We are using Nimsoft monitoring 5.51 version and in our current setup, we have a cluster server (SQL server 2008R2) and we are using sqlserver probe (v 4.11) for monitor the SQL queries.
As we notice in Nimsoft service level manager that SQL server Cache memory is going to more than 300GB. Even we assigned the 60GB max. Memory to SQL server. So we are not sure that this probe is monitor the correct value. Please see the attached screen shot for this probe; let us know if we are missing some setting.
