摘　　要：微机运行状态数据的提取是任务调度和资源有效利用的前提。基于JNI技术,结合VC++编程,实现了包括物理内存、虚拟内存及CPU等微机运行相关数据的提取,显示了直接提取的数据及简单处理过的内存使用率及CPU使用率。运行数据的成功提取,为网络化应用提供了以负载均衡为目标的指标依据。详细介绍了上述数据提取的具体实现,并通过实例证明了程序运行的有效性。　The microcomputer running status data real-time gain is the duty dispatch and the resources effective use premise. Based on JNI technology, mixed VC＋＋ with JAVA programming, realized to collect the microcomputer running data including physical memory, virtual memory and CPU, and then calculates both memory and CPU utilization ratio using JAVA. The performance data success gain may provide for the network application take the load equalization as the goal target basis. The implementation of data gain is also explained in detail, and furthermore, two examples are showed to prove the procedure movement is effective.
