1. Overview Monitoring is an indispensable part in checking system problems or optimizing system performance. The operating system monitoring tool monitors the usage of operating system resources and indirectly reflects the running status of each server program. The analysis based on the running results can help us quickly locate the scope of system problems or
Network monitoring is the most complex in all Linux subsystems, with too many factors, such as latency, blocking, conflict, and packet loss, even worse, the routers, switches, and wireless signals connected to Linux hosts all affect the overall network and it is difficult to judge whether the problem is caused by the Linux network subsystem or other devices, monitoring and network judgment are the most comp

Because Nagios is too complex, the previous Zabbix has emerged as a condition of knowledge. I just want to find a tool that can collect data for analysis in real time, glances is undoubtedly the best choice.In addition, when I was looking for tools, I found a relatively good simple monitoring tool--linux dashboard.

host is negligible because the customer is responsible for tracking status, sampling rate, and calculation.In addition, metrics are not aggregated across hosts or remain unchanged outside the user's browser session, keeping the framework clear. vector only requires the local browser and PCP installed on the host you wish to monitor. An intermediate collector, server, or database infrastructure is not required.The final monitoring page looks like this
disk partition. But be careful, the cost of using swap is very high. If the system does not have physical memory available, it will be frequently swapping, if the swap device and the program is about to access the data on the same file system, it will encounter serious IO problems, eventually causing the whole system to slow down, or even crash. The swapping state between swap devices and memory is an important reference for determining the performance
