Measures reported by CtxNsVsAuthTest

The AAA feature supports authentication, authorization, and auditing for all application traffic. To use AAA, you must configure authentication virtual servers to handle the authentication process. This process ensures that the access is granted only to an authorized user of the network.

If an authentication virtual server is rendered unavailable for a while or is unable to process authentication requests owing to an overload condition, unauthorized users may end up gaining access to critical data on the NetScaler. Sometimes, valid users may also be denied access. To avoid this, you can use this test to continuously monitor the state of your authentication virtual servers, track the flow of requests to and responses from each of these servers, and capture abnormalities before users notice anything amiss.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Server_state Indicates the current state of this authentication virtual server.   The values that this measure reports and their corresponding numeric equivalents have been listed in the table below:

Measure Value Numeric Value
Up 0
Down 1
Out of service 2
Transition out of service 3
Down when going out of service 4
Unknown -1

Note:

By default, this measure reports the above-mentioned Measure Values to indicate the current state of a virtual server. However, in the graph of this measure, virtual server states will be represented using the corresponding numeric equivalents - i.e., 0 or 1.

The Detailed Diagnosis of this measure shows the Service Type, Primary Port and the Primary IP address of the virtual server.
Data_received Indicates the amount of data received on this virtual server during the last measurement period. MB  
Data_transmitted Indicates the amount of data transmitted by this virtual server during the last measurement period. MB  
Requests Indicates the number of requests received by this virtual server during the last measurement period. Number A high value of this measure could indicate a potential overload.
Responses Indicates the number of authentication responses sent out by this virtual server during the last measurement period. Number If the number of Responses is way too less than the number of Requests, it could indicate a processing bottleneck on the authentication virtual server. This could result in genuine users being denied access or gaining delayed access to resources.
