Configure system time servers

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.
  1. Log in to the Administration settings on the ExtraHop system through https://<extrahop-hostname-or-IP-address>/admin.
  2. In the Appliance Settings section, click System Time.
  3. From the Select time zone drop-down menu, select your time zone.
  4. Click Save.
  5. In the Time Servers area, type the IP address or fully qualified domain name (FQDN) for the time servers.
    You can specify up to nine time servers. 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.
    Tip:After adding the fifth time server, click Add Server to display up to four additional timer server fields.
  6. 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.
