• With Docker 1.8.0 shipped new log-driver for GELF via UDP, this means that the logs from Docker Container(s) can be shipped directly to the ELK stack for further analysis.
• This tutorial will illustrate how to use the GELF log-driver with Docker engine.
• Step 1: Setup ELK Stack:
  • docker run -d --name es elasticsearch
  • docker run -d --name logstash --link es:elasticsearch logstash -v /tmp/logstash.conf:/config-dir/logstash.conf logstash logstash -f /config-dir/logstash.conf
  • Note the config for Logstash can be found at this link
  • docker run --link es:elasticsearch -d kibana
• Once the ELK stack is up now let's fire up our nginx container which ships its logs to ELK stack.

• LOGSTASH_ADDRESS=$(docker inspect --format '{{ .NetworkSettings.IPAddress }}' logstash)
• `docker run -d --net=host --log-driver=gelf --log-opt gelf-address=u

This script is another demonstration of the update, enter, and exit selections in D3. The script also makes use of key functions to bind data to each row, and transitions to animate opacity and delay the removal of rows. This script demonstrates nested data, where an array of values is bounded to each row (<tr>), and then a single value is bound to each cell (<td>) element in the row.

Each row of the table has a unique letter key, which is displayed as the first cell. The remainder of the row is an array of random digits. At each iteration:

1. A new set of letter keys is randomly selected from the alphabet.
2. For each letter in the set, a new row with random data will be inserted in the table if the letter is not already in the table.
3. Any row in the table with a key which is not in the new set is removed.
4. The number of columns in the table is randomly adjusted. If the new number of columns is larger than the current table, random data is appended to each row. Otherwise, cel

Part 1

Proof of concept

Say, you want to save your D3 application in a CouchDB database. This is just a proof of concept that this is possible. I use the »Focus + Context« diagram by Mike Bostock (http://bl.ocks.org/1667367) as an example.

Prerequisites:

• A running CouchDB (see http://couchdb.apache.org/; in my Windows installation CouchDb is started as a Windows service when Windows starts).
• An installation of couchapp (how to install couchapp, see http://couchapp.org/page/index).
• Your favorite editor.
