Label:The IO performance of SQL Server is affected by the IO latency of the physical disk and the IO operations performed internally by SQL Server. When monitoring disk performance, the primary measure (metric) is IO latency, which is the time delay in creating an IO request from application to disk to complete the IO request. SQL Server is prone to

In parts 1th and 2nd of this series (a total of three articles), I introduced the techniques and patterns for monitoring Java applications, in which I focused on the JVM and application classes. In this final installment, I'll introduce tips for collecting performance and availability data from application dependencies, such as the underlying operating system, the network, or the application's back-end data

Then we manage the server when the WINDOSW system is more intuitive, how much CPU use, how much bandwidth memory used, etc. as long as in the Remote Desktop Task Manager at a glance. But in the Linux environment is not so easy, especially the server or VPS running is a large web site, if you can not find the server performance consumption in time, it is likely to lead to the site in the peak visit, there is no known card death. So, eagle, then. This a
