Create Visualizations using DataPrepper integration

OpenSearch Dashboards
1

Versions (relevant - OpenSearch/Dashboard/Server OS/Browser): latest

Describe the issue: Unable to create visualizations for all metric types

Configuration: I followed this blog https://opensearch.org/blog/opentelemetry-metrics-visualization/

Relevant Logs or Screenshots: The blog shows how to create visualizations for data of type SUM, GAUGE, but no guidelines are left for metrics of type HISTOGRAM.

Please, I need your help on this. Which kind of visualization can I exploit for this case, and how can i configure the corresponding visualization?

@brice Are you referring to a Date Histogram? If so, that is available in many visualisations (i.e. Line, Horizontal Bar, Vertical Bar)

It is described in the very same blog.

@pablo
my main issue is how the metrics data appears at the level of the dashboard . there are so many fields: bucektcounts, bucketlist, bucketsmax, bucketsmin,…

i dont know how to properly exploit this data inorder to create accurate visualizations.
Below is a screenshot and json format of the data:
