javagent that pushes jmx counters to aws cloudwatch

A library to report jmx counters to cloudwatch for an arbitrary java process. Library is a javaagent that needs to be started together with the java process. It uses https://github.com/blacklocus/metrics-cloudwatch to push counters to cloudwatch

start the java process like

java -javaagent:cloudwatch-reporter-0.0.1-SNAPSHOT-jar-with-dependencies.jar -Daws.credentials.file={credentials} -Dbeans.file={beans} -Daws.instance={instanceId} -Daws.cloudwatch.endpoint={endpoint} -jar path-to-jar-file

{credential} is a path to a properties file with aws credentials as specified her: http://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/auth/PropertiesCredentials.html

{endpoint} is domain name of the endpoint url, could be monitoring.eu-west-1.amazonaws.com

{beans} is a path to textfile with beans names that should be pushed to cloudwatch. The format of a line is:

{beanName}.{attributeName} \t cloudwatch name

An example could be voldemort.client:type=ClientThreadPool.queuedRequests queuedRequests

{instanceId} is an identifier for the machine. Each counter will be submitted with a suffix like " instance={instanceId}*" so we can drill down on the individual instances. The '=' signifies a cloudwatch dimension

all beans registered through jmx will be pushed to stdout

mvn package
