mod_admin_shell: Track connected events instead of created The connection events are more appropriate here, where the s2s-created events happens a bit later or earlier in a sessions lifetime depending on its direction and for outgoing connections isn't actually the creation time (which happens immediately after pressing enter, so not very interesting), but rather closer to the connection time.
