Right now we only have one interval for all polling. Do you

all we needed.)
I would have thought that we may want to support different
intervals per
meters, based on the billing rules that one may want to offer.
For
example, I may want to bill compute by the hour but floating
IPs by the
day, hence have a different reporting interval for each.
I was planning to aggregate the values for items being billed over the
longer time frames, but we can make the polling interval configurable.
It will take some work, because of the way the scheduled tasks are
configured in the service and manager (right now we just schedule one
method to run, and it invokes each pollster).
How important is it to include this in Folsom?
Not crucial. I would classify this as Nice to have.
We need a ticket to track this. It's going to require some work on the
agent service, because right now the code that loads the plugins doesn't
have access to the object that knows how to run jobs at regular
intervals. I would rather have a complete tool that works at a single
interval, then go back and enhance it to allow other intervals during
the next release cycle. Is that going to meet your needs?
As I said, this would not be a hard requirement for me, so no issues there.
