I don’t know of much of, if any, of an advantage to running multiple instances. The SMP will usually not help there because the other cores will be occupied executing plug-ins. If you had another box you could go with a distributed environment instead. Perhaps using SVN to keep record of config changes.<o:p></o:p> <o:p> </o:p> <div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0in 0in 0in'> From: shadih rahman [mailto:shadhin71@gmail.com] Sent: Monday, December 14, 2009 9:54 AM To: nagios-users@lists.sourceforge.net Subject: [Nagios-users] benchmark question<o:p></o:p> </div> <o:p> </o:p> List, Is there any information as to what is the maximum number of services one can run on a single box with single instance of Nagios? I did not find any concrete data on this. I am running a single instance of nagios on a quad core 2.5 GHZ machine with with 4 Gigs of RAM. I have total of 7359 service check running on this box. I have also ndoutils running on the same box as backend. My total service checks is going to five fold very soon with a lot of nrpe checks. Now, my question is should I run multiple instance of nagios on the same box or a single instance will be able to handle about 30000 service checks? I already tested a dev environment with multiple instance of nagios with some hacking to init.d script, it started and monitored fine. What would be the preferred method of running nagios, single instance on a box or multiple instance on a box when we are dealing with high number of service checks? Please comment on this.
