A dashboard chart widget contains a visual representation of events. You can represent a chart as a bar or line chart and either can be displayed as a stack.

There are several ways to represent charts:

  • Charts can contain a lot of information. Avoid having more than two chart widgets in a single row. In some rare cases, three chart widgets can be used effectively, but more than three is strongly discouraged. When determining whether chart widgets are readable or not, be sure to use the minimum resolution supported by vRealize Log Insight, which is 1024 x 768 pixels.

  • If any row except the last row has a single chart widget, then make that widget full-width

  • When naming a chart widget, use a descriptive title and avoid cryptic field names. For example, an extracted field is called vmw_error_message. Instead of calling a chart Count of vmw_error_message, call it Count of error messages

  • You can save similar charts and stack them in the same column of a dashboard group for visual comparison. For example:

    • Average X of events over time + Maximum X of events over time. Given the different functions used, the Y-axis of the charts might have a different scale.

    • Count of events over time grouped by X + Count of events over time grouped by Y.
