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).
If you want to create a graph from multiple rrds, I would suggest using the 3rd party tool called drraw (http://web.taranis.org/drraw/).
