    Description

      Steps to reproduce:

      1. Discover disk C: on Windows host by Windows physical disks by Zabbix template
      2. Shutdown Windows host and wait 15 minutes
      3. Start Windows host so there is a big load on the disk during startup

      Result:

      Observe problem "C:: Disk is overloaded (util > 95% for 15m)"

      Expected:

      This problem must only occurs if the host actually experienced high disk load during 15 minutes in a row, not 1 min during startup.

      The trigger prototype is:

      min(/Windows physical disks by Zabbix agent/perf_counter_en["\PhysicalDisk({#DEVNAME})\% Idle Time",60],15m)>{$VFS.DEV.UTIL.MAX.WARN} 

      min() doesn't care how many samples of data there are within 15 given period as long as there is just one sample.
