Hi Simon,

So collectd acts as a statsd server, and the metrics are aggregated and dispatched to the collectd daemon.
Collectd’s write plugins then output the stats to wherever we want them to go.

In order to interact with gnocchi using statsd, we require collectd to act as a statsd client and dispatch the metrics to gnocchi-statsd service.

Regards,
Emma

I'm not sure what that means?
https://collectd.org/wiki/index.php/Plugin:StatsD seems to indicate it
can send metrics to a statsd daemon.

Nope that is the opposite: collectd can act as a statsd server. The man page [1] is clearer than the collectd Wiki.
