12.3 Alarms Widgets
Alarms widgets provide various ways to visualize and interact with alarm events — from tabular views and timelines to topology diagrams and pie charts. Most of these widgets are designed to work in combination with the Time range widget (see Section 12.1) and optionally with other context-providing widgets such as Location filter or State panel.
Alarms Table
The Alarms table widget displays a fully customizable table of alarm events for monitoring objects. It always requires a linked Time range widget, plus additional widgets depending on the selected operating mode.
Operating Modes
The operating mode is set using the Alarms by field in the widget parameters:
| Mode | Description | Required companion widgets |
|---|---|---|
| Locations | Shows alarm events for a selected location | Location filter (12.3), Time range (12.1) |
| Specific object | Shows alarm events for a single monitoring object | Time range (12.1) |
| State panel | Shows alarm events for objects in a selected state panel | State panel (12.1), Time range (12.1) |
| Video wall panel | Shows alarm events for objects in a selected video wall | Video wall panel (12.1), Time range (12.1) |

Parameters
Table 62. Alarms table widget parameters
| Parameter | Applicable modes | Description |
|---|---|---|
| Font size | All | Font size of the alarm events table |
| Object | Specific object | The monitoring object whose alarm events are shown |
| State panel | State panel | The state panel whose alarm events are shown |
| Video wall | Video wall panel | The video wall whose alarm events are shown |
| Show only active alarms in NOW mode on Timerange | All | When enabled, only currently active alarms are shown when the linked Time range widget is set to the NOW position |

Location Filter
The Location filter widget displays the location tree from the MultiProbe configuration and acts as a filter controller for compatible widgets in the same workspace — primarily the Alarms table widget. When a user selects a location in this widget, the linked widgets automatically update to show data for that location.
The widget has no configurable parameters.

Object Timeline
The Object timeline widget visualizes alarm event history for a monitoring object as a color-coded horizontal timeline. The color of each segment corresponds to the alarm priority at that time, following the scale defined in Section 5.3. The widget requires a linked Time range widget.
To configure the widget, select the monitoring object from the list (Figure 294).

Hovering over any point on the timeline displays a tooltip with details about the alarm event at that time.

Scheme
The Scheme widget displays a topology diagram along with the real-time statuses of the objects it contains. This is useful for visualizing the state of a monitored infrastructure in a graphical, layout-based format.
The diagram can be displayed in two modes:
- Detail diagram view — includes object names and full-size icons.
- Compact diagram view — shows reduced icons without object names, useful for high-density diagrams.
To configure the widget, select the diagram and the desired display mode (Figure 296). Enable Show mini map to display a reduced overview map in the bottom-right corner of the widget — this is helpful for navigating large diagrams that extend beyond the visible area. The mini map can be toggled on or off at any time using the dedicated button during visualization.

SLA Pie Chart
The SLA pie chart widget shows the distribution of alarm event states over a selected time period as a pie chart. It is used for SLA reporting and at-a-glance reliability assessments for monitoring objects or virtual services. The widget requires a linked Time range widget.
To configure the widget, select the type of object to analyze — Monitoring objects or Virtual service — using the corresponding tab, then choose the specific object (Figure 298).
Figure 298. SLA Pie Chart widget parameters
In the visualization, hovering over a chart segment displays a tooltip with details about the corresponding alarm state. Click any entry in the legend to include or exclude that alarm state from the statistics. The legend can be toggled on or off using the legend button.

Virtual Service
The Virtual service widget displays the topology of a virtual service along with the real-time statuses of its component objects. It works similarly to the Scheme widget but is specific to virtual services configured in MultiProbe.
The visualization supports two display modes:
- Detail diagram view — shows object names and full-size icons.
- Compact diagram view — shows reduced icons without names.
To configure the widget, select the virtual service and the desired display mode (Figure 300). Enable Show mini map to display a navigation overview in the bottom-right corner, which can be toggled on or off during visualization.
