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
<https://issues.jboss.org/browse/HWKMETRICS-542>)
- Gatling load tests have a new option (loops) to specify the number
of requests per client (HWKMETRICS-559
<https://issues.jboss.org/browse/HWKMETRICS-559>)
- *Deployment*
- Resolved an issue with resource-env-ref in component war (
HWKMETRICS-541 <https://issues.jboss.org/browse/HWKMETRICS-541>)
- Updated packaging to support deployments on WildFly 10.1.0 (
HWKMETRICS-558 <https://issues.jboss.org/browse/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
<https://issues.jboss.org/browse/HWKMETRICS-554>)
- *Internal Monitoring*
- Hostname is now part of the metric id when creating and storing
internal metrics (HWKMETRICS-555
<https://issues.jboss.org/browse/HWKMETRICS-555>)
- *Hawkular Alerting - Updates*
- Added support for newer condition types to the email plugin (
HWKALERTS-208 <https://issues.jboss.org/browse/HWKALERTS-208>)
- Allow ExternalCondition to be fired on Event submission; external
conditions can now be matched via Event and Data submissions (
HWKALERTS-207 <https://issues.jboss.org/browse/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
<https://issues.jboss.org/browse/HWKALERTS-209>)
