If a service is deployed on dozens of machines, we usually need to spend a lot of time every day to check the running status of the service on each machine, although Microsoft has Microsoft's mom (Microsoft Operations Manager) and SMS (Systems Management Server), we are still unable to use these things for cost and other considerations, in fact, Microsoft has published many management and monitoring APIs an
the Nigel's Monitor. this popular open-source tool is used to Monitor the performance of Linux systems. Nmon can monitor the performance information of multiple subsystems, such as processor usage, memory usage, running queue information, disk input/output statistics, network input/output statistics, memory paging activity, and process metrics. Then, you can view the real-time system measurement result of nmon through the "graphical" interface of curses.
To run nmon, you can start the tool from
no read and write operations, whereby the administrator can be in the server's disk to balance the deployment of related services software to reduce the read and write of a partition, request pressure to improve server disk performance. The Physical disk activity feature is similar to the above, except that it monitors the health of the server from the point of

, once an SNMPAgent is deployed on a common server, any software that can implement the SNMP protocol can monitor it, in addition, the user name and password of the monitored server are not required for monitoring through this method, so it is safer. The disadvantage is that many servers do not install SNMPAgent by def

Tcpdump is a simple and reliable network monitoring utility. Its basic protocol analysis allows you to make a cursory view of the situation on the network. But to really delve into the network, you should use Wireshark (described below).
