Subject: write_graphite plugin: Implement the StoreRates option.
X-Git-Tag: collectd-5.1.0~33^2~11
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=3e9d0babd83c359ffa114c0bc0f808cade99e3e8;p=collectd.git

write_graphite plugin: Implement the StoreRates option.

Most of it was already present in the code anyway, so I just added the
appropriate config handling.
