In parts 1th and 2nd of this series (a total of three articles), I introduced the techniques and patterns for monitoring Java applications, in which I focused on the JVM and application classes. In this final installment, I'll introduce tips for collecting performance and availability data from application dependencies, such as the underlying operating system, th

event listener, and the adapter class specifies which listeners the event should respond to . The adaptive class becomes an event listener, and the event source actually registers the adapter class as listener in the listener queue, and the actual event responder is not in the listener queue, and the action that the event responder should do is determined by the adaptation class . At present, most of the development tools in the generation of code, event processing is through the adaptation cla

unwilling to serialize some sensitive attributes and information, you can also call objectoutputstream. the writeobject () method explicitly specifies the attributes to be serialized. We will refer to custom serialization Methods later. ★BeanThe above serialization is only a basic application. After you serialize an object to an external file, use NotePad to open the file, you can only guess from a few readable characters that this is an information

In general, a Java background application, in the Linux terminal can start multiple, which causes waste of resources, and even the mutual operation of competing resources cause problems. The application is also launched using shell script, and there are some limitations in the shell script. You can skillfully avoid the problem of repetitive startup. For example,

In recent times, our production system upgrade frequently failure, the specific failure phenomenon is 10 minutes after the start of the transaction slow, processing thread exhaustion and so on, and the frequency of the failure occurs quite high. After detailed diagnosis and troubleshooting, we finally found the problem, which is that groovy runs in OSGi with ClassLoader deadlock, and finally we solve the problem.If it is difficult to find this problem by looking at the code alone, in this troubl
