Skylight Analytics 20.04 Release Notes

Headline Features

Settings: Capture based alerting

Alert Policies
Alert policies now support monitoring of capture data if the associated feature is enabled. Policies can be managed from Settings > Policies > Alerting.
An individual capture alert policy may monitor 1 or more applications or zones (not both), and multiple threshold-based conditions can also be combined using metrics from the same layer. Capture alert policies also support a separate clear threshold for each alert condition.
Please note that secondary condition rules do not support ratio or duration parameters.

Analytics: Capture based alerting

Alert Monitoring
Alert Analysis
Alert metrics for capture data are available as a datasource for dashboards / analysis / reports.

Dashboards: Binning improvements

Dashboard Thresholding/Post-Aggregate Binning

Capture based post-aggregate binning

Post-aggregate binning for capture metrics will retrieve the top 250 records for a grouping sorted by a metric and count the volume of records with metrics in the specified bins. For example, in the above image there are 19 Client IPs that have a Client DTT over 15 seconds for the given interval.

Session based thresholding/post-aggregate binning

Post-aggregate binning for session metrics has been updated to show post-aggregate binning of objects by the percentage of an interval duration spent over/under a measurement threshold. For example, in the above image there is a Delay (max) >= 10ms threshold per object. The percentage of the interval crossing this threshold is computed per object and then binned. The results may also be grouped, in this case to by region.

Dashboards: Color Controls

Dashboard Color Schemes

Correlate timeseries colors using 3 color schemes: None (distinct per chart), Metric, or Category. Color schemes can be temporarily selected or persisted with the dashboard via authoring.
