Hello,
I am happy to announce release 0.23.0 of Hawkular Metrics. This release is anchored by performance and stability improvements.Here is a list of major changes:
- Performance
- Prevent BusyPoolException under heavy load due no available connection and queue reaching max size of 256 (HWKMETRICS-542)
- Gatling load tests have a new option (
loops
) to specify the number of requests per client (HWKMETRICS-559)- Deployment
- Resolved an issue with resource-env-ref in component war (HWKMETRICS-541)
- Updated packaging to support deployments on WildFly 10.1.0 (HWKMETRICS-558)
- REST API
- Updated CORS validation to be applied prior to processing the request; this solves an issue where some content is still returned even thought a bad request status is returned (HWKMETRICS-554)
- Internal Monitoring
- Hostname is now part of the metric id when creating and storing internal metrics (HWKMETRICS-555)
- Hawkular Alerting - Updates
- Added support for newer condition types to the email plugin (HWKALERTS-208)
- Allow ExternalCondition to be fired on Event submission; external conditions can now be matched via Event and Data submissions (HWKALERTS-207)
- Added new NelsonCondition for native Nelson Rule detection; a brand new condition type to perform automatic Nelson Rule detection of misbehaving metrics. (HWKALERTS-209)
