July 2016 - hawkular-dev - Jboss List Archives

by Juraci Paixão Kröhling

Team, Hawkular Services 0.0.6.Final has just been released. The only functional change between this and the previous version is that Hawkular Services now reports itself as a "Hawkular" server, instead of "Wildfly" (HAWKULAR-1098) As the previous distributions, the Agent has to be configured with an user. This can be accomplished by: - Adding an user via bin/add-user.sh like: ./bin/add-user.sh \ -a \ -u <theusername> \ -p <thepassword> \ -g read-write,read-only - Changing the Agent's credential on standalone.xml to the credentials from the previous step or by passing hawkular.rest.user / hawkular.rest.password as system properties (-Dhawkular.rest.user=jdoe) You can find the release packages, sources and checksums at GitHub, in addition to Maven: https://github.com/hawkular/hawkular-services/releases/tag/0.0.6.Final Shortcuts for the downloads: Zip - https://git.io/vKwxm tar.gz - https://git.io/vKwxI - Juca.

Integrate metric data with inventory

by Austin Kuo

Hi, I’m currently working on vertx metric agent, my job is to enable the inventory such that users can view the inventory and corresponding metrics. My question is that how “real metric data” and “inventory metrics” are matched? Is it simply bound via id? Thanks, Austin

Hawkular Services vs Hawkular Community

by Thomas Heute

(If you don't know about Hawkular Community you can skip this email completely) After some discussions about Hawkular Community, here is our conclusion: - We will not have a separate Hawkular Community repository - We will ship 2 distributions for Hawkular Services, - one for dev/demo/quick test that will have an embedded Cassandra, a default user and the embedded agent enabled (This is what you get when building Hawkular Services today with "-Pembeddedc -Pdev"). - the other one that requires an external Cassandra server, no default user and the agent being disabled. - We'd like a simple UI to explore data (metrics, inventory, alerts), but this is not a priority, if someone in the community is looking for an Angular project it would be great, please contact us on this mailing list. We would advertise that work in the "Client" section of the revamped hawkular.org [1] as a separate download. (Note that this would likely be purely static content and could even be made available on a CDN) - For other side projects that are not mature to be included in Hawkular Community or side projects, they will be listed either in the "client" or "labs" section of the revamped website [1] depending on their maturity and scope. Thanks, Thomas [1] WIP: http://209.132.178.114:10188/

inventory and resource config props

by John Mazzitelli

I ran into an Inventory issue today. I don't know what is the expected behavior - I hope what I saw isn't expected :) I ran the agent and it added everything in inventory successfully. I then shutdown the agent, added a new resource configuration property definition to a resource in the agent configuration, then re-ran the agent. The agent successfully found and attempted to add the new resource configuration property via the inventory bulk/ API, but inventory never stored it. When I look in inventory, I do not see my new resource configuration property attached to the already existing resource. The resource config props that were on the resource originally are still there, but the new one was never added. The agent builds the bulk payload in its AsyncInventoryStorage class - specifically, you can see adding the resource config props here: https://github.com/hawkular/hawkular-agent/blob/master/hawkular-wildfly-a... What is wrong?

Post a metricType under a resourceType, 400 bad request

by Austin Kuo

Hi all, I was trying to create a metric type under my resource type called “MYRT”, Here’s body look like: {“collectionInterval”: 30, “id”: “metricTypeId123”, "type": "COUNTER", "unit": "NONE"} I posted this to url: http://localhost:8080/hawkular/inventory/deprecated/feeds/vertx-localhost... It gave me 400 bad request. But I posed to http://localhost:8080/hawkular/inventory/deprecated/feeds/vertx-localhost... . And it worked. Wondering why is that? Thanks

agent blog on prometheus support

by John Mazzitelli

I decided to blog about this since it, too, is a relatively unknown feature, but could be helpful to those that need to collect metric data from Prometheus endpoints. See: http://management-platform.blogspot.com/2016/07/collecting-prometheus-dat...

PR Review Request: https://github.com/hawkular/hawkular-apm/pull/475

by Gary Brown

Another small change - to consolidate environment variables used for configuration. Selection of technology used is now based on a prefix used on the value, rather than on use of different environment variables. Regards Gary
