Simulate Cache Usage

To simulate the usage of your created cache, NCache provides the Test Stress option. The Test Stress mechanism simulates heavy transactional load under stress on the cache that you specified.

Test Stress Through NCache Web Manager

Follow the steps mentioned below to simulate your cache usage under stress through NCache Web Manager:

  • Launch NCache Web manager by browsing http:localhost:8251 (Windows) or <server-ip>:8251 (Windows+Linux).

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

  • Select the cache you want to simulate and click on the ... button against it. This will open up a dropdown menu of various operations that you can perform on a cluster.

  • From these options, select Monitor Cluster if you want to visually see the counters updating, or select Show Statistics if you want to view the stats of the cache you want to simulate.

View Simulation Through NCache Web Monitor

NCache Web Monitor provides a graphical view dashboard to monitor various cache counters. If you choose to view cache usage simulation through NCache Web Monitor, follow these steps:

NCache Web Monitor

  • Click on the Test-Stress button. This will open up a dialog box through which you can customize your simulation.

NCache Simulate Test Stress Data

  • In the dialogue box, you can choose the Test-Stress timer for 10 or 30 seconds or 1, 3 or 5 minutes, depending on your choice.

  • As soon as you press the Start button, you can visualize the various cache operations that take place on the client dashboard.

  • You can view that the data is being added in the cache through the counters displayed on NCache Web Monitor. After the set expiration interval has elapsed, the counters will show data being removed from the cache.

View Simulation Through NCache Statistics

NCache Statistics provides a report view of various cache counters. If you choose to simulate cache usage through statistics, then follow these steps:

  • On the statistics board, click on the Test-Stress button. This opens up a dialog box through which you can customize your simulation.

  • In the dialogue box, you can choose the Tess-Stress timer for 10 or 30 seconds or 1, 3, or 5 minutes, depending on your choice.

  • As soon as you press the Start button, you can view the statistics for different operations on the cache like Additions/sec and Fetches/sec.

  • You can view that the data is being added in the cache through the counters shown on 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 run a Stress Test Tool that comes with NCache installation to verify that cache clients can make calls to cache servers.

To start this test on the cache you just created, please type the following command in Windows PowerShell:

Test-Stress –CacheName ClusteredCache

This command starts making cache calls to the cache servers as Test-Stress simulates transactional load on the specified cache. You can monitor the cache performance using PerfMon counters and NCache Monitor.
