Hi there, here's my 2 cents about the gaps:
From my experience, gaps are normally caused by missing datasets over a period of time. RRD expects data within a time window defined in the "step" and "heartbeat" variables. If data doesn't arrive in this window, the value for the defined time frame is set to "NaN" (Not a number), resulting in not being displayed in the generated image. Missing datasets are often caused by: - Huge service latencies, e.g. if you got lots of services to be checked in a rather short period of time. (Got this with 3k services, which should be checked in a period of 2 minutes -> 25 Checks/second is quite a lot...) - non-fitting service check intervals. If you check your services in a 15 minute interval, but your rrd files expect data every 5 minutes, only every third time frame will be filled, resulting in gaps. Maybe this is of some use.
