Analyzing base station alarms
About base station alarms
An alarm is raised when a malfunction is detected on a specific base station. Each active alarm is associated with a severity that defines the importance of the service impact:
- CRITICAL (red): The service is affected. An immediate corrective action is required.
- MAJOR (orange): The service is partly affected. An urgent action is required.
- MINOR (yellow): A fault that does not affect the service should be corrected to prevent the problem from aggravating further.
- WARNING (blue): A potential or impending fault affecting the service should be diagnosed and corrected, if necessary.
- INDETERMINATE (purple): The severity cannot be determined.
An alarm is automatically CLEARED (green) when the resolution of the associated malfunction is detected. A CLEARED alarm remains in this state until the malfunction is detected again: in this case the alarm is raised again and moves to the associated severity.
To learn more about possible base station alarms and how to troubleshoot them, see Base station alarms.
Viewing the distribution of base station alarms per severity
The distribution of base station alarms per severity provides an overview of the malfunctions currently detected on your fleet of base stations. Alarms acknowledged by administrators are not taken into account in this distribution. See Viewing the list of base station alarms for more information on alarm acknowledgement.
-
In the left panel, select Alarms.
-
In BASE STATION ALARMS, a pie chart displays the distribution of base station alarms per severity.
Viewing the list of base station alarms
The list of base station alarms provides a complete view of the malfunctions currently detected on your fleet of base stations in order to take the appropriate corrective actions.
-
In the left panel, select Alarms.
-
In ALARMS DETAILS, clicking the Base Stations tab displays the list of base station 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 base station 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 Base station alarms.
- The Base Station Name and LRR-ID columns contain the identifiers of the base station for which the alarm is raised. Clicking on the name or the LRR-ID allows to navigate to the dashboard of the base station.
- 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 are entitled to a Base stations 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.
note
The 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 user. In this case, if the alarm has been triggered on a base station associated with a domain, the domain is displayed. For more information, see About domains.
Filtering base station 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 base station 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 Base Stations 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 base stations alarms dialog box that opens, restrict your search using the filters you want.
Filter Description LRR ID Retrieves alarms raised on a specific base station by providing its LRR ID. Tips You can copy and paste a LRR ID you get from the traffic shown by Wireless Logger application to investigate further a base station. Created after Retrieves alarms created after the specified date. Updated before Retrieves alarms updated before the specified date. Alarm name Retrieves a specific alarm by selecting its name in the list. For more information about base station alarms and their meaning, see Base station alarms. 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. -
Click Apply.
If the segregation based on domains has been enabled by an administrator user, a Domains filter allows to only display base station alarms associated with one of the specified domains. See About domains for more details.
Sorting base station alarms
You can sort the list of base station 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 Base Stations 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.
Configuring the "Unusually low uplink traffic level" alarm
If you are entitled to a Base stations manager role, you can define an inactivity alarm per base station and set one or two thresholds to trigger this alarm.
For more details, see Configuring the BS alarm #103.
Managing notifications for base station alarms
Email notifications
You can subscribe to email notifications for base station alarms in your user profile. For more information, see Editing your user profile.

SNMP notifications
SNMP notifications are available only on self-hosted ThingPark Enterprise. To use this feature, a platform configuration is required.
See:
- Device and base station alarm notification for Appliance/VM deployments
- Device and base station alarm notification for Kubernetes deployments.
SNMP allows to be notified of base station alarms by receiving SNMP traps on a SNMP server. Notifications of alarms via SNMP are added to the notifications of alarms via email.
SNMP traps are defined in the following MIBs:
