Increased flexibility for managing workloads during peak/off-peak hours through schedule-based rules.
See Create workload rules in the Workload Management manual.
|Analytics Workspace||Create categorical charts (line, column, area, time-column) and run analytical operations on metrics and accelerated datasets.
Add reference lines to metrics data for comparison/analysis.
Create fast and highly performant streaming alerts.
Visualize events data timeline along with metrics for root-cause analysis.
Expanded time-range picker provides better control over the data to analyze.
