as per IBM documentation, it says
Collecting monitoring data might require some instructions that are relatively expensive computationally, such as obtaining system time. To reduce the effect of real-time monitoring, the medium and low monitoring options measure a sample of the data at regular intervals rather than collecting data all the time.

Does anyone know what IBM means when it says "Expensive computationally", does it mean the CPU utilization is more or does it mean it will slow down the transactions and Queue throughput time will be more?

Yes and yes.

It burns more CPU to perform the named tasks, and the transactions will take longer as these additional system tasks are added to them.

Vitor, thanks for reply. If it just increases CPU we are fine with that as we have enough CPU on server but my concern is if we keep MONCHL high for a sender channel would that slow down the channel outgoing throughput?

It's a valid concern.

The question you need to ask is if the additional information you obtain from having MONCHL set to high is worth the delay in the sender channel.

Only you can answer that because only you know the use you're putting the monitor information to and the impact of any delay in the sender channel on your solution.

Enjoy.
