Static placeholders for data without datapoints

Elastic Stack Kibana
1

When looking at a time segment, if there are no data-points it doesn't visualize it. For example, 10 sensors, 1 sensor stopped reporting a week ago, if I only look at 1 day increments, Kibana doesn't know how to visualize no data for sensors that are considered "Active" but haven't posted data. Is there a way to have a reference of what should be on the dashboard and handle no data correctly?

Thanks

Visualizations display aggregated results from documents in Elasticsearch. A visualization can not display anything if no documents exist in Elasticsearch.

You could solve this problem in a couple of ways

  1. Set up a Watch to be notified when data stops flowing.
  2. Set up an external process that inserts a document into Elasticsearch when a sensor stops reporting. Your visualizations could then display these "no data" documents.

  1. Is not feasible over 10k's of devices.
  2. Is a terrible idea filling ES null values just to visualize.
