HONEYCOMB-293 - Memory benchmarking
Contains configuration for benchmarks: - Honeycomb on rest(just infra, no data) - Honeycomb with 1000 data nodes - Honeycomb with 10000 data nodes Each benchmark outputs two files: - out_path_name-HeapMemoryUsage.csv - out_path_name-NonHeapMemoryUsage.csv Both files are in format : committed,init,max,used 109576192,109051904,1525153792,12194752 Data sample sizes can be easily adjusted, just by changing start parameter -DsampleSize Change-Id: If6f9919307574237689326b4a38d410ec563200a Signed-off-by: Marek Gradzki <mgradzki@cisco.com> Signed-off-by: Jan Srnicek <jsrnicek@cisco.com>

+= management
+
+This modules is used to enable JMX monitoring on honeycomb Instance.
+
+= Tutorial
+== Configure
+To build honeycomb with management module incldued
+
+ mvn clean install -DskipTests -Pmanagement
+
+After this management module must be included to honeycomb module configuration.
+In /minimal-distribution/modules , just include fully qualified name of management module like so
+
+ io.fd.honeycomb.management.jmx.HoneycombManagementModule
+
+This will start all necessary beans to allow jmx connections to honeycomb instance.
+Also in logs , you will see all available JMX beans
+
+== Use
+
+To get any available JMX bean,
+use interface *JMXBeanProvider* that defines utility method to get *JMXConnector*
+
+ // get configured instance of jxm connection url according to HoneycombManagementConfig
+ @Inject JMXServiceUrl url;
+
+ // creates JMX connector
+ final JMXConnector connector = getConnector(url);
+ // to get any available bean
+ final String beanType = "java.lang:type=Memory";
+ final String beanName = "HeapMemoryUsage";
+ final Object jmxBean = getJMXAttribute(connector, beanType, beanName);
+
