Due to a failure in TSC synchronization,toputility does not show CPU usage properly in the RHEL7. The issue was identified in some Dell servers. 诊断步骤 Aftertophad been running for around 1 minute while high intensive CPU operations were being executed, all processes showed no CPU usage. Y...
jmx,如果开启了jmx,则我们可以直接通过jvisualvm查看内存,线程监控情况,还可以查看其他jmx指标; 从这里你可以,看到内存的变化趋势,垃圾回收,cpu变化趋势等等,很多直观的问题完全可以在这一环节发现。另外,你可以通过采集cpu和采集内存的方式,发现代码中的瓶颈点。可以说,jmx是我们进行代码优化或者参数调优的绝对王者工具。
