"dumponexit" feature of chrony

Solution Verified - Updated -


There is introduction of "dumponexit" directive in official admin guide, however it is not found in chrony manpage. Is this "dumponexit" still supported?

Configuring basic system settings RHEL8

System Administrator’s Guide RHEL7

    If this command is present, it indicates that chronyd should save the measurement history for each of its time sources recorded whenever the program exits. (See the dumpdir command above). 

The following configuration in /etc/chrony.conf works as expected.

dumpdir /var/run/chrony
