Alarms

Select the host name of an AP or a switch from the Devices table, and then go to Monitor > Monitoring > Alarms. The Device Details panel displays the following information:

• The Alarm Details widget displays the number of alarms for each severity level.
• There are two views available: Alarm Details (default view) and Timeline.
• The Alarm Details table lists all active alarms. Columns include:
  • Status: The status of the alarm.
  • Severity: Major, minor, or informational.
  • Category: The type of alarm, for example Agent alarm, Device disconnected, or Change OS.
  • Description: A description of the alarm.
  • Time Raised: The date and time when the alarm was reported.
  • Action: Actions that can be taken with this alarm.

  The following columns are optional:

  • Time Cleared: The time that the alarm was cleared.
  • Cleared by: The name of the person who cleared the alarm.
• The Alarms Timeline view displays an interactive timeline graph, with color-coded lines showing ALARMS RAISED, ACTIVE ALARMS, and CLEARED ALARMS. By default, the graph displays data captured for a 24-hour time frame. You can customize the time period using the Time Range controls:
  • To show events for the current day, select Day and then select the number of hours: 1, 2, 4, 8, or 24.
  • To show events for the week, select Week and then select the number of days: 1, 2, or 7.

  Select Active or Cleared to display the corresponding table.

For either view, use the UPDATE button to apply your changes to the devices. Use the refresh icon to refresh the data. Use the column picker to select which table columns to display. Your column selections persist, if you go to another window and return, and from one session to the next. The table features horizontal scrolling when there are too many columns to fit the display window.

To remove one or more alarms, or remove redundant entries, select the check box next to the alarm, and then select Clear Selected Alarms. Cleared alarms then become events, which appear in the Events log.

To clear multiple alarms at the same time, either select the check box in the table header to select all alarms, select the check boxes individually, or shift-select to select check boxes for multiple alarms. Then select Clear Selected Alarms.
