Is it possible to track UP/DOWN status of micro-services registered with
Eureka and fire email notifications if a service goes down? If yes, please
point me to right direction.
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.

My name is Hassnan Khan and I work at Fandango in the NOC department. We
use an ELK stack to process our logs into readable data that we see on
Kibana (4.6.4) / ElasticSearch 2.4.x. We've been trying to get a standalone
alerting system and haven't had much luck. I came across Hawkular Services
+ Alerts and thought this is something we could possibly use.
Unfortunately, we haven't been able to install it successfully. We've tried
all the installation guides on github + hawkular blogs and keep getting an
error when trying to connect to Cassandra even though it is obviously
Is there any tips you can give on successfully installing the suite?
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.
How do we explain the drops in requests in the following example:
Shouldn't it always be the same load ?
Do we know if it's an it's an issue in APM, or is it that the load
balancing "lose" some requests as we scale down a server ? or else ?
