JVMモニタリング：PythonスクリプトJVMJMX取得状態



Jvm Monitoring Python Script Jvm Jmx Obtain State



主な原則：

主にPythonライブラリjmxqueryを介して、jmxquery JAVAメソッドは、JVM接続ポートを介してJARパッケージpythonスクリプト内でそれを呼び出し、JVMのステータスを取得します。



jmxquery github：

https://github.com/dgildeh/JMXQuery/tree/master/python



インストール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スクリプト：

JMXアドレスを指定するだけです。



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}') ## memoryPool type_str = 'MemoryPool' for name in ['Code Cache','Metaspace','Compressed Class Space','Par Eden Space','Par Survivor Space','PS Eden Space','PS Old Gen','PS Perm Gen','PS Survivor Space','CMS Old Gen','CMS Perm Gen','Perm Gen']: beanName_str = 'java.lang:type={0},name={1}'.format(type_str, name) jmxQuery = [ JMXQuery(mBeanName=beanName_str, attribute='Usage', 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}') Wherein the time unit is ## GarbageCollector s type_str = 'GarbageCollector' for name in ['Copy','MarkSweepCompact','PS Scavenge','ConcurrentMarkSweep','ParNew','PS MarkSweep']: beanName_str = 'java.lang:type={0},name={1}'.format(type_str, name) for atrributeName in ['CollectionTime','CollectionCount']: jmxQuery = [ JMXQuery(mBeanName=beanName_str, attribute=atrributeName, metric_name='Type:{type}_{attribute}')] metrics = jmxConnection.query(jmxQuery) for metric in metrics: print(f'{metric.to_query_string()} ({metric.value_type}) = {metric.value}') ## Threading jmxQuery = [ JMXQuery(mBeanName='java.lang:type=Threading', attribute='ThreadCount', metric_name='Type:{type}_{attribute}')] metrics = jmxConnection.query(jmxQuery) for metric in metrics: print(f'{metric.to_query_string()} ({metric.value_type}) = {metric.value}')
