Simulate Distributed Lucene with Persistence Cache Usage

To simulate the usage of your created cache, NCache provides the Test Stress option. The Test Stress mechanism simulates a heavy transactional load on your Distributed Lucene cache(s). You can then view Distributed Lucene with Persistence counters provided by NCache either through NCache Statistics or PerfMon tool.

Test Stress Through NCache Management Center

Follow the steps mentioned below to simulate your cache usage under stress through the NCache Management Center:

• Launch NCache Management Center by browsing http://localhost:8251 or <server-ip>:8251 For Windows and Linux.

• From the left navigation bar, click on Clustered Caches.

• Select your cache and click on .

• Once the Test-Stress button is clicked, you will be prompted with a dropdown menu where you will have to specify the time for the test stress. After selecting the time, click on the start button.

View Simulation Through NCache Statistics

• Go to the statistics page by clicking against your selected cache in the NCache Management Center.

• You can view that the data is being added to the cache through the Distributed Lucene counters shown on the screen. After the set expiration interval has elapsed, the counters will show data being removed from the cache.

Test Stress through NCache PowerShell Cmdlet

You can quickly test the performance of the cache under stress using the Test-Stress cmdlet. This command generates a heavy transactional load on a specified cache by feeding it sample data automatically. The following example demonstrates how to use the Test-Stress command in the PowerShell:

Test-Stress –CacheName demoClusteredCache

This command starts making cache calls to the cache servers as Test-Stress simulates a transactional load on the specified cache.
