Introduction
The purpose of the Alarm Dashboard is to give an overview of recent alarms at a glance, without having to utilise the Playback Query function. Clear, interactive graphs present alarm data ordered by Rule, Section and Time, as well as displaying System Alarms, Queues and Stopped Vehicles.

Querying
To make an alarm query, three simple options need to be input in the Alarm Query Bar:
...
Select the Export button in order to export and save Alarm Query data.
Rules
...
It is possible to adjust the alarm results displayed in the Sections and Alarms by Time line graphs by 'deselecting' rules, through clicking on their bars. This will remove that rule's alarm data from the accumulated data displayed in the two line graphs, and could be useful if a scale is skewed by a particular rule's alarm count being far higher than any other. A 'deselected' rule is indicated by changing from opaque to translucent magenta. The example below is the 'deselection' of the Debris rule, and therefore the Sections and Alarms by Time line graphs only display Person and Slow rule alarm data:
...
Sections
There are two Sections graphs; Alarm Count and Top Alarm Sections. The Alarm Count line graph by default depicts the accumulated alarms per section of all Rule Types. The exact number of alarms in each section can be identified by hovering the cursor over the points of the line graph:
...
The Top Alarm Sections pie chart breaks down the Alarm Count in each section into their comparative proportional values. It also lists the sections into descending order of Alarm Count. Hovering the cursor over individual sectors in the pie chart will highlight which section they represent in the list below:

Alarms by Time
There are three Alarms by Time line-graphs: Section Alarms, System Alarms and Queues. Each represents the spread of alarm frequency over time. The default time period will be 24 hours, but a period of up to 72 hours can be selected to be represented in an Alarm Query. The numbering alarms per specific hour can be identified by hovering the cursor over the points of the line graph:

If there are unusually few alarms on first glance at the Rules graph, then it may be useful to go straight to the System Alarms graph to see if there have been any errors in the system that have prevented usual rule and alarm generation. |
