From 7dc164bc5dd2068499eac6e3173454f97f09d9d5 Mon Sep 17 00:00:00 2001 From: gordon chung Date: Tue, 30 Dec 2014 16:26:44 -0500 Subject: [PATCH] add event pipeline this patch adds base framework for a new event pipeline manager to allow developers/operators ability to transform and trigger incoming notifications similar to how pipeline manager works for samples.
