  • Advanced filtering of events now also supports aggregates.
  • Variables created with an asset-query can now return externalId and name as value in addition to id. This is useful when using a variable inside FDM graphQl query.

2.6.0 - August 4th, 2022

Kubernetes grafana operator support

  • The connector now supports being used with the Kubernetes Grafana operator as the GrafanaDataSource CRD. In the operator you specify the Cognite project in defaultProject parameter and the API URL as the clusterUrl parameter. In the operator you can specify a data source using the syntax below:
  - access: proxy
    editable: false
    isDefault: true
      clusterUrl: # other examples are, etc
      defaultProject: <cdf-project>
      oauthPassThru: true

2.5.0 - June 1, 2022

Relationships support

  • The connector now supports the CDF relationships resource type. Read more about relationships at Relationships documentation.
  • With relationships support you can now fetch time series based on relationships in the "Time series from asset" tab. Relationships can be filtered on data set, labels and active relationships based on the time filter selected in Grafana.
  • A new relationships tab has been added which can be used to utilize Grafana's Node Graph visualization plugin, or a new (alpha) custom visualization plugin which can be found at cognite-grafana-relationships-visualization

Templates support (preview)

  • A new templates tab has been added which support the CDF templates feature (preview). Enable this in the data source settings.
  • Using templates with Grafana will allow you to dynamically scale your dashboards when adding equipment.
  • Documentation:

2.4.0 - August 20, 2021


  • OAuth 2.0 client credentials grant flow to authenticate and authorize against CDF.

2.3.0 - June 1, 2021

  • Tabular representation of events data.
  • Event annotation query shows unfinished events by default.
  • Support for OAuth authentication with CDF.
  • Option to fetch only the latest data point for the time series.

2.1.1 - November 23, 2020

Bug fixes:

  • Support variables in time series by asset query. In version 2.1.0 $variable used as an Asset tag worked for earlier created dashboards, but it was impossible to create a new panel with the same capability.

2.1.0 - November 19, 2020

  • The data source requires Grafana version 7.0.6 or above.
  • Time series are now saved to dashboards by their externalId where possible. This allows you to switch between CDF projects that contain time series with matching externalIds.
  • Support for synthetic time series alignment.
  • Rewrote data source GUI to React.
  • Updated CDF logo to match light/dark theme.

2.0.1 - August 25, 2020

Bug fixes:

  • [Custom query] Option to display legend label as a plain text instead of expression

    Example for query: ts{id=1} + ts{id=2} + 1:

    • User label custom name results in custom name label. (No specific timeseries referenced in the label)
    • User label {{name}} results in timeseries_name_1 + timeseries_name_2 + 1 label. (This works the same way as before)
  • [Custom query] Improved error handling

    • HTTP 500 errors messages are visible from the GUI
  • [Custom query] Default granularity falls back to 1 second if shorter value is provided

    • Previously, selecting a time span less than 10 minutes resulted in a HTTP 400 error.

2.0.0 - June 29, 2020

General improvements

  • A new query language inspired by PromQL and compatible with synthetic time series in CDF. Learn more.
  • Support for all filtering capabilities available in CDF API v1 for the respective resource types (assets, events, times series).
  • Any future filtering capabilities added to CDF API v1 will be automatically supported by the data source (filters are passed directly to CDF).
  • Query expressions resulting in errors now displays error messages in the UI.
  • Regular expressions filtering can be used as part of the Query expression. The Filter field has been removed.
  • Supports CDF API v1, with no dependency to older API versions.
  • New documentation section for the connector, covering installation and administration, upgrades, feature documentation and getting started information.
  • Compatibility with Grafana 7.0. Learn more about the new capabilities here.

Time series and custom queries

  • You can now access time series that don't have the legacyName attribute populated with the data source.
  • Setting Root Asset in the Custom query tab is no longer required. This filter has been removed from the UI and is now available as part of a custom query expression. For example: ts{rootAssetIds=[12335453, 3455566]}.
  • Custom query aggregation requests are less likely to trigger rate limiting in CDF API.
  • Functions:
    • Support for string time series through the new map function allows you to convert string values to numeric values which can then be plotted by Grafana. For example: map(ts{externalId='pump_29'}, ['OPEN', 'CLOSED'], [1, 0], -1).
    • Use the on_error function to gain control over query calculations resolving with errors, such as division by 0. The function allows you to set a default value for individual data points that resolved with errors. Without the on_error function, the chart shows empty space in those places. Example: on_error(1/ts{externalId='canBeZero'}, 0).
    • Variable length functions: max(x1, x2, ...), min(...), avg(...).
    • The power function has been renamed to pow.
    • These functions are no longer supported: acos, asin, atan, ceil, celing, cot, degrees, floor, log, log2, log10, radians, sign, tan, atan2, mod, truncate, rand, crc32, conv, div.
  • These aggregates are no longer supported by custom queries: max, min, count, sum, continuousVariance, discreteVariance, totalVariation.
  • Short names for aggregation functions are no longer supported. Use full names instead: average, interpolation, stepInterpolation.
  • The timeseries{options} function has been renamed to ts{options}.
  • Filtering:
    • New options:isString=false, externalId='my_id', id=123, externalIdPrefix='my_'
    • Relate to asset tree with: assetSubtreeIds=[{id=754173880412890},{externalId="23-TE-96148"}], assetIds=[123, 234], assetExternalIds=['pump_1', 'pump_2'], rootAssetIds=[123, 234]
    • New range filters for create and updated time: createdTime={min=0, max= 1593018651}, lastUpdatedTime={min=1493018651, max= 1593018651}
    • Select time series based on dataSet membership: dataSetIds=[{externalId='Prediction Model A'},{id=123}]
    • path is no longer supported
    • See the full list of supported filters for the ts{} expression.


  • New filters: assetExternalIds, rootAssetIds, dataSetIds, externalIdPrefix, source.
  • Find active events in range with the activeAtTime filter. If endTime is null, the event is active from startTime onwards. The activeAtTime filter will match all events that are active at some point from min to max. Example: activeAtTime={min=1591018651, max= 1593018651}.
  • description supports only regular expression operators =~, !~, and !=.
  • minStartTime/maxStartTime has been replaced by the startTime={min=0, max= 1593018651} filter.
  • minEndTime/maxEndTime has been replaced by the endTime={min=0, max= 1593018651} filter, enabling you to also filter for events without the endTime set: endTime={isNull=true}.
  • minCreatedTime/maxCreatedTime has been replaced by the createdTime={min=0, max= 1593018651} filter.
  • minLastUpdatedTime/maxLastUpdatedTime has been replaced by the lastUpdatedTime={min=0, max= 1593018651} filter.
  • assetSubtrees has been replaced by the assetSubtreeIds=[{id=754173880412890},{externalId="23-TE-96148"}] filter which introduces support for Id/ExternalId input.
  • These filters are no longer supported: sort, dir, limit, offset, sourceId.
  • See the full list of supported filters for the events{} expression.


  • New filters: parentIds, parentExternalIds, rootIds, dataSetIds, externalIdPrefix, root.
  • The description field supports only regular expression operators =~, !~, and !=.
  • Select assets based on label: labels={contains={externalId="pump"}}, labels={containsAny=[{externalId="pump_type_A"},{externalId="pump_type_B"}]}, labels={containsAll=[{externalId="pump"},{externalId="rust_detected"}]}
  • assetSubtrees replaced by the assetSubtreeIds=[{id=754173880412890},{externalId="23-TE-96148"}] filter which introduces support for Id/ExternalId inputs.
  • minCreatedTime/maxCreatedTime has been replaced by the createdTime={min=0, max= 1593018651} filter.
  • minLastUpdatedTime/maxLastUpdatedTime has been replaced by the lastUpdatedTime={min=1592222651, max= 1593018651} filters.
  • These options are no longer supported: query, sort, dir, offset, boostname, path, depth, sourceId.
  • See the full list of supported filters for the assets{} expression.
