Creating a fake, or combination, client

[Ward, Martin]

Hi all,

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.

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.

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).

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.

Thanks for your time,
