This is a data source plugin for Grafana that pulls in cumulative and point in time metrics from a backend YottaDB metrics server.

This "front end" plugin relies on a YottaDB metrics back end server to operate. For details on setting up the back end server, please see here:

https://github.com/RamSailopal/YottaDB-Grafana-Server

On first using the plugin as a datasource for a dashboard panel, the plugin will acculumate all cumulative metrics over time. In order to see specific metrics, click on the individual label as in the graphic below which show SET metrics

The field CUM,POT or CUS will dictate the catergory of metrics to attain:

CUM - Cumulative metrics over time

POT - Metrics over a single point of time

CUS - Custom metrics. Calling a specific function and routine to attain metrics.

The field YottaDB region will dictate the YottaDB region to attain metrics for. Left blank, the region will be the default, DEFAULT region

The Number of records to attain field will dictate how many records are "pulled" from the back end API server. Enter all for all available data.

NOTE - A higher count will effect performance

All other fields are specific to custom metrics. Details about these field are available on the Grafana backend server pages (linked above)

Following on from the grafana-server README (linked above) An example of the use of custom metrics is show in the video below (click to view on YouTube):

As fields are type independant when first attained, they will need to be set from the default string type to time/numeric types with transformation/field conversion.

A gitpod demo of the plugin is available here:
