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.

Minimalist static FFmpeg build on Ubuntu 16.04 with Nvidia NVENC enabled.

Original guide with a standard build is here.

With this guide, I'm adding more instructions to enable support for NVIDIA CUVID and NVIDIA NPP for enhanced encode and decode performance.

First, prepare for the build and create the work space directory:

cd ~/

NVIDIA driver 375.66

Install Microsoft Office 2010 on Ubuntu

Requirements

We'll install MSOffice using the PlayOnLinux wizard. Additionally, MSOffice requires samba and winbind to properly work.

So, if not installed, install them:

sudo apt-get install playonlinux samba winbind

	# This is the simplest definition, with the addition of a type
	input {
	udp {
	port => 25826 # Must be specified. 25826 is the default for collectd
	buffer_size => 1452 # Should be specified. 1452 is the default for recent versions of collectd
	codec => collectd { } # This will invoke the default options for the codec
	type => "collectd"
	}
	}

	Basic Requirements:

	Computer with wired and wireless connection
	FFmpeg installation: http://www.ffmpeg.org/
	GoPro Hero 3+: http://gopro.com/
	RTMP server e.g. FMS (http://www.adobe.com/products/adobe-media-server-family.html) or CDN ingest point

	Overview:

	GoPro Hero3 cameras produce HLS streams which are consumed by control apps and their removeable monitor.

	I have run an nginx container...

	docker ps
	CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
	6d67de07731d nginx "nginx -g 'daemon ..." 40 minutes ago Up 40 minutes 80/tcp, 443/tcp epic_goldberg

	I want to use Debian for debug:
	docker run -it --pid=container:6d67de07731d --net=container:6d67de07731d --cap-add sys_admin debian
