I can tell you that as I read them, they meant nothing and I know what
they mean. This is why:
2016-03-02 14:58:09 EST [14366]: [8-1] LOG: could not resolve
"localhost": Name or service not known
2016-03-02 14:58:09 EST [14366]: [9-1] LOG: disabling statistics
collector for lack of working socket
Why would I care about a "LOG" message. Generally speaking they don't
tell us anything useful. If, it was:
ERROR: could not resolve "localhost" ...
ERROR: Disabling statistics collector ....
It would mean a whole lot more. The second set makes sense to me but
what isn't clear is that the first one is really an error that can cause
the warnings of the second.
I do think that it should be an error if we are disabling statistics due
to something being wrong. We can't really operate properly without them.
Sincerely,
JD
