EV Observe : 5.3+

The forecast functionality is used to detect weak signals before alerts are generated, and in this way, help operations teams anticipate issues before they occur.

• Forecasts are applicable to configuration items (CI), i.e. hosts and services.
• They are performed using the metrics and statuses returned by a specific list of commands run by service templates on the Box.
• They meet different needs based on the forecast horizon: short-term forecast horizon (15-hour night-time) and medium-term to long-term forecast horizon (capacity).
• They are constantly reevaluated based on the latest data collected.
   

Forecasts: Objectives

• Enable the operations team to anticipate failure.
• Optimize SLAs by reducing unavailability.
• Process potential night-time alerts during the day when more employees are available to work on them.
• Minimize the costs and disorder that may arise from work during off-business hours.

Notes

• The commands compatible with forecasts are maintained by EasyVista. You cannot add new ones or modify existing ones.

Short-term forecast horizon: 15-hour night-time

The 15-hour forecast horizon enables you to avoid resorting to on-call staff during off-hours for incidents that could have been anticipated. This forecast horizon is applicable to operations integrated with a Dataviz.

Forecasts are available in the Graph widget (forecast mode), in the Status List widget and in the Details form of the configuration item (CI).

Calculation rules

• The system will apply a single rule to all CI metrics with thresholds. This rule will trigger an alert when either the maximum or minimum threshold limit is reached.
  • You define a status for each metric with thresholds. Thresholds are extracted from the most recent performance data returned by monitoring.
  • The final status of the CI is determined using the most critical metric status.

• To calculate the projected status or value, there must be at least 30 points of historical data, i.e. 30 values for the metric in question.

• The frequency for recalculating the forecast depends on the control interval.
  • Interval of 1 minute => Forecast recalculated every 5 minutes.
  • Interval of 5 minutes => Forecast recalculated every 15 minutes.
  • Interval of 10 minutes => Forecast recalculated every 30 minutes.
  • Interval of 15 minutes => Forecast recalculated every 30 minutes.
  • Intervals greater => Forecast recalculated each time a control is run.

Forecast in the Graph widget

The forecast is displayed as a dotted line in the chart.

Forecast in the Status List widget

• The report displays the projected status (15-hour), the status change deadline and the confidence level.
     

• You can click the projected status to create a ticket.
     

Forecast in the Details form of the CI

The Details form displays the projected status (15-hour), the status change deadline and the confidence level. The forecast is displayed in the Metric tab.

Medium-term to long-term forecast horizon

Calculation rules

The forecast is calculated using Average peak hour data.

Display

The capacity report contains a table that displays the current capacity rate, the capacity overrun deadline in months and days and the corresponding date.

• Components whose current capacity rate is already 100% and components whose capacity rate will not reach 100% within the forecast horizon defined will not be displayed.
• Components are sorted in ascending order based on their capacity overrun deadline. Components whose capacity overrun date is earliest will appear at the top of the table.
