Would like to know if there is any specific monitoring probe available for Zerto?
Release : 20.4
We do not have a probe for Zerto, but based on a review of the following it looks like you could use the ntperf probe to monitor the performance counters that it exposes:

The restmon probe may also be another option if Zerto exposes monitoring data via rest calls.
