Use them both for best results. Harvest will query metrics directly from your controllers, but can also get many other metrics from OCPM. Capacity metrics I think are only available when Harvest queries OCPM.
We use both, and frankly I find I much favor Harvest/Grafana. Takes a little work to get it going, but that looks much easier with 1.3 release.

That chart is for a really old version. OCPM is at version 7.0 (and 7.1RC) and is much improved over 2.x. That said, I still wouldn;t rely on it alone, without Harvest.
