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: Playback. Clear, interactive graphs present alarm data ordered by rule, area and time, as well as displaying System Alarms.

Querying

To make an alarm query, select the Time Period required. The default time period will be 24 hours, but a period of 48 or 72 hours can be selected. The user can also export the data by selecting the export icon.

The results are automatically calculated and will be presented in the four graphs below; a Rules bar graph, an Area bar graph, an Alarms by Time line graph and System Alarms line graph. In the example below, the alarm query is showing the last 48 hours:

The example illustrated here tells us:

• There have been 17 alarms in the past 48 hours.

• Of those alarms, the Path area had the most - 15.

• There was a spike in the frequency of all alarms at around 14:30 on the 13th October.

Rules: It is possible to adjust the alarm results displayed in the Alarms by Time line graph by 'deselecting' rules and areas, through clicking on their bars. This will remove that rule's alarm data from the accumulated data displayed in the line graph, 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 blue.

Areas: This displays the areas where an alarm has been triggered. Again, it is possible to adjust the alarm results displayed in the Alarms by Time line graph by 'deselecting' rules and areas, through clicking on their bars:

Alarms by Time: there are two alarm line-graphs; Alarms by Time and System Alarms. 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. The numbering alarms per specific hour can be identified by hovering the cursor over the points of the line graph:

System Alarms: represents the alarms caused by any system fault or failure over the time period selected.
