[hobbit] Log sizes

[Kevin Hanrahan]

Thanks, 
 I can probably say it is no bug. I do have a few hosts listed twice. I was
trying to build different views for different departments. I now think this
is the wrong approach and I am supposed to use pagesets??...is that correct?

This means that an update of the RRD file failed. The actual text describing
the error is provided by the rrdtool library - in this case, it refused to
update the file because it's been less than one second since the last
update.

So how can it happen that it tries to update the same RRD file twice in a
second ? I've seen it mostly with data from network tests, e.g. if you
happen to have the same host or test listed twice in your bb-hosts file.
With client reports (cpu, disk, ..) it can happen if you have two clients
reporting with the same name. Or it may be a bug in the hobbit larrd
handler, so it mistakenly sees the same data twice.

No.

Yes, but they are kept open by the various hobbitd* processes running.
hobbitlaunch and hobbitd will re-open the logs when you send them a SIGHUP,
but the various hobbitd_* modules don't. I'll get that fixed.
