Calendar Heat Chart Views

Calendar heat chart views provide a month-long overview with hourly intervals that are color coded based on custom thresholds. The calendar shows one month with a colored block to show the status for each hour.

This view helps network engineers identify patterns in percentage-based metrics such as utilization, latency, and loss metrics. Identifying patterns can be a critical step in locating the source of performance issues that might appear to be intermittent. Usage patterns also aid in capacity planning.
The view also includes several pattern-matching filters to limit the data that appears:
  • Busy Hour
    View the hour each day with the highest value for the selected metric.
  • Business Week Pattern
    View patterns where the same hours have similar values on three or more days in the business week.
  • Calendar Week Pattern
    View patterns where the same hours have similar values on four or more days in the calendar week.
  • Repeating Hours by Business Day
    View patterns where the same hour on the same day of the business week has a similar value for three or more times in the month.
  • Repeating Hours by Calendar Day
    View patterns where the same hour on the same day of the calendar week has a similar value for three or more times in the month.
Maintenance indicators apply to all the devices and components in a site group. When the associated site group is selected in the context, maintenance indicators appear as shaded cells in the calendar heat chart. For more information, see Schedule Maintenance Indicators.
Calendar heat charts apply a lighter shading to show business hours. For more information, see Configure Business Hours Filtering.

Configure Calendar Heat Chart Views
Calendar heat charts include configuration options to set the threshold values for the colors to show in the chart. The view also lets you change the starting day and time display formats.
Because the color status thresholds are set in integers, this view works best with metrics that are gradable by integer, such as utilization. Metrics that have narrow ranges in value, such as percent errors, do not provide meaningful visualizations.
The IM Calendar Heat Chart lets you select the metric to show in the view. The built-in calendar heat charts on context pages have fixed metric selections.
For standard view configuration details, see Customize Views.
To configure the behavior of the calendar heat chart, specify the following properties:
  • Business Week Start
    Define the start of the five-day business week for the pattern-matching filters.
  • Time Display Format
    Specify whether the hours are identified with 12-hour or 24-hour time.
  • Green Zone Start
    Specify the threshold for the metric to show a normal status indicated with green.
  • Yellow Zone Start
    Specify the threshold for the metric to show a minor status indicated with yellow.
  • Orange Zone Start
    Specify the threshold for the metric to show a major status indicated with orange.
  • Red Zone Start
    Specify the threshold for the metric to show a critical status indicated with red.
You can configure calendar heat chart views to reflect reverse value severity. For metrics where low values are bad and high values are good, set Green highest and Red lowest. To omit a severity level, set the threshold value to zero. For example, setting Orange to zero removes the major severity when profiling metric thresholds.
