Ok, so you implemented the metrics command as a new function which
does the same as the serverstats command, but uses a different output
format. I assume you would extend it later to include also the
tracking, sources and sourcestats data. That would be a lot of
As I said in the previous mail, I'd rather see it implemented as a
different output format for the existing commands. A new chronyc
option could be added to select the format, with default being the
currently used human-readable output. A new printf-like function would
be added, which would support printing hostnames or IP addresses, time
intervals, offsets, and all other data that need to be printed.
Depending on what output mode chronyc was running in, it would print
the labels, align the columns, print the values with units, print end
of lines, etc. All functions that implement the individual commands
would then be modified to use this new function.
I'm planning to look into this in the next few weeks. At this point
I'm mainly interested in adding the CSV format to allow easy parsing
in shell, but I think the Prometheus format could be added too.
Does this make sense?
