Citrix FAS Details Test

The efficiency of Citrix FAS can be best evaluated by understanding its workload in terms of user sessions and certificate requests, and measuring how quickly it processes this workload. With the Citrix FAS Details test, administrators can do that and more!

This test reveals the count of active sessions on Citrix FAS and the count of concurrent certificate signing requests to it, thus providing administrators with a measure of the load on the server. The test further 'qualifies' the load as high, medium, and low, thereby enabling you to promptly detect overload conditions. Also, by reporting the average time taken by FAS to service the CSR requests and the rate at which requests are typically serviced, eG Enterprise reveals how efficiently FAS processes the requests. This way, eG Enterprise also brings processing bottlenecks to light.

Target of the test : Citrix Federated Authentication Server

Agent deploying the test : An internal agent

Outputs of the test : One set of the results for the Citrix FAS server being monitored

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed. By default, this is set to 5 minutes.


The IP address of the host for which this test is to be configured.


The port at which the specified host listens.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

Active sessions

Indicates the number of connections currently active on FAS.


These are good measures of the current workload of the Citrix FAS server.

Concurrent CSRs

Indicates the number of certificate requests processed at the same time.


Private key operations performed

Reports the five minute rolling average of the number of certificate private key operations being performed by the FAS.



Request time

Indicates the length of time to generate and sign a certificate.


Ideally, the value of this measure should be low. A consistent increase in the value of this measure is indicative of processing bottlenecks.

Certificate count

Indicates the number of certificates being managed by the Federated Authentication Service.



Certificate signing request

Indicates the rate at which the certificate signing requests were processed.


Ideally, the value of this measure shouldd be high. If this value dwindles with time, it is indicative of a processing bottleneck.

High load

These are estimates of the load that FAS can accept in terms of 'CSRs per minute'.


It is important to track the variations to the High load measure. This is because, if the the High load level is met, desktops and applications will fal to launch.

Medium Load

Low Load

Estimated load

Indicates the estimated load factor.


The values that this measure reports and the corresponding numeric values are listed in the table below:

Measure Value Numeric Value
Low 0
Medium 1
High 2

Exceeding the “High Load” threshold may result in session launches failing.


By default, this measure will report the Measure Values listed in the table above to indicate the estimated load factor. However, in the graph of this measure, the same will be indicated using the numeric equivalents only.
