gain from having a larger file after the merge.

  • Functions

    • New function start() and function end() functions provides the time range being queried as fields.

    • New function urlEncode() and function urlDecode() functions allow for encoding or decoding the value of a field for use in urls.

    • The function parseJson() now accepts an exclude and include parameter. Use this to specify which fields should not be included.

  • Other

    • New function copyEvent() function allows duplicating an event into another datasource while ingesting. Use case to make the two events differ.

    • COMPRESSION_TYPE=fast (Default!) corresponds to versions before 1.6.x

    • Styling of the dashboard "Labels" dropdown has been fixed.

    • Introducing a new YAML dashboard file format.

    • Pending parameter edits toggle, so that parameter changes are not immediately applied if the user desires not to.

    • Added GraphQL fields for shared dashboards.

    • Renaming a repository is now possible in settings.

    • The function sort() query function now ignores case when sorting strings.

    • The sizes of the compressed files and the associated hash-filter files are tracked separately for the merged part, allowing you to see in the UI how well the long-term compression works as part of the total set.

    • Removed internal REST API for shared dashboards.

    • Added Note Widget support for dashboards.

    • Changing Dashboard labels will no longer trigger a "Dashboard was modified remotely" notification.

    • Note! Rolling back to v1.5.x is supported only for COMPRESSION_TYPE=fast which is the default in this release. The default is expected to change to "high" later on. The new compression types "high" and "extreme" are considered BETA release.

    • This update does not support rolling updates. Stop all Humio nodes. Then start them on the new version.

    • Added cluster information pages for the Zookeeper & Kafka Cluster used by Humio. Both are available under Administration.

    • Changed GraphQL fields for dashboard widgets.

    • Drawer heights were not being persisted between browser sessions.
