oren

system and process monitoring for clojure

At a time when I knew the least about my enemies,
the first name on my Death List, O-Ren Ishii, was
the easiest to find. But of course when one manages
the hard task of becoming queen of the Tokyo underworld,
one doesn't keep it a secret, does one?
 
- Beatrix Kiddo, Kill Bill

Overview

oren is a wrapper around the oshi project, a free JNA-based (native) operating system information library for Java. It is an alternative to sigmund and sigar for system information.

Installation

Add to project.clj dependencies:

[im.chit/oren "0.1.6"]

Usage

All functionality is contained within oren.core:

(require '[oren.core :as oren])
