StatsAgg v1.5

• New feature : A json-based API for programatically interacting with StatsAgg
• New feature -- 'metric suspensions'. With a 'metric suspension', you can write a regular-expression that will match metric-keys & prevent them from being considered for alerting.
• New feature -- 'Alerts Report'. A page in the WebUI that shows all the important details of an alert on in a table view.
• New feature -- 'Output Blacklist'. A way to prevent metrics that are processed by StatsAgg from being output by StatsAgg to metric storage platforms (Graphite, OpenTSDB, etc).
• New feature -- 'Benchmark'. A way to benchmark the performance of metric groups & metric suspensions.
• Renamed 'Alert Suspensions' to 'Suspensions'. This was done to accomidate the 'metric suspension' feature.
• Changed several pages in the WebUI to load via on-page iframes (instead of transitioning different page). This improves the flow of the UI, as it significantly reduces the need use the browser back/forward buttons.
• Performance enhancements
• Support for Java9+ as runtimes. StatsAgg maintains support for (and is compiled with) Java8.
• The 'Home' page now outputs the number of metric datapoints that are residing in StatsAgg's memory.
• Email alerts now include tags
• Support for single-metric OpenTSDB metrics via the HTTP API
• Support for scientific notation on OpenTSDB metric values
• All UI & APIs are now in UTF-8 (for support of exotic characters)
• Regex tester now allows viewing of 'Metric Recent Values'
• Extra retry logic on sending emails (will try up to 5 times)
• Apache Derby databases will be upgraded to version 10.14.2.0 (this happens automatically)
• If you upgrading from a previous version of StatsAgg, then you will need to run the SQL found in "Upgrade to 1.5.txt" against your StatsAgg database
