Collect logs for eventing components by fluent

Ask your question here:

For now, we can not collect logs for eventing components by fluent, because the config of logs path for fluent look like:

/var/log/containers/*user-container-*.log,
/var/log/containers/*build-step-*.log,
/var/log/containers/controller-*controller-*.log,
/var/log/containers/webhook-*webhook-*.log,
/var/log/containers/*autoscaler-*autoscaler-*.log,
/var/log/containers/*queue-proxy-*.log,
/var/log/containers/activator-*activator-*.log

and the log files for eventing in /var/log/containers/* look like :

eventing-webhook-6f88588bcb-nctjn_knative-eventing_eventing-webhook-6ff5369cff9b5174f20dc881efde082a872104dfe3c488fe0b824b29ea78df09.log

so we need do some changes:

/var/log/containers/controller-controller-.log -> /var/log/containers/controller-controller-.log, /var/log/containers/webhook-webhook-.log, -> /var/log/containers/webhook-webhook-.log,

and add paths for eventing dispatcher,filter,ingress,adapter:

/var/log/containers/dispatcher-dispatcher-.log
/var/log/containers/filter-filter-.log
/var/log/containers/ingress-ingress-.log
/var/log/containers/adapter-dispatcher-.log

Is that right? any guidance about this? I am not sure this is the right place to do these changes.

The monitoring plugin/bundle was deprecated in v0.14, and our intention is to remove it, so I don't think we really want to be making functional changes here.
