Corrections and suggestions on Explorer for android client
by Anuj Garg
Hello everyone,
A tree structure of the explorer is approx ready for the android client and
I was curious if i am wrong somewhere.
First of all, All feeds are collected by call to
/inventory/feeds
feed call for resources
/inventory/feeds/{feed}/resources
call for rec resources and metrics
/inventory/feeds/{feed}/resources/{resid}/recursiveChildren
/inventory/{feed}/resources/{resid}/metrics
Am I missing something?
Thanks

Inventory API question
by Austin Kuo
I was creating 2 different resource types with the same http client at the
same time.
But one succeed, the other failed with the response 400 and body:
{
"errorMsg" : "The transaction has already been closed"
}
Is it not allowed to do so?
Austin.

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

Hawkular Metrics 0.13.0 - Release
by Stefan Negrea
Hello Everybody,
I am happy to announce release 0.13.0 of Hawkular Metrics. This release is anchored by Hawkular integration enhancements, under-the-cover refactorings and fixes, and a new bulk data generation tool.
Here is a list of major changes in this release:
1) Data Generation Tool
* A new tool that generates bulk metrics data to be used in performance and load testing.
* It generates directly Cassandra data files (SSTables), which leads to a very fast generation process for large amounts of metrics data.
* For more details: https://github.com/hawkular/hawkular-metrics/tree/master/data-generator (HWKMETRICS-355)
2) Receive Metrics via Hawkular Bus
* When deployed within Hawkular distribution, the project now accepts metrics via the Hawkular Bus; until now only the REST API had support for Metrics insertion.
* Hawkular Metrics currently support publishing of newly inserted metrics to the bus and receiving metrics via the bus.
* For more details: HWKMETRICS-347, HWKMETRICS-352
3) Sorted Stacked Metrics Results
* When requesting stacked metrics aggregation the results are now ordered (HWKMETRICS-353)
4) External Integrations
* Heapster sink now divides storing to multiple calls. This is an improvement over the initial implementation that had one REST API call per metric (HWKMETRICS-290)
* ptrans now works with a Hawkular Metrics instance protected by Hawkular Accounts via Hawkular distribution (HWKMETRICS-342)
* Grafana integration via Influxdb compatible end-point allows connections to a Hawkular Metrics instance protected by Hawkular Accounts via Hawkular distribution (HWKMETRICS-343)

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.

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
Gary

[GSoC] Hawkular Android Client
by Artur Dryomov
Hi everyone,
This year I will be working on the Hawkular Android client application as
part of the Google Summer of Code 2015 program.
The application itself will use Hawkular API and AeroGear SDK. In coming
days I’ll research these areas, especially documentation, and will try to
create some sort of architecture and basic design.
Thank you all for this opportunity!
Artur.
