Nmon (named Nigel's Monitor) is a computer performance system monitoring tool developed by IBM employees Nigel Griffiths for AIX and Linux systems. Nmon can display the operating system statistics on the screen or stored in a data file to help understand the use of computer resources, adjust direction and system bottlenecks. This system benchmark tool only needs to use one command to get a lot of important

There are many open-source network monitoring tools for Linux systems. For example, you can use command iftop to check bandwidth usage. Netstat is used to view the interface statistics report and the current running process of top monitoring system. But if you want to find a tool that can count network bandwidth utilization in real time, then Nethogs is worth a look.Nethogs is an open source command-line tool (similar to the

Sometimes our customers will find that the server or VPS network is slow, and further find that a lot of bandwidth is occupied, some customers so far do not know how to do. Is there a simple way to figure out which program (or process) is taking up the bandwidth? Linux monitors the flow of small tools, such as Iftop, Iptraf, Ifstat, Darkstat, Bwm-ng, Vnstat, and so on, mostly statistics and monitoring network card traffic. The nethogs introduced today

If the SVCTM is closer to await, stating that I/O has almost no waiting time, if the await is much larger than SVCTM, the I/O queue is too long, the response time of the application gets slower, and if the response time exceeds the allowable range of the user, consider replacing the faster disk and adjusting the kernel Elev Ator algorithm, optimize the application, or upgrade the CPU.The queue Length (AVGQU-SZ) can also be used as an indica
