Configuration of LtmDiskIOTest

This test auto-discovers the disks of the F5 traffic manager and reports how well the I/O operations were performed on each disk and in the process, identify delays in I/O operations. In addition, this test also reports the total amount of data transacted when performing read and write operations. This way, this test not only enables administrators to promptly detect current or probable latencies in I/O operations on each disk, but will also help them figure out which I/O activity was most latent - i.e., whether read operations or write operations?

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 IP address of the traffic manager has to be specified.

• In the PORT text box, enter the port number at which the traffic manager being monitored listens. By default, this is NULL.

• 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.
