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).
No, not if you:
1)Have "multi" definitions for the graph you want
2)You specify multiple server names in the graph url, or use the
Reports->Metrics Report feature. I prefer adding the server names in the
graph url, as I can reload it to have it update (whereas using the Metrics
Report requires you to go back and select a new date range).
You may want to try this with one of the existing tests that has "multi"
support, mem, cpu have them by default.
