See logstash collectd documentation:
If no types.db is provided the included types.db will be used (currently 5.4.0)
It seems there were some changes in collectd 5.5.1 (see here). Therefore, you need to explicitly set the types.db, for example:
input {
udp {
codec => collectd {
typesdb => [ '/usr/share/collectd/types.db']
}
}
}
See https://collectd.org/documentation/manpages/types.db.5.shtml in order to determine the location of types.db in your installation.
