The observability service supports configuring NTP servers for periodic time synchronization to keep the time of the observability service virtual machine synchronized with your target calibration time. When there is a time offset between the observability service and its associated cluster, or between the observability service and AOC, it can lead to inconsistencies between the metric timestamps recorded by the observability service and the actual times when the cluster generates these metrics. This, in turn, can result in the inaccurate display of monitoring charts in AOC. Therefore, it is recommended to configure the same NTP servers for each observability service as AOC.
Prerequisite
Available NTP servers have been already set up.
Procedure
Log in to AOC, enter the System configuration page, select Observability in the sidebar, and click Settings in the upper right corner.
In the pop-up window, select a deployed observability service, choose Service time. This page displays the current time of the observability service and provides a configuration box for NTP server.
In the configuration box, fill in the NTP server addresses. It is recommended to fill in at least three server addresses. Use the commas (,) to separate them.
Note:
It is recommended to configure the same NTP servers as AOC to ensure that AOC's monitoring charts can display accurate monitoring data.
If AOC has already configured NTP servers, the NTP server addresses configured by AOC will be displayed below the configuration box. Click Enter on the right to fill in the NTP server addresses into the configuration box.
If AOC has not configured NTP servers, a jump button will be provided below the configuration box. Click Configure to jump to AOC's NTP server configuration page, fill in the NTP server addresses to complete AOC's NTP server configuration.
Click Save.
After configuration, when the observability service fails to connect with the NTP server or time is not synchronized, the system will generate an alert on the Alert page. You can resolve this alert according to the provided solution.
