hawkular wildfly agent - feed ID
by John Mazzitelli
There was some concern that the feed ID autogenerated by the agent might not be what a person always wants (e.g. feed ID for WF10 agents will be the unique UUID of the wildfly server).
So, if you want to define your own feed ID, you can configure it now. In the agent's standalone.xml <storage-adapter> you can specify a feedId attribute if you want. By default, it isn't specified, so the agent will autogenerate a unique feed ID for itself (this should really be the normal mode of operation, but some people like to complain, so I made it easy to shut them up :-)
This is in master. Will be in the next release.

Issues installing Hawkular Service and Alert
by Hassnan Khan
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
running.
Is there any tips you can give on successfully installing the suite?

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.
Thanks,
Manjot
