Configure SNMP Traps for Subscriber Intelligence Solution
Real-time alerts for key resource and performance indicators within GTP engines can be accessed, such as:
|
■
|
Engine Approaching Tunnel/Session Limits : Alerts are generated when tunnel or session usage nears capacity |
|
■
|
GTP Persistence Restore Failure: Notifications are sent if the persistence file is stale or corrupted. |
|
■
|
Low Mempool Packet Buffers : Alerts indicate when packet buffer availability is running low. |
|
■
|
High CPU Utilization: Notifications are triggered as CPU usage approaches a user-defined threshold.
|
These alerts enhance visibility into system health, allowing for more efficient troubleshooting and operational oversight.
These alerts are generated once the said resource parameter is enabled in the GigaSMART Group. To enable these configuration follow the below steps:
|
■
|
From the left pane, go to Inventory > Physical > Nodes. |
|
■
|
Select the node, and then go to GigaSMART > GigaSMART Groups> GigaSMART Parameters. |
|
■
|
The GigaSMART Group parameters that need to be enabled are as follows: |
|
o
|
Enable Resource Packet Buffer - This allows configuration of Packet Buffer Usage Threshold values. A clear alert is triggered when the packet buffer usage falls 20% below the high threshold value. |
|
o
|
Enable Tunnel Usage Threshold- .This enables the configuration of tunnel usage thresholds. After enabling, configure the threshold values in the Maximum Tunnel Usage Threshold field within the range of 50-90%. The default value is 90%. If tunnel usage exceeds this configured value, an SNMP trap will be generated. A clear trap will be sent when the tunnel utilization drops to 10% below the high threshold value. |
|
o
|
Enable Session Usage Threshold- This allows configuration of session usage thresholds. After enabling, configure the threshold values in the Maximum Session Usage Threshold field within the range of 50-90%. The default value is 90%. If session usage exceeds this configured value, an SNMP trap will be generated. A clear trap will be sent when session utilization drops to 10% below the high threshold value. |
|
o
|
Enable Resource CPU Utilization -This allows the configuration of CPU utilization threshold values. A clear alert will be triggered when the CPU utilization drops below two-thirds of the high percentage value. |
Additionally, these threshold values can also be configured through the GigaVUE-OS CLI refer to snmp-server and gsparams in GigaVUE-OS CLI Reference Guide
Once these values are configured in the GigaSMART Group, it is possible to enable the required event for SNMP notifications either on the device or on the GigaVUE-FM instance managing the device. For instructions about how to enable SNMP notification on a device, refer to Enable or Disable Events for SNMP Notifications in GigaVUE Administration Guide.
To view the SNMP trap ,its corresponding Object Identifier and Events refer to Mapping of SNMP Traps with GigaVUE-FM Events and Alarms in the GigaVUE Administration Guide.
The threshold values for sessions can also be visualized under the Analytics tab Refer to Analytics
