A JConsole chart with 30 threads
With a different number of threads it is clear that parameters can vary in terms of
resource utilization and performance. It is advisable to use stress tests to monitor the
system's limit based on the application's SLA.
Read Mode
With read mode, let's test the Cassandra server for with a heavy read-only operation.
Here we will perform a stress test over the Cassandra server to monitor its performance
with various parameters.
The simplest command to start a read stress test is
$CASSANDRA_HOME/tools/bin/cassandra-stress -o read
Figure 8-7
shows the result.
