Viewing the Daily Historical Alarms Graph
The daily graph in the Alarms panel shows the historical alarm count over the past month. This information is useful for determining the times and durations of outages in the past month and can be used to correlate against trouble tickets or past network maintenance periods. It is also useful to help you spot network trends and to correlate the trends with other network activity such as the introduction of new nodes or software.
This procedure helps you identify the network elements that raised the alarms and to see the details of the actual alarms raised.
The examples in this section show a high number of alarms. This is for illustration purposes only.
- In the Alarms panel on the proNX Service Manager Dashboard summary
page, click the Daily tab.

To change the scale of this graph, see Changing the scale in line and bar graphs.
This graph is updated periodically based on a configurable setting (see Changing the proNX Service Manager Dashboard Settings), or on a browser refresh. The default update period is 30 minutes.
- Hover over a data point to see the actual alarm count for that day.
- Click on a data point to see the breakdown of those alarms
by network element for that day.
A table pops up showing the network elements with alarms at that severity for that day, sorted by number from most to least.
- To view the actual alarms at that severity for a particular
network element, click on the Alarms Total for that network
The historical alarms table appears, filtered for the network element, severity, and day that you selected.
