Re: [chrony-users] All network sources unusable

[ Thread Index | Date Index | More chrony.tuxfamily.org/chrony-users Archives ]

Apologies, Denny! I am unhappy myself that I do not respect the simplest mailing list etiquette such as fixed width font, sensitive line wrap and encoding since I switched to MacOS and Postbox. I guess it's time to get mutt up and running like in the old Linux days... Back on topic - I hope you can read Miroslav's reply and my response with the solution of the issue. 

Many thanks for your support.

Your actual values for will be different of course, but at a minimum there should be non zero values present for Reach, Last Sample, NP and Span. A value of 0 for NP, 0 for Span, 2000.000 for Freq Skew and 4000ms for Std Dev are clear indications that the source is not being tracked.

As far as I understand 377 indicates that the network sources can be accessed, and the fact that the measurements.log file is constantly updated with readings from those sources shows that data is being received.
Not sure why the Reach value for the PPS source is 113. A few minuts later that value increased to 372, just to go down again afterwards.
Here is a the output of "chronyc ntpdata" from one of the external sources

Try this:

  chronyc -m sources sourcestats
This will print the sources and then the source stats. I suspect that the other sources you have are not actually being polled or are not reachable. Check the 鈥淩each鈥� column in sources.
