RADIUS Alerts for Client Devices
Overview
The Nile Access Service continuously monitors the RADIUS authentication transactions across all connected client devices. When a significant percentage of clients encounter RADIUS failures, the Nile Access Service generates alerts to notify the network administrators.
RADIUS Alert Thresholds
The Nile Access Service uses the following thresholds to determine when to generate RADIUS alerts:
5% to 10% Client Failures
If 5% to 10% of the clients attempting RADIUS transactions in the last 15 minutes have encountered failures, the following alert is generated:
RADIUS Alert: 5% <= Clients < 10% <# number> of clients attempting RADIUS transactions in the last 15 minutes encountered failures at <site> for <x hrs/mins>
10% to 25% Client Failures
If 10% to 25% of the clients attempting RADIUS transactions in the last 15 minutes have encountered failures, the following alert is generated:
RADIUS Alert: 10% <= Clients < 25% <# number> of clients (>10%) attempting RADIUS transactions in the last 15 minutes encountered failures at <site> for <x hrs/mins>
25% to 100% Client Failures
If 25% to 100% of the clients attempting RADIUS transactions in the last 15 minutes have encountered failures, the following alert is generated:
RADIUS Alert: 25% <= Clients <= 100% <# number> of clients (>25%) attempting RADIUS transactions in the last 15 minutes encountered failures at <site> for <x hrs/mins>
Alert Lifecycle
The RADIUS alert is "closed" when the condition is cleared, i.e., when less than 5% of the clients are encountering RADIUS failures.
Alert Categorization and Visibility
The RADIUS alerts are categorized as "Client Devices" in the Nile Cloud Services Portal's alert table. When a user clicks on the alert, they are taken to the "Devices" page, which displays the filtered list of devices with the corresponding RADIUS errors.
By providing these RADIUS alerts, the Nile Access Service helps network administrators quickly identify and address any issues related to RADIUS authentication, ensuring the seamless operation of the network infrastructure.
