Port mirroring question

Quick one for you folks, need clarification about traffic direction.
1. Ingress means coming into the vDS, so coming out of a port (say VM1). So we mirror traffic coming out of VM1, correct?
2. Egress means coming to VM1, correct? So traffic bound for VM1?
I've read a few blog posts on VMware.com but this wasnt completely clear.

Best use case I've read about port mirroring is for IDS. Netflow is for netflow analyzer.

We can then set up an appliance on the span port to capture the L2 traffic of that vlan.
