Simulate NCache with Test Stress to Monitor Cache Performance

To simulate the usage of your created caches, NCache provides the Test Stress option. The Test Stress mechanism simulates a heavy transactional load on your specified caches.

Note

This feature is also available in NCache Professional.

Note

You can simulate the usage of different store types and monitor Cache Counters for your cache by following the same steps listed below.

Test Stress Through the NCache Management Center to Monitor Cache Performance

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

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

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

• Create a new cache or select the cache you want to simulate.

• Make sure that the cache is started.

• On the toolbar, click on the Test-Stress button, which opens up a dialogue box containing various time options.

• From the options list, you can select how much time you want the Test-Stress to run. The options are:

  • 10 seconds
  • 30 seconds
  • 1 minute
  • 3 minutes
  • 5 minutes

• This is the time for which the data keeps on adding to your cache, and after this specific expiration time has elapsed, the data will be removed from the cache.

• To see how these cache counters are updating, you have two options. Either click on the Monitor option on the toolbar and visualize the cache counters or the Statistics option to monitor the stats of your particular cache.

• Following are the details provided for both the above options.

View Simulation Through the NCache Monitor

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

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

• 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 the data being added in the cache through the counters displayed on the NCache 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 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 view the statistics for different operations on the cache like Additions/sec and Fetches/sec.

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