Are you saying that you run the same tests on multiple hosts and only one host in not showing data? Yes.
Does this mean they all share the same NCV configuration in hobberserver.cfg and the same graph definition in hobbitgraph.cfg? Yes.
What if you remove the rrd file and let hobbit create a new one, does that help? 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!

If this is correct, then it really points to something notgetting 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 dumptool 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... GLH

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 whereits data is not being shown in the graphs even though the data exists.
The machine in question's Hobbit clientsends 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 thevalues are accurate.
However, the graph that is displayedbelow 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 holeto me, can anyone suggest where I might look?
