Monitoring and recording ground server process/port usage Bandwidth traffic

Due to the company's troubleshooting needs, it is necessary to record and save the high bandwidth-consuming processes or ports on the public server, so that you can check the problem later.

This problem tangled 1, 2 days, the use of Python should be able to meet the needs, but the novice python is not to take the shot, so can only rely on the Linux finished gadgets and Shell to achieve.

Linux iftop and nethogs two tools to meet the requirements, but neither of these tools are perfect to record the content, if the use of redirection to record content, then the recorded things are not text format, using Cat view is not a problem, but want to edit or filter, It's not going to work, so be interested to try it yourself.

Later colleagues found a new version of Iftop, Iftop-1.0pre3 (http://freecode.com/projects/iftop), may need to turn over the wall to access, and install iftop-1.0pre3 need to install some dependencies, yum and Apt-get have no way to get to, can only go to search compiled by themselves, relying on the installation is too complicated, you find it by yourself search.

After the iftop-1.0pre3 is installed, the content can be printed to the screen using the-t parameter, and the redirection is able to output the content normally.

Leaders anxious to script, so no content optimization, and do not use SQL for content storage, later time can be optimized or improved, making it easier to query retrieval, here is a record.
