ALEC 2.1.2-alpha

Release 2.1 Description and Notes
ALEC 2.1 improves the visualization of situations and the alarms affecting them by:

• New GUI - We have re-designed the way we show situations under OpenNMS Horizon new graphical User Interface. This will help you identify active situations, the complexity and severity of them, and how alarms relate to each other.
• Situation Timeline - We help you visualize at what time the alarms that contribute to a situation started, supporting your efforts at determining the root cause of a situation.
• Accept or Reject a Situation - You now have the opportunity to Accept a situation, and most importantly Reject the situation. Upon Rejecting it you won't be bothered by it anymore, and it will give you an opportunity to help the OpenNMS product (more on this below).

In addition, it incrementally improves on the DBSCAN alarm correlation engine by allowing you to select the Hellinger Distance as a mechanism to detect what alarms may be related to each other.

Most importantly, with your voluntary help, we will be able to capture information about the situations that you believe are correct and the ones that we have mis-identified. This will help us bring you a future version of the product that is more accurate at detecting situations.

Situation - A situation is a group of alarms that we suspect are related to each other and are a consequence of the same root cause. By grouping them together we support you in quickly identifying the source of the problem, addressing them, and as such reducing the complexities and noise resulting from a large number of alarms.
