For example, you might choose to set critical severity for data points falling below the 1st percentile (0.01) and above the 99th percentile (0.99).īecause you must choose percentile threshold values between 0 and 1, this is the only algorithm that will never produce thresholds above or below your historical data minimum and maximum values. Lets you put threshold bounds at various percentiles based on historic data. The following template types are available: You can use adaptive thresholds with aggregate thresholds but not per-entity thresholds. Use adaptive templates to create time polices that generate thresholds dynamically and update daily based on changes in your data. Use static templates to create time policies that do not change after you configure them. Thresholding templates are either static or adaptive. You can select templates with different time block combinations, such as work hours, off hours, weekends, AM/PM, 3 hour block, 2 hour block, and so on. ITSI provides default thresholding templates that you can use to build your time policies. When you create a new time policy, the previous time policy is overwritten and cannot be recovered. You can only have one active time policy at any given time. Updates are also applied to any services or service templates using those KPIs. Any updates you make to a KPI threshold template are applied to all KPIs using that template, overriding any changes made to those KPIs. IT Service Intelligence (ITSI) stores thresholding information at the KPI level in the KV store. Time policies accommodate normal variations in usage across your services and improve the accuracy of KPI and service health scores.įor example, if your organization's peak activity is during the standard work week, you might create a KPI threshold time policy that accounts for higher levels of usage during work hours, and lower levels of usage during off-hours and weekends. Use time-based static thresholds if you know the workload schedule for a specific KPI. Time-based static thresholds let you define specific threshold values to be used at different times to account for changing workloads over time. Create time-based static KPI thresholds in ITSI
