     1  # Kata Containers Cassandra Metrics
     2  
     3  Kata Containers provides a series of read and write performance tests using Cassandra Stress tool.
     4  The Cassandra Stress tool is a Java-based stress testing utility for basic benchmarking
     5  and load testing a cluster. This tool helps us to populate a cluster and stress
     6  test CQL tables and queries. 
     7  This test is based in two operations, the first one is writing against the cluster or populating the database and
     8  the second one is reading the cluster that was populated by the writing test.
     9  
    10  ## Running the test
    11  
    12  Individual tests can be run by hand, for example:
    13  
    14  ```
    15  $ cd metrics/disk/cassandra_kubernetes
    16  $ ./cassandra.sh
    17  ```
    18  
    19  ## Expected results
    20  
    21  In order to obtain repeatable and stable results it is necessary to run the
    22  tests multiple times (at least 15 times to have standard deviation < 3%).
    23  
    24  # Kata Containers C-Ray Metrics
    25  
    26  This is a test of C-Ray which is a simple raytracer designed to test the
    27  floating-point CPU performance.
    28  
    29  ## Running the C-Ray test
    30  
    31  Individual test can be run by hand, for example:
    32  
    33  ```
    34  $ cd metrics/disk/c-ray
    35  $ ./cray.sh
    36  ```
