[op5-users] New to Op5 and Merlin

[Frater, Greg J]

Greetings All, 

I just joined the mailing list, primarily due to interest in your Merlin
and Ninja projects.  But first I wanted to say thanks to Op5 for the
Nordic Meet on Nagios.  I am from the US and was able to view many of
the video sessions online and learned a lot from the presenters.  Thanks
for putting the Meet together and for sharing the event with the rest of
us non Nordic folk. ;-)  I also like being able to put a face with the
emails that I read on the mailing lists. 

I do have questions about Merlin.  We are using NDO to support our
NagVis implementation and having intermittent troubles with it.  I think
the problems are related to MySQL performance but am pretty much a hack
when it comes to DBA work so I'm not sure.  I've done some tweaking to
the MySQL settings which made things better for a while.  In any case,
I'm thinking I need to find a better solution for NagVis and as I
understand it I can use either the ndo2fs and Merlin.  My question is in
regard to the stability of Merlin, would you say it's like alpha, beta
or production stable?  Also do you have any sense for server sizing to
support Merlin?  In our environment we have around 500 hosts and 5300
service checks, currently everything (Nagios, NDO database, NagVis,
etc.) are all running on a single box (2 CPU 2.6MHz, 4GB RAM), currently
the web interfaces all respond fine but we have a high check latency
(~90 sec for service checks).  What I want to know is at what point
would you recommend moving Merlin/MySQL to a dedicated server separate
from the Nagios server? 
Thanks again for the sharing the Nordic Meet videos and for your work in
this arena,
Regards,
-greg
