Package: collectd
Version: 4.10.1-2.1
Severity: normal
Hi.
I think it is not fun having collectd write every 5 minutes, about 100 rrd
files.
I would like to make collectd buffer all statistics for example last 60
minutes,
and after filling this time update real rrd files. Without such precution
hard disk in laptop will often spin-down (becuase of inactvity) and spin-up
(becuase of short period of collectd writing). It can also help
for non laptop cases - on server we could have even 1000 rrd collectd files,
and updating them could mean lots of hard disk seeks (which are slow,
so can significantly affect performance).
I could change interval of dumping data, but this will make collectd not very
usefull.
I think it is easy to just keep data in memory, and from time to time
(or when exiting, or asked to reload files), write it for real.
In this way it could be even usefull to have for example 1 minute
interval. But still write data to rrd every 60 minutes (for desktop
something like 10 minutes will be more appropriate).
Thanks.

In the source distribution, I prefer to keep the default config without
caching, because it is easier to understand for novice users. Also, I
don't want to load the "UnixSock" plugin (which is required for
flushing) per default.
In the Debian package, I'd ditch the dependency to RRDtool and use the
"Network" plugin as default write plugin instead. That's merely my
personal opinion, though.

The bug will be closed with this email. Thanks for the feedback!
