Clock offset

Will there be an option in the future to have a yellow & red clock offset threshold ? presently there only seems to be a yellow threshold. Thank you, ~Steve

There's an option in hobbit-clients.cfg: # CLOCK maximum-offset # If the system clock of the client differs from that of the Hobbit # server by more than "maximum-offset" seconds, then the CPU status # column will go yellow. Note that the accuracy of this test is limited, # since it is affected by the time it takes a client status report to # go from the client to the Hobbit server and be processed. You should # therefore allow for a few seconds (5-10) of slack when you define # your max. offset. # It is not wise to use this test, unless your servers are synchronized # to a common clock, e.g. through NTP. Hope is useful. RB

It will only go yellow, because the test is not very accurate - it depends on the communication between the client and the server, and also on whether the Hobbit server has OK time or not. Regards, Henrik

Yes, I understood that. I am not performing +- 5 second checks, but more like +- 150 (yellow) +- 300 (red) checks. So in my scenario, I think there is plenty of buffer time for client/server communication issues.
