Hi, skyline is a great work, here is my views:<p>1. Skyline has many built-in detection algorithms. Banshee only uses the 3-sigma rule.<p>2. Skyline&#x27;s algorithms are pure and simple, without considerations of burr points, scatters (like counters).<p>3. Banshee comes with alerting rules management panel. Skyline&#x27;s webapp is a simple analyzation results viewer.<p>4. Banshee uses the anomaly-factor trending (via weighted moving average) and skyline doesn&#x27;t. The trending follows the analyzed score (which is to describe how anomalous the current metric is), thus, alerts only happen if the metric is anomalous enough (i.e. with a very big value) or if anomalous time is long enough.<p>5. Banshee has the management for projects, users, rules.<p>6. Banshee uses statsd as data source, skyline uses carbon.<p>7. Skyline uses redis as storage. Banshee has no external storage server dependencies. Metrics are stored on disk via leveldb, and rules are stored on disk via sqlite.<p>8. Banshee is young and skyline is no longer actively maintained...
