hawkular-alerts integration with prometheus, elasticsearch, kafka

by John Mazzitelli

I wrote a blog to demo hAlerts and its integration with Prometheus, ElasticSearch, and Kafka, showing how we can fire alerts and notifications based on things happening with Prometheus metrics, ElasticSearch logs, and Kafka stream data. I need it reviewed and merged for it to be published: https://github.com/hawkular/hawkular.github.io/pull/334 The demo video is here: https://youtu.be/mM1mwJneKO4

"Getting Things Done" (David Allen) System: Artificer

by Brett Meyer

FWIW, I've been experimenting with Artificer as a "Getting Things Done" solution, mainly as a bit of dogfooding. However, it fits in surprisingly well. I'll be maintaining a demo that showcases a GTD ontology/classifier system, showing Artificer as not-just-another-artifact-repo, but also a powerful information and reference system. https://developer.jboss.org/en/artificer/blog/2015/03/31/getting-things-d...

Error connecting to Cassandra - com.datastax.driver.core.exceptions.InvalidQueryException

by Dhillon, Manjot

Hello, I am trying to start hawkular services, version hawkular-1.0.0.Alpha13-SNAPSHOT. As per the documentation, I am using Cassandra version 3.0.12. On starting the hawkular service, I see the following error - 33m01:58:08,209 WARN [org.hawkular.alerts.engine.impl.CassDefinitionsServiceImpl] (Thread-239 (ActiveMQ-client-global-threads-15127043)) Could not connect to Cassandra cluster - assuming is not up yet. Cause: com.datastax.driver.core.exceptions.NoHostAvailableException: All host(s) tried for query failed (tried: apsrd6612.uhc.com/10.204.85.28:9042 (com.datastax.driver.core.exceptions.InvalidQueryException: unconfigured table schema_keyspaces)) The cassandra driver included with the hawkular service - cassandra-driver-core-2.2.0-rc3.jar, which may be causing the issue.
