Java JMX get the logged in user

由 孤人 提交于 2020-01-04 11:05:46

For example as an option I looked at official tutorial and its ok for now to use user/password authentication. The MBeans are deployed via spring (annotations approach is used). Now I would like to get from within my MBean the user name for some additional actions. Is it possible to do in JMX technology at all? If Yes how? :) Example: public class

How to find the C.P.U load (percentage of C.P.U utilization) in the slave node

由 不羁岁月 提交于 2020-01-03 05:56:10
问题 Hi am developing a load balancing algorithm in java. In my system there will be one mater node and list of slave nodes, Where the master node will distribute the incoming request to one of its slave node. I want to find the C.P.U load (percentage of C.P.U utilized) in each of the slave nodes. So that the master node can effectively distribute the request to one of its least loaded slave node. Can any one please suggest me how can we find it. The getSystemLoadAverage() method in JMX can be
