Configuration of CtxGwInCacheTest

The integrated cache provides in-memory storage on the Citrix Cloud Gateway Connector and serves Web content to users without requiring a round trip to an origin server. The cache monitors HTTP and SQL requests that flow through the target server and compares the requests with stored policies. Depending on the outcome, the integrated cache feature either searches the cache for the response or forwards the request to the origin server.

For best performance, majority of requests for web content should be serviced by the cache, without disturbing the origin server. If the cache is not sized right however, this might not be possible! To quickly detect irregularities in cache usage and sizing, administrators should know how much memory is used up by objects in cache, how much cache memory is free, and whether/not the cache is able to service requests efficiently with the memory available to it. This is exactly what the CtxGwInCacheTest!

This test monitors the requests to the cache, checks how well the cache processes the requests, and reveals whether cache misses are more than cache hits or vice versa. In the event that many requests are not serviced by the cache (i.e., if cache misses are more), administrators can use the memory usage statistics reported by this test to figure out if the cache is sized commensurate to its load.

The default parameters associated with this test are:

• The TEST PERIOD list box helps the user to decide how often this test needs to be executed.

• In the HOST text box, specify the HOST for which this test is to be configured.

• Specify the port number at which the specified host listens in the PORT text box. By default, this is 8443.

• To monitor a Citrix Cloud Gateway Connector, the eG agent should be configured with the credentials of a user with read-only privileges to the target connector. Specify the credentials of such a user in the USERNAME and PASSWORD text boxes.

• Confirm the password by retyping it in CONFIRM PASSWORD text box.

• By default, the SSL flag is set to No indicating that the eG agent will communicate with the connector via HTTP by default. If the target connector is SSL-enabled, then set this flag to Yes to enable the eG agent to communicate with target connector via HTTPS.

• If multiple components of the same component type are awaiting configuration, then an APPLY TO OTHER COMPONENTS button will appear in this page. Clicking on this button will allow you to apply the configuration to all/selected components of that type.

• Once the necessary values have been provided, clicking on the UPDATE button will register the changes made.

When changing the configuration for specific servers, a “*” beside the text box corresponding to the parameter signifies that these values have to be manually configured by the user. The parameter values that require to be configured will typically be prefixed with a “$” or contain a series of “*”. A value of “none” in the parameter value indicates that the corresponding parameter value can be changed if required.
