Viewing the Hourly Historical Alarms Graph
The hourly graph in the Alarms panel shows the historical alarm count over the past 24 hours. This information is useful for determining the times and durations of outages in the past 24 hours and can be used to correlate against trouble tickets or recent network maintenance periods.
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 Hourly tab.
A plot depicting the number of alarms that have occurred in each of the last 24 hours is displayed.
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 hour.
- Click on a data point to see the breakdown of those alarms
by network element for that hour.
A table pops up showing the network elements with alarms at that severity for that hour, 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 hour that you selected.
