NTP stands for Network Time Protocol. It is used to synchronize the time on your Linux system with a centralized NTP server. A local NTP server on the network can be synchronized with an external timing source to keep all the servers in your organization in-sync with an accurate time.
If the NTP check is enabled in the Sysdig agent, it reports the time offset of the local agent from an NTP server.
This page describes how to edit the configuration to collect information, the metrics available for integration, and a sample result in the Sysdig Monitor UI.
Sysdig Agent Configuration
Review how to Edit dragent.yaml to Integrate or Modify Application Checks.
Sysdig's dragent.default.yaml does not provide any
configuration for NTP
Add the configuration in Example 1 to the
dragent.yaml file to enable
dragent.default.yaml directly; always edit only
- name: ntp interval: 60 pattern: comm: systemd conf: host: us.pool.ntp.org offset_threshold: 60
host: (mandatory) provides the host name of
offset_threshold: (optional) provides the difference (in seconds) between the local clock and the NTP server, when the
ntp.in_syncservice check becomes
CRITICAL. The default is
ntp.offset, the time difference between the local clock and the NTP
reference clock, is the primary NTP metric.
See also NTP Metrics.
CRITICAL if the NTP offset is greater than the threshold
dragent.yaml, otherwise OK.
Result in the Monitor UI
