System Health

The System Health page is a dashboard for three categories of system issue: Product Health, Reboot Status, and System License. For each category and its constituents: Status [color dot indicator]; Time; Reason.

Note that recipients (refer to the Recipients topic for a description) for system health notifications are configured on the Administration > System Settings:System Health Notifications page; see the “System Health Notifications” topic for details.

– SU Controller Temperature – This indicates that the temperature has exceeded the threshold for safe operation specified by the component manufacturer.

Model	Storage Unit Controller Temperature (degrees C)
SCAN-SU-48TB, SCAN-SU-72TB	100
SCAN-SU-4, SCAN-SU-10	100

– Chassis Health – This indicates the status of the system itself, reflecting the Chassis Availability status on the Storage Configuration > Hardware Status page, and changes if any hardware attached to the system (such as Storage Units) changes in its availability status. This indicator does not take into account the overall status of components within the system, such as disks or sensors. The overall Health status shown per chassis on the Storage Configuration > Hardware Health page does take those components into account, however.

– Exhaust Air Temperature – This indicates that the temperature has exceeded the threshold for safe operation specified by the component manufacturer.

Model	Exhaust Air Temperature (degrees C)
2170	85
4170, 6170, 8170	80
SCAN-SU-48TB, SCAN-SU-72TB	100
2180	75
4180, 8180	75
SCAN-SU-4, SCAN-SU-10	46

– Intake Air Temperature – This indicates that the temperature has exceeded the threshold for safe operation specified by the component manufacturer.

Model	Intake Air Temperature (degrees C)
2170	50
4170, 6170, 8170	60
SCAN-SU-48TB, SCAN-SU-72TB	33
2180	45
4180, 8180	45
SCAN-SU-4, SCAN-SU-10	no sensor

– CPU Temperature – This indicates that the temperature has exceeded the threshold for safe operation specified by the component manufacturer.

– Disk Health – This indicates the health of each disk in the system, rolling up the worst severity of any disk installed in the system, based on its status as shown on the Hardware Health page, as follows:

– Data Volume Status – This is orange or red if the storage volume provided by a Storage Unit or head unit is failing/rebuilding, or has failed (for example, due to a disk failure or removal).

– Power Supply – This indicates if the power supply is missing, or if firmware has identified an error in the component’s behavior.

– System Fan – This indicates if the fan is missing, or if firmware has identified an error in the component’s behavior.

– Flow Export Connection – For an AppResponse system that is connected to a NetProfiler system, this indicates if there is an error in the connection that prevents the exchange of data.

– Time Synchronization – This indicates a problem if NTP or PTP is enabled, and the system has not synchronized to a clock for 60 seconds. (It checks every 30 seconds, and triggers if two consecutive checks show that the clock is not synchronized.)

– WTA Configuration – This indicates the existence of any WTA errors.

– Analysis Packet Drops – This indicates problems when the Packet Analysis module is too slow in processing packets that are being captured.

– Capture Job Packet Drops – This indicates packets being dropped because the disks are too slow in writing packets to the packet storage.

– Monitoring Interface Packet Drops – Drops are occurring at the input level because the system is too slow in processing the packets coming from the network card, or there is insufficient buffer space left to copy new incoming packets.
