performance profiling tools

solve these problems. PTA works to diagnose the causes of Exchange server performance problems. Similar to Performance Monitor, PTA needs to occupy some system resources, which causes the performance of servers that lack system resources to decline further. However, we must remember that the PTA tool is designed to use the least effort to find the root cause of

For every system administrator or network administrator, it is very difficult to monitor and debug Linux system performance issues every day. I've had 5 years of experience working with Linux administrators and know how to monitor the system to keep it running properly. To do this, we have written 20 command-line system monitoring tools that are useful and most commonly used by Linux/unix system administrat

What skills Modern network performance monitoring tools should have. Previously, enterprise network engineers had to provide network access and sufficient bandwidth for a variety of connected servers, applications, and end devices. From the OSI model perspective, these tools focus primarily on 1-4 layer networks. Because all traffic and data flows across a networ

Although. The NET Framework claims to never have a memory leak because of the introduction of a memory-recycling mechanism. In practice, however, we often assign objects without releasing a reference to the object, causing the object to never be freed. The most common scenario is to add an event handler to an object, but it is not removed from the object's event handler when the object is no longer being used. In addition, if you allocate unmanaged memory without manually releasing it, the GC is

Common performance analysis tools. 1. vmstat commandVmstat is short for Virtual Meomory Statistics (Virtual Memory Statistics). This command tool is installed by default in many linux releases, the vmstat command can be used to monitor the memory information, Process status, and CPU activity of the operating system. The disadvantage is that a process cannot be deeply analyzed.The vmstat syntax is as follows

development. Again, we are glad that Microsoft has provided the. NET memory debugging tool for the mobile phone: Power toys for. NET Compact framework. For the general usage, see here.With power toys, we can easily see which memory leakage occurs. For example, if a problem occurs, it is easy to know that bitmap is not immediately dispose after being created. At the same time, because the Delta value per second is constant to 2, it can be inferred that it is related to an interval> = 500ms timer

errors, bottlenecks and abnormal activity5:arpwatch– Ethernet Activity MonitorThe Arpwatch is designed to monitor Ethernet address resolution (changes in Mac and IP addresses) on Linux. He continuously monitors Ethernet activity for a period of time and outputs a log of changes in IP and MAC address pairs. It can also send an email notification to an administrator, alerting you to an increase in address pairing. This is useful for detecting ARP attacks on a network.For more information, see: Ar

There are many Oracle Performance Tools. I accidentally saw Metalink Note (438452.1): Performance Tools Quick Reference Guide mentioned in Tanel Poder on a website. This document is indeed quite new, and there are several tools worth noting. LTOM：TheLiteOnboardMonitor

While not every Python program you write requires a rigorous performance analysis, it is reassuring that the Python ecosystem has a wide variety of tools to deal with problems when they occur. The performance of the analyzer can be summed up to answer four basic questions: How fast it is running Where is the speed bottleneck? What is the memory usag

Website loading speed is the most important factor to determine the level of the site, worthy of special attention of stationmaster. The reason is simple, no one wants to open a Web page and so on long time, in other words, if your site is very slow to open, will churn out a large number of visitors, and even the effects of the multi-meter effect of the adverse effect. Before you dive into the code to try to improve your site's speed, determine what the real cause of the slow site access is. Thi
