By default, the ExtraHop system synchronizes the system time through the
*.extrahop.pool.ntp.org network time protocol (NTP) servers. If your network environment
prevents the ExtraHop system from communicating with these time servers, you must
configure an alternate time server source.
Before you begin
| Important: | Always configure more than one NTP server
to increase the accuracy and reliability of time kept on the system. |
-
Log in to the Administration settings on the ExtraHop system through
https://<extrahop-hostname-or-IP-address>/admin.
-
In the Appliance Settings section, click
System Time.
-
Click Configure Time.
-
From the Select time zone drop-down list, select your
time zone.
-
Click Save and Continue.
-
On the Time Setup page, select one of the following
options:
- Set time manually
| Note: | You cannot manually set the time for sensors that
are managed by a console or RevealX 360. |
- Set time with NTP server
-
Select Set time with NTP server and then click
Select.
The ExtraHop time servers, 0.extrahop.pool.ntp.org,
1.extrahop.pool.ntp.org,
2.extrahop.pool.ntp.org, and
3.extrahop.pool.ntp.org appear in the first four
Time Server fields by default.
-
In the Time Server fields, type the IP address or fully
qualified domain name (FQDN) for the time servers.
You can specify up to nine time servers.
| Tip: | After adding the fifth time server, click Add
Server to display up to four additional timer server
fields. |
-
Click Done.
The NTP Status table displays a list of NTP servers that keep
the system clock in sync. To sync the current system time a remote server, click the
Sync Now button.
