A collection set containing a single response time resources written to Kafka looks like the following:
2020-04-12T04:34:34,986 | DEBUG | kafka-producer-network-thread | producer-1 | KafkaPersister | 435 - org.opennms.features.kafka.producer - 26.1.0.SNAPSHOT | persisted
collection timestamp: 1586666074984
to kafka with key 0
2020-04-12T04:34:34,994 | ERROR | pool-13-thread-1311 | CollectionSetMapper | 435 - org.opennms.features.kafka.producer - 26.1.0.SNAPSHOT | error while trying to match node
1. The "location" field of the response time resource should be populated so we know what location it relates to.
2. The IP address should be easy to parse - right now it's concatenated with [JMX-Minion]?
3. An error is logged if the node is null, but this is expected in the case of response time resources.
