Time-sync check tool for CDF, which continuously checks the system time of all Master / Worker nodes

0 Votes

The CDF Master and Worker nodes might not be synced by a central time service.  As a consequence the local system time on these nodes might differ and could "confuse" K8S, if the difference is bigger than a few seconds. 

Already at least one customer ran into this problem.

Just checking the system time consistency during initial CDF installation / start-up is not sufficient, but these checks need to get repeated periodically in case no central time services is switched-on.

Hello,

It is very unlikely that we would develop such a tool as UNIX/LINUX have Ntp and more recently Chrony to handle this. Customer that do no have any time sync between their datacenter servers need to improve their setup and add it. Synchronized server updates, configuration management, torubleshooting all become increasingly difficult if servers do not have the same time set.

Thanks,

Ralf

Chrony service is required as part of our system checkpoint.
Here is RHEL Chrony service and synchronization information - https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/system_administrators_guide/sect-using_chrony
