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

Joe Zonker Brockmeier 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 KDE System Monitor, Dstats, The Sysstat Auite, Ifstat network

If you are unfamiliar with the six open-source system monitoring tools, you are advised to refer to the relevant technical documents.1. Nagiox-network monitoring software Nagios is well-known and undoubtedly the best system monitoring tool. As you know, most O M teams use this tool, and so far, no tool exceeded it. Ho

which the RAM segment can be moved to a special disk segment of swap disk, where the page export and page import of virtual memory occur, and page export does not indicate a ram bottleneck. The virtual memory system often makes page exports to the memory segment, but the page import operation indicates that the server needs more memory, and the page import needs to copy the memory segment from swap disk back to RAM, causing the

not indicate a ram bottleneck. The virtual memory system often makes page exports to the memory segment, but the page import operation indicates that the server needs more memory, and the page import needs to copy the memory segment from swap disk back to RAM, causing the server to become slower.There are several ways to solve this problem:1. The simplest, increase the RAM;2. Reduce the need for RAM by cha

Tools for batch monitoring MySQL db layers in Linux are relatively scarce, and SSIS is used for DIY. Use the SSIS package to read the configuration table information to monitor MySQL and send feedback to DBA by email according to the actual situation. 1. sort out a global information table, including ip addresses and monitoring dimensions. The table creation sta

Linux performance analysis sar command explanation SAR (system activity Reporter System Activity Report) is currently one of the most comprehensive system performance analysis tools in Linux. It can report system activities from multiple parties, including: file read/write, system call usage, disk I/O, CPU efficiency, memory usage, process activity and IPC-related activities. Common sar command formats SAR [Options] [-A] [-o file] T [N] Where: T indic
