Timex icon



Plugin: timex.plugin Module: timex.plugin


Examine Timex metrics to gain insights into system clock operations. Study time sync status, clock drift, and adjustments to ensure accurate system timekeeping.

It uses system call adjtimex on Linux and ntp_adjtime on FreeBSD or Mac to monitor the system kernel clock synchronization state.

This collector is supported on all platforms.

This collector supports collecting metrics from multiple instances of this integration, including remote instances.

Default Behavior


This integration doesn’t support auto-detection.


The default configuration for this integration does not impose any limits on data collection.

Performance Impact

The default configuration for this integration is not expected to impose a significant performance impact on the system.



No action required.



The configuration file name for this integration is netdata.conf. Configuration for this specific integration is located in the [plugin:timex] section within that file.

The file format is a modified INI syntax. The general structure is:

    option1 = some value
    option2 = some other value

    option3 = some third value

You can edit the configuration file using the edit-config script from the Netdata config directory.

cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
sudo ./edit-config netdata.conf


At least one option (‘clock synchronization state’, ‘time offset’) needs to be enabled for this collector to run.

Name Description Default Required
update every Data collection frequency. 1 False
clock synchronization state Make chart showing system clock synchronization state. yes True
time offset Make chart showing computed time offset between local system and reference clock yes True



A basic configuration example.

  update every = 1
  clock synchronization state = yes
  time offset = yes


Metrics grouped by scope.

The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels.

Per Timex instance

These metrics refer to the entire monitored application.

This scope has no labels.


Metric Dimensions Unit
system.clock_sync_state state state
system.clock_status unsync, clockerr status
system.clock_sync_offset offset milliseconds


The following alerts are available:

Alert name On metric Description
system_clock_sync_state system.clock_sync_state when set to 0, the system kernel believes the system clock is not properly synchronized to a reliable server
