[Hawkular-dev] Is there any guide for HawkularMetrics launch or usage?

Hello everyone, I am a really fan of Hawkular Metrics TSDB, I have installed ccm, downloaded a distribution binary and launch them by `ccm create` and standalone.sh respectively. But now I am confused how to use the database: I have read the UserGuide on the official website, but it seems there is no specific port mentioned. I tried `lsof -i` and look up for the "hawkular" related entries, but all failed to issue a POST command. SO I am really appreciate for any help if you sir can name any keyword, sincerely thank you very much.
