Re: [Devmon] Feedback on v0.3 final

[xbgmsharp <xbg...@gm...>]

Hello,

I did get the same problem, plus one :)

I upgraded devmon from v0.3 beta4 to v0.3 final

About
# This is also used by the bb-hostsvc.cgi script to determine if the detailed
# status view of a test should include a graph.
TEST2RRD need to be set like this TEST2RRD="if_load=devmon"

But if you do that you don't get the graph in the status page only in  
the trends pages.
TEST2RRD="if_load"

You will get it in the trends and status but it doesn't graph anymore.

As anyone get the same problem?

Regards

I don't see the point of changing this parameter as it doesn't about  
hte documentation.
# BBTYPE: Determines how devmon will format its output pages.Accetable values
# are 'bb' or 'hobbit', either each option setting the output format to that
# of its respective server type [DEFAULT: hobbit]
