Subject: mqtt plugin: Increase keepalive interval to 60s.
X-Git-Tag: collectd-5.6.0~637^2~6
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=40b0765c2180eba24d1bb4740b5a08754052ab89;p=collectd.git

mqtt plugin: Increase keepalive interval to 60s.

This is the default used by the Mosquitto tools. The new define makes
it possible to easily override this at compile time.
