[hobbit] Re: Hobbit server/client, Nagios server ?! (fwd)

[Martin Flemming]

Hi, Martin .. again :-) !

Thanks a lot for answer and your informations .. !!

.. for my apology and i think you notice it, i'm not knowledgeable 
with the nagios-working-model ...

> yes?

Not quite correct, also the Xymon-Server could trigger the 
Nagios-Server, like the xymon-alert-mail to myself ... :-)

Damned, once more my misapprehension again,
about  nagios ( not a client-server-application), sorry !

I believe, and the other thought, with xymon-server to nagio-server
is not easier i think ..

There was a nebulous idea, that Nagios can get a xymon-alert for 
a host (from xymon-client or from server), and if you "click" on the 
alarm-icon on Nagios, you will be redirect to the  xymon-page or subpage 
or host-info-page ...

And you describe this very intelligible with this below, thanks ! :-)

It seems ( this was apprehensive ) to be a bigger project :-(

Thanks a lot again for your answer !

.. but i still wonder, that i'm the only one, who wants/need this
connection between xymon and nagios ( ok, Xymon is the better  of 
application course, but nagios is more widespreaded , i think ...)

cheers,
