Prosys OPC UA Forge Grafana Plugin

Rebuilt large parts of the plugin so that queries run through the Grafana server instead of the web browser. Because of this change, separate plugin packages are now provided for each supported operating system and processor architecture. The plugin now consists of 3 parts: An app plugin that contains the other 2 plugins, the datasource plugin and a control plugin (implemented as a panel plugin)

Added support for writing control values to nodes via the control plugin

Added support for Grafana alerting

Disabled caching for historical reads when aggregation is enabled

Fixed buggy data type detection for null data

Added logic to update the label of a query to match the display name of a node selected from the address space browser

Added automatic unit detection for queries based on the node’s EngineeringUnits property, with an option to override the detected unit manually

Added automatic minimum and maximum value detection for queries based on the node’s EURange property, with an option to override the detected values manually

Added an address space browser for selecting node ids in queries

Added aggregation options for historical reads

Internal reliability improvements (Including a bug fix for copying/importing dashboards from JSON)

Fixed concurrency conflicts for multiple queries targeting the same UA node by using a UUID as the cache key for each query instead of the UA node id

Made the cache size configurable

Fixed data pruning behavior for historical data fetching

Added third-party component information

Fixed a bug related to handling of null bounds that caused a flickering effect when fetching historical data

Fixed a bug that prevented individually switching on/off the constant value graphing feature, if multiple queries were added to the same graph

Added a feature that enables proper graphing of constant values and values that change infrequently

Added real-time data fetching

Updated the logo of the plugin in Grafana

Fixed a bug that caused certain UA nodes with number types to not be displayed

Improved the datasource connection test so that it takes into account the user’s API key

Removed the index range field from queries
