Analyzing multicast group alarms
About multicast group alarms
An alarm is raised when a malfunction is detected on a specific multicast group. To learn more about alarms, see Device alarms.
Viewing the list of multicast group alarms
The list of multicast group alarms provides a complete view of the malfunctions currently detected on your multicast groups in order to take the appropriate corrective actions.
-
In the left panel, select Alarms.
-
In ALARMS DETAILS, clicking the Multicast Groups tab displays the list of multicast group alarms.
-
By default, alarms that are either cleared or acknowledged are hidden because they don't require any corrective action, and last updated alarms are displayed first. The default filtering and sorting options can be customized, see Filtering multicast group alarms for more details.
-
The State column either contains the severity of active alarms, or displays CLEARED for already cleared alarms. An occurrence number may be displayed on the alarm state. To learn more about the meaning of the occurrence number for each type of alarm, see Device alarms.
-
The Multicast Group Name and DevEUI columns contain the identifiers of the multicast group for which the alarm is raised. Clicking on the name or the DevEUI allows to navigate to the dashboard of the multicast group.
-
Expanding an alarm, as shown in the preceding screen, displays the alarm's details and the troubleshooting actions to solve the associated malfunction. The VIEW ALARM HISTORY button displays the list of the past instances of the same alarm in the last 15 days. The displayed severity in this list is the last severity reached by the alarm before clearance.
-
If you have a Devices, multicast groups and connections manager role, you can acknowledge selected alarms by clicking
. Acknowledging an alarm is useful if you consider it as being not important and you do not want to see it in the list of active alarms.
noteThe acknowledgment will be automatically reversed if the severity of the alarm increases. While an alarm is acknowledged, no email notification is sent for that alarm.
-
The Domains column is only available if the permission segregation based on domains has been enabled by an administrator. In this case, if the alarm has been triggered on a multicast group associated with a domain, the domain is displayed. For more information, see About domains.
-
You may export the list of alarms associated with your current filters,
by clicking the button above the list.
Filtering multicast group alarms
By default, alarms that are either cleared or acknowledged are hidden because they don't require any corrective action. You can change the default filters to extend or restrict the list of multicast group alarms. If you change filters, your selection is saved and will apply by default for next sessions on the same computer.
-
In the left panel, select Alarms.
-
In ALARM DETAILS, select the Multicast Groups tab.
-
If Active filters is displayed:
- To clear all active values of a same filter, click the filter cross.
- To delete all active filters, click Clear all.
- To edit the active filters, click Edit filters.
-
If no filter is active, click Add filter.
-
In the Filter multicast groups alarms dialog box that opens, restrict your search using the filters you want.
Filter Description DevEUI Retrieves alarms raised on a specific multicast group by providing its DevEUI. Tips You can copy and paste a DevEUI you get from the traffic shown by Wireless Logger application to investigate further a multicast group. Domains Retrieves alarms triggered on multicast groups associated with one of the specified domains. This filter is only available if the permission segregation based on domains has been enabled by an administrator. For more information, see About domains. Created after Retrieves alarms created after the specified date. Updated before Retrieves alarms updated before the specified date. Clearance status Filters alarms based on their state: only Active alarms (with a state different than CLEARED), only Cleared alarms (with a state equal to CLEARED), or All alarms. Minimum severity Retrieves active alarms having a severity equal to the selected severity or higher. This filter is only applicable when the Clearance status filter is set to Active. Ack status Filters alarms based on their acknowledgement status: only Not acknowledged alarms, only Acknowledged alarms, or All alarms. -

Sorting multicast group alarms
You can sort the list of multicast group alarms to prioritize corrective actions. If you change the sort, your selection is saved and will apply by default for next sessions on the same computer.
-
In the left panel, select Alarms.
-
In ALARM DETAILS, select the Multicast Groups tab.
-
You can sort alarms by clicking the arrow of the following column headers:
- State: Sorts alarms by state in ascending or decreasing order. Alarms sharing the same state are then sorted by last update in decreasing order.
- Acked: Sorts alarms by acknowledgement status in ascending or decreasing order. Alarms sharing the same acknowledgement status are then sorted by last update in decreasing order.
Managing notifications for multicast group alarms
The same notifications than for device alarms are available, see Managing notifications for device alarms for more details.
