Ensure clocks are synchronized on all nodes
SedangLevel 1Otomatiscassandra
Deskripsi
Enabling Network Time Protocol (NTP), or some equivalent way, to keep clocks on all nodes in sync is critical. The benchmark rates this recommendation Manual; the automated check covers its objective pass criterion. Uses timedatectl (systemd); passes when the kernel clock is reported as NTP-synchronised by chronyd, ntpd or systemd-timesyncd. Compare offsets across nodes as well.
