We have 500+ servers that we manage.  We have set up monitors for CPU, MEMORY, DRIVES, ETC.  In reviewing the timings on the CPU monitors by WMI, we have found that it does not monitor correctly for the time and interval parameters we have entered.  We also have set up SNMP for the CPU and find that it keeps perfect time for the testing that we are running.  Since we monitor most servers with WMI monitors,  why can't that monitoring system keep the timings as well as SNMP monitors.   We have been using OP Manager for many years.  We are currently on the newest build 11600.  Are there any patches or solutions to this problem.
