aix performance monitoring tools

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. Becau

Linux performance monitoring and analysis tool background recently, a pre-developed system performance test is required. The system is deployed on the Linux server cluster. In high concurrency and high load scenarios, you can collect all the information (including CPU, memory, I/O, disk, and network traffic) occupied by each device... linux

Unix system performance monitoring tools-SAR System Environment: Operating System: AIX 5.3.9 Oracle: Oracle 10gR2 SAR can be used to monitor Unix system performance and help us analyze performance bottlenecks. The sar tool is used

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

handling, and performance analysis capabilities, and is very powerful. 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, yo

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

When there is a problem with the Linux system, we not only need to look at the system log information, but also use a lot of performance monitoring tools to determine what part (memory, CPU, hard disk ...). ) out of the question. In the Linux system, all the operating parameters are saved in the virtual directory/proc, in other words, we use the

Monitoring Linux system performance every day is a daunting task for every system/network administrator. After 5 years of Linux system administrators in the IT industry, I found it's not easy to monitor and keep the system up and running, so I've summed up 8 very useful command-line tools for Linux/unix system administrators. These commands support all Linux syst

For system and network administrators, it is a heavy task to monitor and debug the performance of Linux systems on a daily basis. After 5 years working as an administrator in the IT field as a Linux system, I gradually realized how difficult it was to monitor and keep the system up and running. For this reason, we have written a list of the 18 most commonly used command-line tools that will help each Linux/

Overview When the system bugs need to locate the problem, knowledge, experience is the key foundation, the data is the basis, the tool is the use of knowledge processing data means. The data mentioned here include: Run log, exception stack, GC log, thread snapshot (threaddump/javacore file), heap dump Snapshot (heapdump/hprof file), etc. Using the appropriate virtual machine monitoring and analysis tools c
