JavaMelody v1.66.0 发布了。JavaMelody 能够监测Java或Java EE应用程序服务器，并以图表的方式显示：Java内存和Java CPU使用情况，用户Session数量，JDBC连接数，和http请求、sql请求、jsp页面与业务接口方法（EJB3、Spring、 Guice）的执行数量，平均执行时间，错误百分比等。图表可以按天，周，月，年或自定义时间段查看。

Charts of http/sql stats can not be viewed after restarting the application (with help from goldyliang).
In the collector server, malformed main html page when the monitored app is down.
In the collector server, spikes on gc, transaction and cpu graphs after collector restart.
In the collector server, after a restart, a monitored application can't be removed if it is no longer available.
When using the collector server, minor security issue if XML transport format with xstream is configured in the collector server parameters.
If the monitoring of an invalid JNDI datasource fails, don't ignore the others
When using Ehcache, display keys from the caches and add ability to remove a specific key from a cache
