A Ruby client for Hawkular

A simple way to check your app heart.

This gem is designed for use by Rails applications running on Heroku. For others, the better approach is to use a frontend server such as nginx or Apache. However, the Heroku Cedar stack is no longer fronted by a file server, and there is no automatic provision for gzipping responses. This gem activates Rack::Deflate for all requests. In addition, we serve up the gzipped versions of our precompiled assets, taking advantage of the higher compression ratio used during precompilation, and reducing CPU load at request time.

Rack middleware ensuring at most once requests for mutating endpoints.

OKF (Open Knowledge Format) is portable knowledge: Markdown files with YAML frontmatter that both humans and agents read from one source. This gem is the Ruby-native way to work with it. Its companion agent skill authors and curates a bundle. The `okf` command-line tool validates the result for v0.1 (§9) conformance, lints its curation quality, and answers questions about it: ranked full-text search, and a progressive-disclosure map that reads a large bundle a directory at a time rather than loading it whole. `okf server` opens it as an interactive knowledge graph and `okf render` bakes that same page into one self-contained HTML file you can host anywhere. A per-user registry names your bundles, so every verb reaches them by @slug from any directory and one search can span them all. Everything the CLI does also runs in-process through a library API (OKF::Bundle and friends), and the graph server is a mountable Rack app. It adds no service to your stack: rack, webrick and minifts are the only runtime dependencies, and it runs on every Ruby since 2.4.
