Use the additional flags to can to retrieve and watch logs from a specific instance whithout Child instances. 
EXAMPLE: logs --addr http://192.168.1.1 --namespace admin --instance 9b0e45b5-5e7e-4006-93e7-6764e8379e98 --filter ID --type MATCH 9b0e45b5-5e7e-4006-93e7-6764e8379e98
It is also possible to watch logs of a specific workflow, state-id and array-index by providing the values as arguments the array-index is optional
EXAMPLE: logs --addr http://192.168.1.1 --namespace admin -instance 9b0e45b5-5e7e-4006-93e7-6764e8379e98 --filter QUERY --type MATCH getwf getter 2
To filter by the level of the log use -filter LEVEL --type MATCH level or -filter LEVEL --type STARTING info, supported levels are debug, info, error and panic
