is a dashboard that aggregates information about the environments of a project.
This includes data such as which applications exist in the environments,
what versions are deployed, what databases are used, how to access log files, etc.
ESP collects the data by querying the environments themselves to ensure it is fresh and accurate.
Why would I use it?
In a typical software project its not uncommon to have multiple environments: QA, performance,
staging, production and such. There are also multiple people interested knowing the status of
the environments - devs, testers, analysts and others. Usually this information is available to devs
and sysadmins, and so they have to look it up for everyone else. As the number of
environments and people grows, it starts taking too much of everyone's time to continously go
through devs and sysadmins. So ESP aims to alleviate this problem by providing a single central
location to find all information about environments and allow people to do their own monitoring.
How does it work?
Given that environments vary enormously from project to
project, ESP can't just work out of box for most projects. Collecting the environment data
requires significant customization. Rather than build some evil custom configuration tool that
is painful to use and doesn't do what you want anyway, we decided to provide an incredibly
sexy and powerful tool you already know - Ruby. To customize you just write ruby code. As
the project progresses we aim to provide some standard customizations like Websphere, but
until that point we provide some examples for you to work off of.
There is nothing limiting you to just passively displaying data with ESP. It can also be
the access point from which to administer your environments and deploy new versions of
