Thomas,

I had the same problem. I changed the following line in my hobbitgraph.cfg file and my graphs started working:

[mrtg] FNPATTERN mrtg.(.*).rrd # FNPATTERN mrtg.*\.([a-z0-9]+).rrd (original one)

Thanks, I've made that the default now.

Thanks, but I've tried and I still have no graph... Really don't understand, I'm using 4.1.2p1-1 version under debian, the rrd file for this host has data:

filename = "mrtg.master.eth0.rrd" rrd_version = "0003" step = 300 last_update = 1149241601 ds[ds0].type = "COUNTER" ds[ds0].minimal_heartbeat = 600 ds[ds0].min = 0.0000000000e+00 ds[ds0].max = 1.2500000000e+07 ds[ds0].last_ds = "345572533" ds[ds0].value = 1.5902884768e+05 ds[ds0].unknown_sec = 0 ds[ds1].type = "COUNTER" ds[ds1].minimal_heartbeat = 600 ds[ds1].min = 0.0000000000e+00 ds[ds1].max = 1.2500000000e+07 ds[ds1].last_ds = "345572533" ds[ds1].value = 1.5902884768e+05 ds[ds1].unknown_sec = 0 (...)

I've generated graph manually with this command: grunt:/var/lib/hobbit/rrd/master# rrdtool graph /tmp/AA.png -s e-24h --title="Network Traffic (MRTG)" -v "Bits/second" DEF:inbytes=mrtg.master.eth0.rrd:ds0:AVERAGE CDEF:in=inbytes,8,* DEF:outbytes=mrtg.master.eth0.rrd:ds1:AVERAGE CDEF:out=outbytes,8,* LINE2:in#00FF00:'eth0 inbound' GPRINT:in:'LAST: \: %10.1lf (cur)' GPRINT:in:'MAX: \: %10.1lf (max)' GPRINT:in:'MIN: \: %10.1lf (min)' GPRINT:in:'AVERAGE: \: %10.1lf (avg)\n' LINE2:out#0000FF:'eth0 outbound' GPRINT:out:'LAST: \: %10.1lf (cur)' GPRINT:out:'MAX: \: %10.1lf (max)' GPRINT:out:'MIN: \: %10.1lf (min)' GPRINT:out:'AVERAGE: \: %10.1lf (avg)\n' 497x221

and it works ! I join the graph file...

So, why do that's not working with the cgi ?

Is that a dump with rrdtool ? Doesn't look like it. You must save the MRTG data files in RRDtool format (a binary format) for Hobbit to recognize and graph them. The old text-file format used by MRTG is not recognized by Hobbit.

oh sorry, I've done «rrdtool info mrtg.master.eth0.rrd» to get these data. With «rrdtool dump» I get :

I can see that rrd file as data inside, but how can I debug why hobbit-cgi/bb-hostsvc.sh nor hobbit-cgi/hobbitgraph.sh generate corrects graphs ?

Try this on your hobbit server:

REQUEST_METHOD="GET"
SCRIPT_NAME="hobbitgraph.sh"
QUERY_STRING="host=YOUR.HOST.NAME&service=mrtg&graph=hourly&action=view"
~hobbit/cgi-bin/hobbitgraph.sh

I've just try:

grunt:/var/lib/hobbit/rrd/master# REQUEST_METHOD="GET" SCRIPT_NAME="hobbitgraph.sh" QUERY_STRING="host=master&service=mrtg&graph=hourly&action=view" /usr/lib/hobbit/cgi-bin/hobbitgraph.sh Segmentation fault

looking à cgierror.log (after launching the same command with strace): 2006-06-02 15:42:14 hobbitgraph xgetenv: Cannot find value for variable REQUEST_URI

...maybe I have to give hobbitgraph.sh another data ?

Add a REQUEST_URI="" to that command, then.

Yes, now it works... so here's the result: grunt:/var/lib/hobbit/rrd/master# REQUEST_URI="" REQUEST_METHOD="GET" SCRIPT_NAME="hobbitgraph.sh" QUERY_STRING="host=master&service=mrtg&graph=hourly&action=view" /usr/lib/hobbit/cgi-bin/hobbitgraph.sh Content-type: image/png Expires: Fri, 02 Jun 2006 14:02:39 GMT

Or Hobbit was compiled with the 1.0.x version of the RRDtool libraries, but your MRTG generates files with the 1.2.x version of RRDtool.

A lot of Linux distributions ship with RRDtool 1.0.x, and it causes all sorts of confusion if you compile Hobbit with the standard RRDtool and then have a hand-made installation of RRDtool 1.2.x. Check where you have an "rrd.h" file installed and where it came from (the 1.0.x or 1.2.x version - it says so at the top of the file). Try removing your 1.0.x version of RRDtool, and re-compile Hobbit with the full "./configure; make; make install" sequence.

Yes, I've just see that I have librrd0 under 1.0.49, used with hobbit since I installed it and librrd2 under 1.2.11 who comes with rrdtool install (done while trying to put mrtg graphs into hobbit).

So, I'll have to downgrade rrdtool.

Thanks for help

Chris,

I would recompile hobbit with the newer version of rrdtool vs. downgrading rrd.

rrdtool info mrtg.router.gi0_1.rrd | grep rrd_ver

rrd_version = "0003"

rrdtool -V

RRDtool 1.2.11 Copyright 1997-2005 by Tobias Oetiker <tobi at oetiker.ch> Compiled Fri Nov 11 18:44:49 CST 2005

So it does work with 1.2.11

I would keep that hobbitgraph FNPATTERN change as well (thanks Henrik for incorporating that into the new hobbit)

Yes I know that I could recompile to get hobbit work with 1.2.11 rrdtool version but I ain't got time to do it (that's why I didn't spend to much time for this problem). I'll wait, maybe next hobbit version will work with ?! :)

By the way, I still have something strange, IN and OUT datas are the same... I'll take a look at my mrtg config file and get back here if nothing get better.

Thanks
