title: Synchronization of operating system time
agents: windows
catalog: os/misc
license: GPL
distribution: check_mk
description:
 This check is a simple check of the correct setting of the current
 system time of the target host. It simply compares the local time
 on the monitoring server with that measured by the agent on the
 target host. It is not very accurate since it does not account for
 the systematic time delay between the output of the time by the agent
 and the actual processing of that data by Check_MK.

 Its advantage - however - is that it works on any Windows host (with
 an agent of version of 1.1.10 or later) - regardless of the method used
 to synchronize the time.

 Levels can be set for making the check warn/crit if the time difference
 exceeds the configured limits.

perfdata:
  the time difference in seconds

inventory:
  One service will be created for each host supporting this check.
  Currently this is the windows agent in version 1.1.10 or later.

[parameters]
warning(int): Time difference in seconds at which the check goes to warning.
critical(int): Time difference triggering a critical state.

[configuration]
systemtime_default_values(int, int): Default check levels in seconds of time diference. This is preset to {(30, 60)}.
