real time internet monitor

We mentioned earlier that there are many Linux system monitoring tools that can be used to monitor system performance. However, we estimate that more users may prefer tools (top commands) that are included in most Linux distributions ). The top command is a real-time task manager in Linux. it is also used to find the system performance in the GNU/Linux release. W

forward better requirements, rsync in the high-end business system also gradually exposed a lot of shortcomings, first, rsync synchronization data, need to scan all files after the comparison, for differential transmission. If the number of files reaches millions or even tens of thousands of levels, scanning all the files will be very time consuming. And what is changing is often a small part of it, which is a very inefficient way. Second, rsync cann

I. Introduction of SERSYNC Project Project Address: http://code.google.com/p/sersync/ We often use Rsync+inotify to synchronize the server in real-time, where inotify is used to monitor file system events, and rsync is a widely used synchronization algorithm with the advantage of operating only the different parts of the file, So its advantage is much more than

Structured Cabling is now widely used in communications, finance, real estate, education, shipping, hotels, and other industries. As the cabling infrastructure continues to expand, management becomes increasingly complex. The most difficult issue for network administrators is updates to document records. Traditionally, wiring documents have been updated by hand, and it is not surprising that they are neglected. In addition, the burden and cost of netw

Due to the recent project needs, synchronization of cloud server data to the * * side to make big data analysis. Ideas: Initially, as long as the data is synchronized, prepare an Open data acquisition interface. But the real-time is poor, there will be delays. Therefore, the search for various solutions, finally determined to use rsync for file synchronization, otter (Ali's Open source tools) fo
