Monitor PowerShell Script

Dear All,

We nee to Monitor the following command running in powershell.

vxrlink -g shrilife-dg -i 2 status dc-dr

The above command is for database replication. The output of the above
command will be combination of Some text and Numbers in KiloBytes. We need
to trigger an alert when The Number alone exceeds a particular value. Can
it be done??
