Guidelines to help you understand some of the basics of monitoring and measuring performance issues in the WebSphere Portal environment
To optimize the WebSphere Portal environment for optimal performance, you need to know what needs to be optimized. The monitoring methods discussed in this article cover several impor
value is less than 5m, SQL Server may have a performance bottleneck due to lack of memory. 4.Physical Disk:% Disk Time This counter records how busy the disk is (the entire disk array or the physical disk is busy). Theoretically this value should be less than 55%, if it lasts more than 55%, that indicates that there may be an IO bottleneck on this server. If only occasionally appear several times, that does not need to worry, but can correspond to fi
When the system's physical memory is insufficient, a portion of the physical memory needs to be released for use by the currently running program. The allocation of Swap space is important, but the performance monitoring during system operation is more valuable. Through performance monitoring tools, you can check the
What can jwebap bring? Jwebap is a component used to monitor the performance of J2EE projects (EJB and webmodule systems). It has the following features:
1) Static Enhancement Based on ASM implementation class, which can be seamlessly deployed in the J2EE system, and the overhead of the system can be almost ignored
2) deployment and use are very simple. For jwebap deployment, you only need to deploy jwebap_core _**. jar and various plugin _**. jar, an
