Feature packs - a new way of packaging for WildFly
by Peter Palaga
Hi *,
Some of you might have heart of the $subj already. For others: wf
feature packs are lightweight recipes for building fat WF distros.
wildfly-feature-pack-build-maven-plugin typically produces a zip
containing some xml config but no jars/wars/ears.
wildfly-server-provisioning-maven-plugin is there to take the recipes
and make fat distros out of them.
Why I am bringing this topic: It seems that feature packs could help us
to consolidate all our modules, itest distros and final distros in such
a way that configuration will not be duplicated anymore. I hope to be
able to do this together with the upgrade to WF10.
There is not much docs about the two plugins except for this terse wiki
page: https://developer.jboss.org/wiki/WildflyBuildProcess
Nevertheless, examples can be found in wildfly and wildfly-core source
trees.
We started producing a feature pack in Agent recently:

Thanks,
Peter

Alpha7 startup problem
by Van Dillon
Hi,
I'm running into a problem trying to start Alpha7 AIO on both Windows 7 and
Docker.
In Windows I set 'org.hawkular.data.dir' before trying to run. This worked
well in Alpha6. When I run I get a lot of WARN entries:
2015-11-19 17:01:16,780 WARN [com.datastax.driver.core.Connection]
(cluster4-nio-worker-0) Error closing channel:
io.netty.channel.ChannelException: java.net.SocketException: Socket is
closed
Then I get one or more of these FATAL entries:
2015-11-19 17:01:32,351 FATAL [org.hawkular.accounts.common.internal]
(EE-ManagedExecutorService-default-Thread-2) HAWKACC150005: Could not

(com.datastax.driver.core.TransportException: [/127.0.0.1:9042] Cannot

Finally the server shuts down with:

In Docker the log has the same FATAL and ERROR entries but does not have
the WARN entries.
Any help would be much appreciated.
Thanks,

securing download WAR
by John Mazzitelli
Today we have a simple WAR [1] that lets you download the agent .zip and the agent installer:
1. Download the agent distro: http://localhost:8080/hawkular/wildfly-agent/download
2. Download the installer: http://localhost:8080/hawkular/wildfly-agent/download?installer=true
That second one you can submit a FORM POST with some additional installer config settings. In fact, that /download URL points to a single servlet - its just if you POST with "installer=true" (or pass it in as a GET query string) you'll get the installer instead. We could change this if need by (say "/download" for the agent distro, and "/installer" for the installer).
The question I have is - what do I need to do to get that second one "secured" with an Accounts login?
We want to keep the "/download" URL such that it doesn't require a user/pass just to serve the agent distro zip (that is just the same one you build via mvn - there is nothing that needs to be secured here - plus, the installer needs to download it later and we don't want to have the installer log in just to download the zip).
But that second one, we are going to need the Accounts credentials because the installer will need to do things like create an offline token for the user so it can be put in the installer config - or be able to ask Accounts for the offline token for that user.
Before anything like that can be done, I think we need to put accounts in front of that WAR [1] . What needs to be done here for that?

Cassandra and DataStax driver versions
by John Sanda
There is a PR[1] open for hawkular-parent that upgrades Cassandra from 2.2.0 to 2.2.2 and the driver from 2.2.0-rc2 to 2.2.0-rc3, so now is a good time to discuss this. Earlier this week, Cassandra 3.0 was released[2]. There are some substantial changes including a rewrite of the storage engine to be better optimized for CQL, materialized views, and range deletes to name a few. The driver repo has been maintaining separate branches for each Cassandra branch which has been causing a lot of maintenance overhead. It was announced earlier today on the driver mailing list that the 2.2 branch, which we are currently using, has been merged into the 3.0 branch[3]. There will be no further development on the 2.2 branch. The driver is designed to be backwards compatible such that newer versions of the driver can be used with older versions of Cassandra. This means we could upgrade the driver without upgrading Cassandra; however, I think it makes sense to upgrade Cassandra as well.
Are there any questions, comments, concerns, objections, etc.?

Standalone Metrics+Alerts
by John Sanda
Over the past couple weeks I have been working on a standalone deployment of Metrics and Alerts. The work is being tracked under HWKMETRICS-311. One of the changes I made was to introduce a new maven module in the hawkular-metrics project that builds and assembles a WildFly 10 distro which includes Metrics and Alerts. Should this new module and other integration modules live in the main hawkular repo instead of the component repo?

more agent installer enhancements
by John Mazzitelli
Just a couple things to mention:
1) you can ask the server to give you an agent installer with the passwords encrypted. If you pass in "encryption-key" when you ask for the installer the passwords in the installer config file will be encrypted (weakly, but still encrypted - its more than obfuscation) so you can pass around the installer jar without having the passwords inside it in clear text. You have to remember to pass that same encryption key to the installer when you install (using --encryption-key cmdline option)
2) The installer will default its wildfly-home to the current working directory if you don't give it one. That way, you can copy the installer jar right to a wildfly home location, run "java -jar installar.jar" without specifying --wildfly-home and it will use the wildfly home it is living in.

Hawkular goodies / swag
by Thomas Heute
I'd like to open the discussion to *anyone* on something light: Hawkular
Goodies ;)
I would like to get some goodies to give away at conferences, for
contributors...
I would like to have something that is not going to the trash right away,
something you would want to have (and doesn't cost a fortune ;)).
I am personally not fond of T-shirts as we usually get many at conferences
unless the design is really fun/original.
So please make your proposals and then we can vote, we may end with 2
results, cheaper to spread more/slightly more expensive for special
occasions.
Maybe you saw/received something fun/useful in the past.
Example of something original:
Atlassian socks:

Don't be shy :)
If we go to the end with your idea, you would definitely get the first item
;)
