Answer 1

You can use awslogs, a python package to tail aws logwatch logs.

Install it with

pip install awslogs

List all the groups with

awslogs groups        

Then select a stream and watch it with

awslogs get staging-cluster --watch

You can also filter logs with matching patterns.

# tail logs of a cluster
awslogs get staging-cluster --watch

# tail logs of a lambda function
awslogs get /aws/lambda/some-service --watch

# print all logs containg "error"
awslogs get staging-cluster --watch --filter-pattern="error"

# print all logs *not* containg "error"
awslogs get staging-cluster --watch --filter-pattern="-error"

See project readme for more information on using awslogs.
