[Hawkular-dev] Hawkular Metrics + Hawkular Alerts - Phase 0

[Stefan Negrea]

Hello,

That document uses what is already implemented as a base. Phase 0 (a prototype phase) should take the current implementation to the next level. All the things in the document where logical increments to what we have today. The goal was to have a quick Phase 0 to build something that we can get feedback on.

As for the requirements, there are no requirement and there will probably be very little requirements. There is no external entity to give us some requirements at this stage. If you consider that what is proposed in the document is wrong, I open to suggestions. However, I caution against inaction or slow action.

Whatever we do should follow two basic principles:
1) Fast phase, 2-3 weeks of development
2) Build something simple that enables more complicated features in the future


More replies inline below ....


Thank you,
Stefan

That is not what the document states as goals for Phase 0. As the document is written what you described is a prerequisite for Phase 0.

Disconnected APIs are not an integrated solutions. Just as an example, the are issues with the maturity of the APIs on both ends. Until we go through the exercise of trying to integrate the two in a user facing feature we will not see the differences or be able to provide something meaningful to users.

There are no requirements, and probably there will be no requirements in the next month (or even more). That is not the way to approach this.
