How to use the Online reconfiguration of the Zorka monitoring platform, reconfiguration

On this page of Zorka: The http://zorka.io/install/basics.html introduces the basic functions of its Online reconfiguration, this feature allows you to reload the configuration file and plug in necessary files (reinstrument all classes that have been encoded or excluded from tracing) during the Application Server Runtime ). It seems that this function is quite powerful. Here we will only introduce the basic usage:

Disconnect, connect to the Apache process, and click MBean -- open the plus sign before Zorka -- ZorkaControl -- To the bottom directory. You can see two operations, one of which is "listTracerIncludes ", click the button on the right. Many pop-up windows are similar to: excl: 500: org. apache. juli. logging. */* (**) **, [a = 0x0001, f = 0x0809] results. The meaning is also quite clear.

Another operation is reload. When we add zorka. properties, We can click the button while tomcat is running to make the change take effect directly. Of course, Zorka also introduced: Note that reinstrumenting classes drains permgen on Sun JVM ....... It can also be imagined that, of course, JVM performance will be affected.

So much.
