replica for each secondary replica, the contents of which are logs buffered from the log or capture from the disk, and the size of the queue reflects the difference between the primary replica and the secondary replica data being out of sync.Obviously, the two key factors that are most likely to affect AlwaysOn synchronization performance at this stage are the source of the capture log (disk or memory) and the size of the queue.In both of these facto

For some time, we have been on the internet to show readers how to configure a variety of different performance monitoring tools for Linux and Linux-like operating systems. In this article we will list a series of the most frequently used performance monitoring tools, and provide a corresponding introduction link to ea

Perfmon counters for the data flow engine in SQL Server integration services SSISWritten By: Jeremy KadlecProblemWe have adopted SQL Server 2005 Integration Services and we are moving a great deal of data on a consistent basis throughout the day for a number of systems. unfortunately, we have been seeing some memory related issues and wanted to find out how we cocould monitor these on a regular basis? We want someway to collect performance related dat

Today, more and more companies are starting to Docker, "two-thirds of companies have finally used it after trying out Docker", which means that the conversion rate of Docker is 67% and the length of the conversion is controlled within 60 days.Since Docker is so hot, is Docker surveillance supposed to be on the agenda? It may be specific, but it seems that everyone is looking for a new generation of Docker monitoring tools.This technology open class wi

The Visual VM also has a large advantage, which has a small impact on the actual performance of the application, making it possible to apply directly to the production environment.As for the specific how to use, it is not demonstrated, relatively simple. In addition to the above two tools, you can also use Jprofiler, Yourkit and other p

First, what are the key metrics to monitor for software performance testing? The main purpose of the software performance test is the following three points: 1. Evaluate the current performance of the system and determine if the system meets the expected performance requirements. 2. Look for possible

JoeZonkerBrockmeier mentioned five tools to monitor and improve Linux system performance in an article on the Linux Foundation website. These five tools cover kernel optimization, network monitoring, and system monitoring. they are KDESystemMonitor, Dstats, TheSysstatAuite, network monitoring using Ifstat, and Li Joe Z

A product requires stress testing, so I decided to use the performance tool provided by Windows2003 for system performance monitoring. If you have sufficient permissions in the test environment, you can easily use a dedicated machine to Execute Performance Tools and remotely monitor the target server, compared to execu
