Cisco Systems NAM Top N Sites by Alarm Count, Top N Hosts by Site and Alarm Count, Last 50 Alarms

Chapter 3 Monitoring and Analysis

Alarm Summary

Note You could see a count of two alarms for the same occurrence if:

-both the source and the destination are in the same site in the Top N Site - Host Pair chart.

-both the source and the destination are in the same site in the Top N Site chart.

-both the source and the destination are in the same site using the same application in the Top N Site - Application Pair chart.

Note You will not have any data in Top N Site - Application and Top N Application if there is no threshold configured that involves an application (for example: Response Time threshold or Application threshold).

NDE Interface alarms are not related to any site; therefore, they will not appear on the four colored site alarm charts on the Alarm Summary dashboard. Instead, the New Alarms Raised and Last 50 Alarms tables at the bottom of this screen will contain NDE Interface alarms raised.

The five charts displayed on the Alarm Summary dashboard are:

•Top N Sites by Alarm Count

This chart will list the Top N sites (maximum of 10) that have the most alarm triggers during the selected time range. If no thresholds are configured, this chart will have no data.The number on the bottom of the chart is the alarm count.

You can configure thresholds under Setup > Alarms > Thresholds. You can configure the Top N entries under Administration > System > Preferences.

•Top N Hosts by Site and Alarm Count

This chart shows the number of alarm messages during the selected time range that are triggered for Hosts across all sites, by the Site - Host Pair.

•Top N Applications by Alarm Count

This chart shows the number of alarms during the selected time range for Applications across all sites.

•Top N Applications by Site and Alarm Count

This chart shows the most alarm triggers during the selected time range by the application and site pair.

•New Alarms Raised

The New Alarms Raised table shows you all alarms that occurred during the interval selected in the Interactive Report window. Some alarms may have been triggered outside of the time period, but may still be occurring.

You can use the Filter drop-down menu to filter the alarms.

•Last 50 Alarms

The Last 50 Alarms table shows you the alarms that occurred during the interval selected in the Interactive Report window. Some alarms may have been triggered outside of the time period, but may still be occurring.

You can click the “All Alarms” button at the bottom to bring up a separate window, which will show you all 50 alarms without the need for scrolling.

You can also use the “Filter” button, both on this screen and the “All Alarms” screen, to display only alarms that meet the criteria you enter.
