Are all the last_update values in status.dat always the same?

[Steven D. Morrey]

Hi All,

After Andreas explained the correct default behavior I looked in base/xsddefault.c
I found this on lines 443 & 499
		fprintf(fp,"\tlast_update=%lu\n",current_time);

Now  this is Nagios -2.7 the same one Cary is running.  We should probably check 2.12 and 3.x to make sure this isn't the case there as well.

Sincerely,
Steve

They're tracked separately per status object. If the times are all
the same, that could mean you've found a bug, or Nagios does something
that doesn't quite make sense to me. This is from looking at the
data structures for hosts and services. I haven't examined the code
that prints it all out.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
