As an Adminstrator, I want to view all cluster-split and cluster-merge events in the last 7 days. Each event should indicate the following information: time-stamp of event, Merge/Split, the cluster View before Merge/Split, the cluster View after Merge/Split.

Cluster events will be visualized as a summary in the cache containers page
https://rawgit.com/infinispan/infinispan-console-mockup/master/cache-containers.html

and in the cluster list page
https://rawgit.com/infinispan/infinispan-console-mockup/master/clusters.html

A detailed ‘Grid events’ page will be added:
https://rawgit.com/infinispan/infinispan-console-mockup/master/events.html

Type of logs:

• Task execution (as requested by users)
• Node join/leave
• Split/Merge
• Rebalancing start / stop
• Mass indexer
• Server start/shutdown
• Site up / down
• Cache related events

Log properties:

• Timestamp
• Title
• Description

Logs will be of severity INFO and ERROR.
Logs will be stored in a persistent, eviction, 7 days expiration cache.
