Res_statsd: invalid metric type `m`

Hi,

I’m using the res_statsd with statsd agent (Centos 7) and Asterisk 15.1.5 . Asterisk send the stats to the agent locally on port 8125

U 127.0.0.1:50298 -> 127.0.0.1:8125
stasis.message.ast_channel_varset_type:1|m

U 127.0.0.1:50298 -> 127.0.0.1:8125
stasis.message.ast_channel_snapshot_type:1|m

U 127.0.0.1:50298 -> 127.0.0.1:8125
stasis.message.ast_channel_snapshot_type:1|m

U 127.0.0.1:50298 -> 127.0.0.1:8125
stasis.message.ast_channel_varset_type:1|m

U 127.0.0.1:50298 -> 127.0.0.1:8125
stasis.message.ast_channel_hangup_request_type:1|m

U 127.0.0.1:50298 -> 127.0.0.1:8125
stasis.message.ast_channel_snapshot_type:1|m

But statsd agent seems to not support this metric type ‘m’

Is that normal ?

Thanks for any help,
