Radius Health Check - Cisco ISE

When the ISE Health System rule is  evaluated, system health parameters are examined as a result of values exceeding  the rule for a specified time interval (up to the previous 60 minutes).

When  the ISE AAA Health rule is evaluated, ISE health parameters that exceeded the  rule for the specified time interval (up to the previous 60 minutes) are  examined. Cisco ISE monitors the following parameters:

• RADIUS  throughput

• RADIUS latency

If any of the parameters exceed the rule, an  alarm is triggered. By default, the rule applies to all monitored Cisco ISE  instances. However, you can choose to limit the check to just a single Cisco ISE  instance

Thanks for your input. Please can you provide any configuration example and reference docs. I want to use an AD user.

For example if we have too many authentications per second, more than what the PSN Specifications are designed for. In such cases we've to distribute the radius load to other PSN’s. You can also run Catalog report to draw a graph of Radius latency per PSN instance under Operations>Catalog>Server Health Summary> Last 7 days> PSN Hostname.

This will only give you a trend of radius latency but not the reasons why. You need to go through logs of the concerned PSN to find out whats going on the PSN. Certainly Radius latency greater than 3 Seconds is concerning. In such scenarios we have to download the support bundle and analyse the logs.

I will appreciate if some one can provide switch side configuration example for Radius Health check.
