Many corporate LANs now have their own file servers for storing or sharing files for use by local area network users. However, in the process of setting up shared file access, it is common for shared files to be randomly copied, modified, or even deleted, which makes the security management of shared files face a greater risk. How can you make it possible for users to access shared files and prevent improper operation of shared files? I think that can be achieved through the following two ways:

Cacti is an open-source network monitoring tool that monitors the status and load of hosts, it can be used to monitor the running status of servers such as Apache and MySQL.

When the server is doing the testing, it needs to monitor the network traffic to understand the network usage of the server at different numbers of times.We use the server environment is centos7,centos under the general use of iftop, or nethogs for network traffic monitoring. All 2 tools need to install Epel first, because this library usually does not own the operating system.Then install Epel First, using the following commands:RPM-UVH https://dl.fe

There are a lot of performance tools on the Linux platform, a dazzling, long-term groping and experience finding the best thing to use is the proven, simple gadgets. Brendan D. Gregg, a system performance expert, updated his famous talk (Linux performance Tools) and slides on Linux in the recent LinuxCon NA 2014 conference. Compared with Brendan last year's talk, this year added testing and optimization to the two parts. The three images below summarize each subsystem of Linux and the tools used
