RE: [hobbit] Graphs are missing data, but it's there!

Yes.

I did this and as you'd expect initially the web page showed no graph
although it did show data (stored from the previous run I presume).
 
After an interval the file appeared again but running "rrdtool dump" on
it STILL failed to produce any data.
 
I'm starting to wonder about the versions of RRD, but they ought to be
data-compatible; I'm using rrdtool v1.2.15.
 
The histlogs show no errors, the hist/mc25,... data file contains valid
data. I DO get a few RRD errors like this:
 
rrd-status.log:2008-07-21 09:46:19 RRD error updating
/opt/hobbit/data/rrd/mc25.lon.server.colt.net/tcp.smtp.rrd from
10.44.107.48: illegal attempt to update using time 1216633579 when last
update time is 1216633579 (minimum one second step)

which make it look like Hobbit is actually updating the RRD file... I
just can't get any data out!

	Are you saying that you run the same tests on multiple hosts and
only one host in not showing data? Does this mean they all share the
same NCV configuration in hobberserver.cfg and the same graph definition
in hobbitgraph.cfg?
	
	If this is correct, then it really points to something not
getting into the rrd file. As previously suggested, rrd dump is your
best bet at finding the problem here. What if you remove the rrd file
and let hobbit create a new one, does that help?

		You know the data exists because you used the rrd dump
tool to display it?
		 
		Is the graph simply not shown at all, or is there a
"hole" in the Web page where it normally would go?  ("show page source"
might have a clue).
		 
		Some ideas/shots in the dark:
		 
		a) check the logs
		 
		b) meticulously compare a "working" system to the
non-working system, and make sure that they really are identical.
		 
		c) look at the trends page for this host to see if the
graph is okay there...
		 
		Etc.  I am sure you know the drill -- a big pain to look
under every rock, but it has to be done...

			Thanks for the suggestion but that didn't work
(I guess you meant rrd).
			 
			Any other ideas?

				All, 

				I have a problem with one machine where
its data is not being shown in the graphs even though the data exists. 

				The machine in question's Hobbit client
sends five pieces of numeric data (email queues) and these are displayed
on the web page for this service:

				==== 
				Thursday July 24 11:29:11 UTC 2008 
				
				ActiveStatus:  green
<http://hbt0.lon.oss.colt.net/hobbit/gifs/green.gif> 
				ActiveQueue: 106
				ActiveTrend: tendency rising with -60
mails.
				BounceStatus:  green
<http://hbt0.lon.oss.colt.net/hobbit/gifs/green.gif> 
				BounceQueue: 58
				BounceTrend: tendency falling with 3
mails.
				DeferStatus:  red
<http://hbt0.lon.oss.colt.net/hobbit/gifs/red.gif> 
				DeferQueue: 150464
				DeferTrend: tendency falling with 95
mails.
				CorruptStatus:  green
<http://hbt0.lon.oss.colt.net/hobbit/gifs/green.gif> 
				CorruptQueue: 0
				CorruptTrend: amount equal to last
measure.
				IncomingStatus:  red
<http://hbt0.lon.oss.colt.net/hobbit/gifs/red.gif> 
				IncomingQueue: 247049
				IncomingTrend: amount equal to last
measure.
				
				 Deferred Queue is too high but is
decreasing already. 

				==== 
				These numbers change over time and the
values are accurate. 

				However, the graph that is displayed
below this data is blank. I have historic data, the files exist, and
what is more I have other machines that are configured identically to
this one where the data IS graphed correctly.

				Hobbit graphs are a bit of a black hole
to me, can anyone suggest where I might look?
