You can change the JMX configuration by editing the jmx.xml file in the <ML_HOME>/repository/conf/etc directory. You can configure JMX ports, RMIRegistryPort and RMIServerPort from the Ports section of the <ML_HOME>/repository/conf/carbon.xml file.
MBeans exposed in WSO2 ML
A few MBeans are exposed in WSO2 ML, to monitor key statistics such as dataset summary generation times, model building times, prediction times, thread pool params etc as described below.
| MBean name | Description | Attributes |
|---|---|---|
org.wso2.carbon.ml.thread-pool-active-count | Active threads in the WSO2 ML thread pool | value |
org.wso2.carbon.ml.thread-pool-queue-size | Size of the queue used by the WSO2 ML thread pool | value |
org.wso2.carbon.ml.dataset-summary-generation-time | Descriptive statistics on the time spent on generating summary statistics of datasets uploaded to WSO2 ML (in milliseconds). | count, min, max, mean, standard deviation etc. |
org.wso2.carbon.ml.model-building-time.<ALGORITHM_NAME> | Descriptive statistics on the time spent on model generation based on a ML algorithm (in milliseconds). | count, min, max, mean, standard deviation etc. |
org.wso2.carbon.ml.prediction-time.<ALGORITHM_NAME> | Descriptive statistics on the time spent on prediction from a model generated by a ML algorithm. (milliseconds) | count, min, max, mean, standard deviation etc. |
You can view the above MBeans using JConsole or an equivalent tool which is capable of monitoring JMX MBeans as shown in the examples below.
Dataset summary generation time MBean
