Hi Askhok,
If you're looking at channel utilization in SimEvents, there is usually a block that every entity is using in the channel, such as a server block, and you can pull the utilization statistic from that to get a statistic of the utilization of the channel.
For throughput, I agree you need to decide which Throughput you want to measure. There is a good example in sedemo_ethernet of how to calculate and measure throughput for one of the controllers connected to the network.

Channel utilization is the portion of the time that there is something being transmitted on the channel, including for all headers and checksums and acknowledgements and so on. This includes all bits that end up getting wasted because a collision is detected. A channel can end up with low utilization of the collision avoidance is too conservative.
For throughput, you need to decide which Throughput you want to measure.
