Scalability
This topic provides information about performance and scalability test results for PATROL for Amazon EC2 2.1.00.01.
Amazon EC2 KM can successfully monitor approximately 70 K CloudWatch metrics for a given AWS account using one PATROL Agent.
The following tables list the configuration that was used for running the performance and scalability tests.

Recommendations for monitoring the services in a large environment
- Use filters to exclude AWS regions that do not have any services to be monitored.
- Tune in the number of Java threads as per the javaOpts variable documented in the Configuration table.
