Anton, yes, it can be a little confusing. The Hawkular project is an
end-to-end monitoring and management tool focused on Red Hat software.
Today it basically offers a Wildfly agent for discovering and managing
app servers, their hosted apps, and all of the things that make up those
apps. What is can handle grows with every release. Hawkular leverages
a bunch of components to perform that job. There is HK-Inventory to
represent a network of inventories resources (like an app server, a
datasource, a jvm, etc), HK-Metrics as a Cassandra-backed time-series
store, HK-Alerts as a Drools-backed alerting tool, HK-Accounts as a
KeyCloak backed multi-tenant/auth/authz tool, HK-Console for UI, HK-Bus
for a comm backbone, etc..
Some of the HK components, namely HK-Metrics and HK-Alerts support
standalone deployment outside of Hawkular. They are named
Hawkular-Metrics and Hawkular-Alerts because they have been developed as
part of the Hawkular project, but they can be used independently. Hope
that helps...

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.
Thanks Jay - this sounds really cool!
I have heard a few times now that hawkular components can be used
outside of the hawkular framework. What exactly is the hawkular
framework? As an outsider I am learning about Hawkular and its
features. There is good documentation on the features, but the
underlying framework, not so much.
Also, regarding documentation, I could not find how to store any
'metric' or data. Specifically, I am looking to store not just a
metric but a pojo.
