<DIV>Hi Mark,</DIV> <DIV> I've been testing Nagios, with not a huge amount of servers, but doing some stress testing with pasive services pushing lots of service_checks_data to the central instance installed in a Xen VM, and nothing seems to be worrying about the VM performance.</DIV> <DIV> Hope it helps.</DIV> <DIV> Regards,</DIV> <DIV> </DIV> <DIV>Sebastian Ganame</DIV> <DIV> </DIV> <DIV class=MsoPlainText style="MARGIN: 0in 0in 0pt"><FONT face=Verdana>-----Original Message-----<BR>From: nagios-users-bounces@lists.sourceforge.net [mailto:nagios-users-bounces@lists.sourceforge.net] On Behalf Of Cook, Garry<BR>Sent: Jueves, 17 de Mayo de 2007 04:28 p.m.<BR>To: Frost, Mark {PBG}; nagios-users@lists.sourceforge.net<BR>Subject: Re: [Nagios-users] Nagios Server in a Virtual Machine?</FONT></DIV> <DIV class=MsoPlainText style="MARGIN: 0in 0in 0pt"><?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:p><FONT face=Verdana> </FONT></o:p></DIV> <DIV class=MsoPlainText style="MARGIN: 0in 0in 0pt"><o:p><FONT face=Verdana> </FONT></o:p></DIV> <DIV class=MsoPlainText style="MARGIN: 0in 0in 0pt"><FONT face=Verdana>I just answered a similar question on the smokeping mailing list.
