Simulate NCache with Test Stress

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

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

Test Stress Through the NCache Manager

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

Launch the NCache Manager by browsing http://localhost:8251 or <server-ip>:8251 on Windows and Linux.
From the left navigation bar, click on Clustered Caches.

NCache Web Manager 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.

NCache Monitor through Test Stress Options

From the options list, you can select for 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:
