Docker stats collection for collectd

This script can be used to feed collectd with cpu and memory usage statistics for running docker containers using the collectd exec plugin.

This script will report the used and cached memory as well as the user and system cpu usage by inspecting the appropriate cgroup stat file for each running container.

Usage

This script is intented to be executed by collectd on a host with running docker containers. To use, simply configure the exec plugin in collectd to execute the collectd-docker.sh script. You may need to adjust the script to match your particulars, such as the mount location for cgroup.

Rate limiting with Redis

June 2011 - Chris O'Hara - (archived original post)

Rate limiting can be an effective way of conserving resources and preventing automated or nefarious activities on your site.

A common use case is to limit the amount of requests an IP can make over a certain time frame. For example, you might want to restrict users from using an expensive search utility on your site. If the user attempts to search more than 5 times a minute, you can redirect them to another page informing them that they need to wait.

IP based rate limiting is already in use on larger sites. Google and Yahoo both employ the technique to prevent (or at least complicate) automated requests to their services.
