A program which forwards stdout from a child and applies custom forward logic.
Intercepting logs can be difficult. Full blown solutions like k8s services meshes exists. We aimed for a simple solution.
Logtee executes a child program and intercepts the stdout of the child. It redirects the stdout of the parent (logtee) and applies custom forward logic. Forward logic could be filtering specific events.
rdmd -Jfeatures/support src/logtee.d --forwarder features/support/forward -- executable-child-program.
- start mongodb
- provide forward
- write the data of your child program (in this example '{}') to stdout and to mongodb
src/logtee.d --forwarder features/support/mongo/forward -- echo {}.
- forward stdin
- connect stderr
