Nikita Pande updated AMBARI-26504:
----------------------------------
Description:
The "Metrics" tab within a service's detailed view (e.g., Services > HDFS >
Metrics) is powered by the Ambari Metrics System (AMS) and Grafana. When you
define metrics and widgets in the {{metrics.json}} and {{widgets.json}} files ,
Ambari renders these pre-defined widgets on the service's "Metrics" tab.
h3. Creating a Custom Widget via the UI
Ambari provides a wizard to create new widgets directly from the UI, using the
metrics that Ambari is already aware of (i.e., those defined in
{{metrics.json}} and being collected by AMS).
# {*}Open the Widget Browser{*}.
# In the Widget Browser, click the *"Create Widget"* button (usually at the
top right of the dialog). This will launch the "Create Widget" wizard.
*Create Widget Wizard Steps:*
* *Step 1: Details*
*
** *Widget Type:* Choose the visualization type:
*** *Graph:* For displaying trends over time.
*** *Gauge:* For displaying a single value within a range (e.g., percentage
full).
*** *Number:* For displaying a single numerical value.
*** *Template:* For displaying combined text and metric values.
** Click {*}"Next"{*}.
* *Step 2: Metrics*
*
** This is the most critical step. Here, you select which metrics to include
in your widget.
** *Select Metric:* Choose a metric from the dropdown. This dropdown populates
from the metrics defined in your {{metrics.json}} for the current service.
** *Component:* Select the specific component (e.g.,
{{{}MY_CUSTOM_SERVICE_MASTER{}}}) that exposes this metric.
** *Aggregator:* For graph or number widgets, select an aggregation function:
*** *Avg:* Average value across all instances of the component.
*** *Max:* Maximum value.
*** *Min:* Minimum value.
*** *Sum:* Sum of values.
** *Add Operator: + - /* / ( )*
** *Add Metric:* Click this to add more metrics to the same widget (especially
useful for graphs with multiple lines).
** {*}Set Thresholds{*}: Warning and Critical
** Click {*}"Next"{*}.
* *Step 3: Name and Description*
* *Preview and Save*
*
** Review your widget configuration.
** The wizard will often show a preview of how your widget will look.
** Click {*}"Save"{*}.
Your newly created widget will now appear on the service's "Metrics" tab.
