Tailgate

Tailgate on Github: https://github.com/vimeo/tailgate

Tailgate is a nodejs app to pipe tail -F into websockets.

It’s a very simple way to have real-time access to your logs. It uses socket.io and coffeescript, and is great for keeping track of scribe logs.

Live demo here:

API

Tailgate exposes it’s feeds as a simple pub/sub api through socket.io connections making it easy to build visualizations or monitoring tools as simple web pages.

Installation

cd <install/directory> git clone git@github.com:vimeo/tailgate.git cd tailgate cp conf/conf-dist.sh conf/conf.sh 

Edit conf/conf.sh to have the correct values for your installation.

Optional

If you want to use the init.d.sh script.

cp startup/init.d-dist.sh startup/init.d.sh sudo ln -s <fullpath to tailgate/startup/init.d.sh> /etc/init.d/tailgate 

Edit the startup/init.d.sh script to use the installation directory and tailgate user to run as. Ensure the tailgate user has write permissions to startup/ so that it can write the pidfile.

sudo /etc/init.d/tailgate start sudo /etc/init.d/tailgate stop sudo /etc/init.d/tailgate restart 

Troubleshooting

• Make sure the HTTP port specified in conf/conf.sh is not already in use
• Enable logging in conf.sh by setting LOGGING="1"
