Monitor NCache with Test Stress

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.

NCache Web Manager Clustered Caches

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

Note

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 option 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 in 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.
