Simple log-sharing utility built with Node.js, Redis and Cloudant.

npm install -g logshare

>tail -f /var/log/system.log | logshare
Share URL: https://logshare.mybluemix.net/share/kkdgapgdx

Put the URL in your browser and share it with the people you want to share your data with.

Alternatively, they can run logshare too to consume the data in their terminal like this:

> logshare https://logshare.mybluemix.net/share/kkdgapgdx

or

> logshare kkdgapgdx

to consume the stream of logs at their terminal.

Ctrl-C

When logshare is killed, it deletes the data you streamed to it.

Visit https://logshare.mybluemix.net for a live demo.

This is the server-side code for logshare. The client-side code lives in a separate repository.

Initiates a logshare session:

Returns a JSON object:

{"ok":true,"id":"dolpdpbld","shareurl":"https://logshare.mybluemix.net/share/dolpdpbld","channelname":"logshare_dolpdpbld"}

which includes the session id, the share URL and the Redis pubsub channel name.

Publishes a line of data to the logshare session identified by id. Expects a form-encoded body containing a single parameter body which contains the data to be published. Returns 200 on success or 404 if the id is not recognised.

Stops the logshare session identified by id. Stores meta data and prevents further data being published

Expects a message containing an id which is the id of the logshare session to subscribe to. If the session id exists, then the current WebSocket is associated with the that logshare id.

Expects a message containing an 'id' and a 'body'. If the logshare id exists, then data is written to Redis.

Removes the reference to the websocket.

If you want to deploy your own logshare server click the Deploy to Bluemix button below.

Don't have a Bluemix account? If you haven't already, you'll be prompted to sign up for a Bluemix account when you click the button. Sign up, verify your email address, then return here and click the the Deploy to Bluemix button again. Your new credentials let you deploy to the platform and also to code online with Bluemix and Git. If you have questions about working in Bluemix, find answers in the Bluemix Docs.

This project makes no guarantees as to the privacy of the data that you stream to logshare. If you are using https://logshare.mybluemix.net then the data is encrypted between the producer and server, and between the server and the consumers. There is no authentication mechanism to prevent an unknown third party observing your data stream, if they can guess the nine-digit session token. So don’t consider it safe for confidential data. It is designed to relay streaming data across development teams temporarily, not for anything you wouldn’t want others to see.

This project does not store your data at any time. Log data goes to a Redis pubsub channel and then relays immediately to any connected clients who have subscribed to that session. The data is then discarded, with only meta data about the session (the number of lines of data and the number of bytes of data received) being retained.
