Otherwise I don't see what could be causing the queue lenght of exometer_report_graphite to grow. But if this is so, then why am I seeing a hole in data?

No, exometer_report does no such thing, and neither does exometer_report_graphite (is that the one you’re using?)

If a cache would be added, it would need to be in the graphite reporter. That is, it could well be a core library function, but the caching would need to be done by the reporter instance.

In the case you’re describing, 8 hours of data could end up being quite a lot, so depending on your workload, spooling to disk might be required.
