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?

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.

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

BTM agent relationship with Hawkular agent
by Gary Brown
Hi
On the team call just now, Heiko raised a question about whether the BTM agent could work with the Hawkular agent. So thought I would start this discussion thread to see what the potential options are.
I currently see two issues:
1) The BTM agent must be configured on the jvm command line as a "-javaagent" to install ByteMan for instrumentation purposes. This is instantiated before the JBoss modules (and therefore subsystems etc) are initialised.
2) The hawkular agent won't necessarily be installed in all monitored servers, and instead remotely monitor some. The BTM agent would need to be installed in all servers where business transactions are executing.
One type of integration that may be possible is in terms of delivering the captured business transaction information to the backend? i.e. the BTM agent locally reports it to the Hawkular agent as a relay?
Thoughts?
Regards
Gary

Maven swagger plugin
by Gary Brown
Hi
The current version of the maven-swagger-plugin used by hawkular doesn't include derived types in the generated docs.
I've tried updating to 2.3.4 and it still does not work. From some basic tests with 3.0.0, it seems to produce the correct content in the json schema - but has slightly different attributes to the plugin configuration, which when updated does not seem to run the template correctly.
The other issue is some API changes when updating the com.wordnik:swagger-* dependencies in line with this maven plugin, as there have been some GAV and API changes.
Its not an urgent issue, but it looks like we will be impacted by changes when we need to upgrade, so thought I would raise the issue.
Regards
