Im::Alive

Post timestamps to a CouchDB database document. Useful for sending heartbeat signals or proving that an operation took place when it was supposed to.

The timestamp information that is written is:

{"timestamp" => "2015-02-01 00:00:00 UTC", "js_timestamp" => 1422748800}

CouchDB documents can be acessed through HTTP GET request, no special tooling is required to read the values back out, you can use Curl, do it from JS in a web page, from any programming language you can think of etc etc.

Installation

• weekly it the name of the document to write the timestamps to. The document is created if it doesn't exist.
