1. Alarm List
By default, Alarm List displays the uncleared alarms. You can select alrm type, level and cleared status to filter alarms. Alarm List supports the search based on AP serial number, alarm type, alarm source (network/device), and alarm generation time.
You can configure thresholds in Alarm Settings.
The following describes the conditions for generating alarms.
Type |
Condition |
Description |
Device goes offline |
An AP goes offline. |
The AP is disconnected from the Cloud Service, or the AP is powered off. |
Device goes online and offline continually |
The online/offline change times of an AP exceeds the default threshold within two hours. |
The connection between the AP and the system is unstable or the AP has a firmware or hardware fault. |
All devices are offline |
All APs in a network go offline. |
N/A |
High channel usage on AP |
The RF channel utilization exceeds 80%. |
RF channel utilization is high and interference is strong. It is recommended to change the channel. |
System usage(CPU/memory usage) above threshold |
The CPU or memory usage of AP/switch/gateway exceeds the threshold.
|
For AP, the default threshold for CPU usage is 85% and for memory usage is 85%. For switch, the default threshold for CPU usage is 50% and for memory usage is 65%. For gateway, the default threshold for CPU usage is 50% and for memory usage is 65%. Custom values are not supported.
|
Switch RLDP |
A loop occurs on the switch. |
N/A |
Abnormal network access on gateway |
The gateway port fails to ping the specified domain or IP for several times. |
When the Ping test failed for the specified times, the alarm is sent. The times and domain/IP address can be configured manually. |
High packet loss rate on gateway |
The packet loss rate of gateway exceeds the threshold. |
When the packet loss rate exceeds the specified percentage of threshold for several times in 5 minutes, the alarm is sent. The times and threshold can be configured manually. |
Uplink rate above threshold on gateway |
The uplink rate exceeds the specified percentage of threshold for several times. |
When the uplink rate exceeds the specified percentage of threshold for several times, the alarm is sent. The threshold, times and percentage can be configured manually. |
Downlink rate above threshold on gateway |
The downlink rate exceeds the specified percentage of threshold for several times. |
When the downlink rate exceeds the specified percentage of threshold for several times, the alarm is sent. The threshold, times and percentage can be configured manually. |
SIM card traffic exceeds limit |
SIM card traffic exceeds a default threshold. |
