This test monitors the caching capability of the Forefront TMG and reports the following:

The rate at which the data is retrieved from the disk and memory that is allocated for content caching
• The rate of I/O operations that failed
• The rate at which URLs are stored and retrieved from the disk and the memory
• The ratio of memory cache to the overall cache

The default parameters associated with this test are as follows:

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

• In the HOST text box, the host name of the server for which the test is to be configured has to be specified.

• Specify the port at which the selected server listens in the PORT text box . By default, this is 1745.

• If the ISPASSIVE parameter is set to Yes, then it means that, by default, all the Forefront TMG servers being monitored by the eG system are the passive servers of a Forefront TMG cluster. No alerts will be generated if the servers are not running. Measures will be reported as “Not applicable” by the agent if the servers are not up.

• If multiple components of the same component type are awaiting configuration, then an APPLY TO OTHER COMPONENTS check box will appear in this page. Clicking on this check box 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.
