Hi,
Satellites are what you think, but they don't really lower the load, because the Master still needs to do the 'backend' part of the polling, only the pollers are distributed.
All data is stored in the master. So, it still have around the same load.
This is useful in situations where the master can't access the remote network directly, or when you want 2 pollers polling the same host in case some of them die.
I expect that in the future the satellite system will case lighter loads.
Another option is implementing some patches sent to me by Anders Karlsson that make the RRD Storage and Graphing distributed too, so the master will ask the childs (slaves) for graphs, but the polling is local to the slave.

Hello,
As i'm getting familiar with JFFNMS i discovered a potentialy interesting feature: satelites. Although I can't find any information about how I should use it, I guess you can use it to distribute the load JFFNMS is generating (which can be high!) on more machines. Can somebody tell me more about the principle behind satelites?
With regards,
Tjerk Nan
