Do you know what it takes to design a custom dashboard in VMware vCenter Operations Manager? If you ever wondered how big that deal is, this post will help you to achieve that.
What you want for creating a custom dashboard (in this example a storage monitoring interactive dashboard) is a heat map dashboard with a health tree, mashup charts and metric graph (rolling view). This is not there in the default storage performance dashboard. Before we roll on to show you how do you create this dashboard, we need to tell you what are the kinds of widget that we will be using and what are their purpose built in.
In most cases, you can select only from internally generated attributes that describe the general operation of the resources, such as health or the active anomaly count. When you select a single resource kind, you can select a metric for that resource kind.
The Health Map widget has a General mode and an Instance mode:
The widget displays a colored rectangle for each selected resource. The size of the rectangle indicates the value of one selected attribute. The color of the rectangle indicates the value of another selected attribute.
Each rectangle represents a single instance of the selected metric for a resource. A resource can have multiple instances of the same metric. The rectangles are all the same size. The color of the rectangles varies based on the instance value. You can use instance mode only if you select a single resource kind.
In either mode, you can group the rectangles according to tag type and select the color range to use. By default, green indicates a low value and red indicates the high end of the value range.
When you point to the rectangle for a resource, the widget displays the resource’s name, group-by values, and the current values of the two tracked attributes. You can click Show Sparkline in the pop-up window to review a small sparkline of the tracked metric by the heat map color.
