Replacement of ntp with chrony

In Oracle Linux 8 and later, chrony replaces ntp for the management of NTP. The following table shows file, command, and terminology equivalents between ntp and chrony.

ntp chrony
/etc/ntp.conf /etc/chrony.conf
/etc/ntp/keys /etc/chrony.keys
ntpd chronyd
ntpq command chronyc command
ntpd.service chronyd.service
ntp-wait.service chrony-wait.service
ntpdate and sntp utilities chronyd -q and chronyd -t commands

The ntpstat utility which is available in the ntpstat package, now supports chronyd. Thus, you can still use the utility in Oracle Linux 8 and later. The command generates output that's similar to when it's used with ntp.
