At times, we want to know the performance of our database queries under load.  These type of load tests would rarely be tested from locations outside your infrastructure.  Opening holes directly to a database in the open would be a poor security model.

Redline13 JMeter Load Testing allows you to easily deploy JMeter load plans inside your AWS domain and hammer away with your queries. 

In this load test, we started a MySQL instance creating a table called countries, which we sourced from this country data source.

Our Load Plan is to launch 5 servers each starting 200 users iterating 50 times and ramping over 5 minutes.   That would give us 50,000 queries over a few minutes. 

1. We add a JDBC Configuration, selecting information for our Mysql/JDBC setup.
   • 
2. Add a JDBC Request to make our query
   • 
3. Building our Redline13 Load Plan 
   1. Drop in your JMX File
   2. Drop in your JAR file for the DB connection library
      • In our case, we are using MYSQL 
      • 
   3. Select your instance Types and Configure Subnet ID if appropriate
      • 
4. Run your test! 
   1. Oops, we had plenty of success calls but we did find an issue.  Our database instance has limited total connections and we can see that in our error section. 
      • 
   2. We changed our configuration and ran our test again.
5. Sample Output
   • 

The results and copy of the test are available on the results page.
