Will do all wiki conversions and then commit the final version * Wiki links replaced by the link checker for test * Replacement work fine, but correct location for simple patterns has moved to libnetdata/simple_pattern * Corrected wiki links in READMEs, but most are in code files * More simple pattern link replacements * Want to merge current changes first and then continue with the link checker * Add checklinks.sh to validate links in MD files and fix them for both the repo and html static site * Minor link fixes, based on output from the linkchecker * About 50% done * Converted absolute links to relative * Close to being functional... * Getting closer... * Corrected edit files link from htmldoc branch to master * Replaced absolute links with relative and fixed incorrect heading hierarchy * Seems to be working.

Since [**netdata**](https://my-netdata.io/) refreshes this chart every single second, you may have unrealistic spikes is the size of the requests or responses is too big. The reason is simple: a response may have needed 1 minute to be completed, but all the bandwidth used during that minute for the specific response will be accounted at the second the log line is written.

67 When your system is under a DDoS attack, it will get a lot more bandwidth compared to the one it can handle and probably your applications will crash. Setting a limit on the inbound traffic using QoS, will protect your servers (throttle the requests) and depending on the size of the attack may allow your legitimate users to access the server, while the attack is taking place.

69 - Using QoS together with a [SYNPROXY](https://github.com/netdata/netdata/wiki/Monitoring-SYNPROXY) will provide a great degree of protection against most DDoS attacks. Actually when I wrote that article, a few folks tried to DDoS the netdata demo site to see in real-time the SYNPROXY operation. They did not do it right, but anyway a great deal of requests reached the netdata server. What saved netdata was QoS. The netdata demo server has QoS installed, so the requests were throttled and the server did not even reach the point of resource starvation. Read about it [here](https://github.com/netdata/netdata/wiki/Monitoring-SYNPROXY#a-note-for-ddos-testers).
