depending on your needs, you could find that your main
needs are metrics and alerting, maybe BTM as well, and
those components can both be used in a "standalone" mode,
independent of the Hawkular framework. REST APIs are the
typical way to interact with Hawkular. Hawkular Alerts
has no built-in UI, I'm not sure if Metrics comes with any
visualization outside of Hawkular.</blockquote>

<div class="gmail_extra">The BTM module looks interesting,
however I am concerned about maintenance. For example, in the
configuration example on <a moz-do-not-send="true"
href="http://www.hawkular.org/docs/components/btm/index.html">http://www.hawkular.org/docs/components/btm/index.html</a>,
if I were to change the switchyard service names it would
break - and I assume there would be no compile time errors?
Therefore, using a strongly typed hawkular client to
communicate with hawkular would be preferred.</div>

<div class="gmail_extra">With Metrics, is it possible to add
custom data? To illustrate, I have the following use-case:</div>
<div class="gmail_extra"><b>log events of interest - </b>as a
product owner I would like to use all user events of interest
so that the user and system auditors can see what and when a
user did something. So, we would log "user John, with user id
1234 logged in at wed 25 oct 17:46. So we would be logging a
custom event, and storing custom data.</div>

Metrics and Alerts can both be used outside of the Hawkular
framework so really you can store any metric you like, or alert on
basically any data you like. As for Events, the next release of
Hawkular Alerts (0.6.0) will include a new Events feature that you
may find interesting. Whereas Alerts are relatively rare, typically
involve human interaction, and run through a simple life-cycle;
Events are likely much more numerous, representing any sort of
happening that a client wants to persist. The interesting thing
about Events in HK-Alerts is that they can be inserted directly via
API or can be generated via Trigger, like an Alert. And Events can
also be used as Trigger conditions, to contribute to further Alert
or Event generation.<br>
