<DIV><SPAN class=975305915-06112007><FONT face=Arial color=#0000ff size=2>I
think the thing I am missing in your example (and in general to be
honest) is: What is the link between fake-host in the bb-hosts
file and [custom-postfix] in the hobbitgraph.cfg file?</FONT></SPAN></DIV>

<P><FONT face=Arial size=2>Hi all,</FONT> </P>
<P><FONT face=Arial size=2>I am a newbie to Hobbit and have inherited a
working system. I have a good idea of how it all hangs together but now I
want to produce certain graphs and cannot figure out how.</FONT></P>
<P><FONT face=Arial size=2>I have a cluster of mail servers that run
Postfix; each of these clients is monitored within Hobbit. In the Trends
link for each client I have graphs showing the various mail queues
(incoming, deferred etc) and this data is stored in RRD files on the Hobbit
server. </FONT></P>
<P><FONT face=Arial size=2>Is there a way within Hobbit of creating a false
or meta- client that can have a graph with data from all of these RRD files?
Particularly I would like a graph that has all the incoming mail queue sizes
on it with one line per server. I already have this information in lots of
different RRD files but would like to have them all in one graph. I can
create a graph outside of Hobbit to do this, but within the monitoring
system it restricts the RRD files it will display data from to those in the
data directory of the selected client (in the Trends link).

<DIV><BR>Hmm. You could probably create a host and set up a noconn test
to some random IP like <A href="http://10.0.0.1">10.0.0.1</A> (i.e. in
bb-hosts: <A href="http://10.0.0.1">10.0.0.1 </A>
fake-host # noconn). Regardless of what host (or fake host, if you
do that), you will need to create a new RRD trend to that host.<BR><BR>You can
create an RRD graph (by modifying hobbit-graph.cfg) that gets its data from
multiple RRD files. These files are usually created in a directory for
each host, and I don't know if you can just create a symlink to those or
not. But assuming that works, you should be all set in creating a single
graph that plots all the other data using a single scale. <BR><BR>I think you
would want to add the following to hobbitserver.cfg:<BR>GRAPHS="<whatever
is already there>,custom-postfix"<BR><BR>And then hobbit-graph.cfg would
look something like this:<BR>[custom-postfix] <BR> . . .<BR>
DEF:hosta:HostA.rrd:AVERAGE<BR> DEF:hostb:HostB.rrd:AVERAGE<BR> .

<P><FONT face=Arial size=2>I have tried creating a new client in the data
files ans symbolically linking the other RRD files into its data directory,
but cannot persude the graphs to appear in the trends web page. </FONT></P>
