python脚本JMX获取JVM状态

python脚本JMX获取JVM状态

主要原理： 主要通过python库jmxquery，jmxquery是通过python脚本调用它里面的JAR包的JAVA方法连接JMX端口，以获取JVM的状态。 jmxquery github：安装jmxquery： $ pip install jmxquery Collecting jmxquery Downloading https://files.pythonhosted.org/packages/93/02/b079e4df07f4c23bc5759742c488673008327dcd14713b519a96c7cc3e94/jmxquery-0.5.0.tar.gz Installing collected packages: jmxquery Running setup.py install for jmxquery: started Running setup.py install for jmxquery: finished with status 'done' Successfully installed jmxquery-0.5.0 You are using pip version 19.0.3, however version 19.2.3 is available. You should consider upgrading via the 'python -m pip install --upgrade pip' command. PYTHON脚本： 只要指定JMX地址即可。 from jmxquery import JMXConnection, JMXQuery jmxConnection = JMXConnection("service:jmx:rmi:///jndi/rmi://127.0.0.1:8889/jmxrmi") ## memory type_str = "Memory" beanName_str = "java.lang:type={0}".format(type_str) for atrributeName in ["HeapMemoryUsage","NonHeapMemoryUsage"]: jmxQuery = [ JMXQuery(mBeanName=beanName_str, attribute=atrributeName, metric_name="Type:{type}_{attribute}_{attributeKey}")] metrics = jmxConnection.query(jmxQuery) for metric in metrics: print(f"{metric.to_query_string()} ({metric.value_type}) = {metric.value}") ##
