Overview
The entity overview page provides detailed information about a particular entity. From this page you can monitor both the instantaneous and historical value of metrics associated with the entity.
The entity monitoring page is composed of four sections:
- Attributes — shows the values of important attributes of the selected entity.
- Metrics — lists all the metrics associated with the selected entity.
- Metric history — shows a graph of the selected metric's value over time.
- Related events — lists the events related to the selected metric.
Attributes
The Attributes header shows the current value of five of the attributes associated with the selected entity. The selection of attributes shown can be configured from the Attributes list.
To open the Attributes list click the See all attributes button.
Attributes list
The attributes list shows all the available attributes, their type, and their value for the selected entity. The first five attributes are shown in the Attributes header of the entity overview and in the tooltips on the Monitoring page.
The order of the Attributes list is user configurable, to change the order:
- Click the Edit order button.
- Drag the Attributes into the desired order using the handles.
- Click Done.
Note: Changes to the order of attributes will effect all entities and will also change which attributes appear in tooltips.
