Alerting page

The Alerting page in the Web Console is divided into three sections:

alerting-main

Options header

The options header allows you to Filter or Group results on the page in order to focus on only the relevant information.

You can Group by one or more attributes or dimensions. You will see a prompt to start the expression when typing in the field.

The Alerts section will change to a folder based list when grouping is enabled.

alerting-folders

You can Filter by one or more attributes or dimensions. You will see a prompt to start the expression when typing in the field.

When data is grouped, filters operate at the group level so that a group is included in the displayed results if any of its children are included in the filter. Children that do not match the filter are also displayed as part of the group.

Alerts section

The Alerts section shows a list of all alerts received in the selected time interval in chronological order.

Field Description
Dimension Shows the entity that triggered the alert by listing its dimensions in hierarchical order.
Severity Severity level of the alert. Colour coded to match the highest severity.
Age Time since the alert was triggered.

Signals Section

This section shows all signals contributing to an alert. Alerts are organised hierarchically so that the signals section of a selected entity shows the severity of its children as signals.

A parent entity inherits the maximum severity of its children. However, if an entity is snoozed then its severity is not taken into account when determining the severity of the parent entity.

You can expand a specific signal to see the changes in that metric over time. An expanded signal shows the changes to severity status on the left-hand side and the changes to the value of the metric on the right-hand side.

Snooze

An entity is snoozed if it has the snoozed attribute. Currently, Snooze messages are only sent by Geneos based on user-actions in Active Console.

The snoozed attribute can have one of the following string values:

["Obcerv"] ["User Guide"]
