Alarm Summary Report
The Alarm Summary Report is a standardized report generated in Network Director. It shows a graphical summary of the alarms that occurred within a specified period of time, node, and network view. The report has two portions: a report header and a report body.
This topic describes:
Alarm Summary Header
The report header provides file creation information about the report. The contents of the report header are described in Table 1.

NETWORK DIRECTOR REPORT
The type of report—in this case, the Alarm Summary report.
The date and time the report ran. The date format is: [Day of the Month] [Month] [Year]. The time format follows the Coordinated Universal Time (UTC). For example: 07 December 2012 11:35 PM PST.
The username of the user that generated the report.
The name of the report assigned when the report was created.
The report is generated from this view and node in the network. Perspective can be Logical view, Location view, or Device view of the network. Node represents the selected object upon which the report is based.
The period of time specified for data collection.
Alarm Summary Charts
The body of the Alarm Summary report contains a series of colored charts that provide insight into the trends or distribution of alarms in the network. The first chart summarizes the proportion of active and clear alarms. The rest of the charts are divided into two identical sets: one set for active alarms and one set for clear alarms. If there are no alarms in an active or in a clear state, the set of charts for that state are omitted.
The charts are:
Alarms by State—Shows the proportion of alarms in active and clear states.
Active Alarms by Severity (Clear Alarms by Severity)—Shows the proportion of alarms in each severity classification. The default severity levels are:Critical (Red)— A critical condition exists; immediate action is necessary.Major (Orange)— A major error has occurred; escalate or notify as necessary.Minor (Yellow)— A minor error has occurred; notify or monitor the condition.Info (Light Blue) —An informational message; no action is necessary.
In Preferences, administrators can override the default severity of an alarm and set the severity to match their inhouse guidelines.
Active Alarm Summary Chart (Clear Alarm Summary Chart)—Shows alarms by category and severity.
Active Alarms by Category (Clear Alarms by Category)—Shows the number of alarms in each alarm category and, within category, the number of alarms that are acknowledged or unacknowledged.
Active Alarms by Type (Clear Alarms by Type)—Shows the number of alarms of each specific type. The types are color-coded by severity.
Top 10 Sources of Active Alarms (Top 10 Sources of Clear Alarms)—Identifies the top 10 devices that are generating the most alarms. Shows the number of alarms each device is generating by severity.
Active Alarms by Timestamp (Clear Alarms by Timestamp)—This section of the report contains two graphs that plot alarms by their created timestamp:
Alarms by timestamp per severity—Plots each alarm of given severity against the time the alarm was created. For example, if during the time period covered by the report there are 10 alarms of major severity, the graph shows 10 orange data points that are plotted against the time the alarms were created.
Active alarms by timestamp for top 10 sources (Clear alarms by timestamp for top 10 sources)—For each source, plots the alarms generated by the source against the time they were created.
