Marc, Thanks for your reply. The reason behind doing multiple instance is described below. Thanks 1) Previous monitoring system (survivor) was running multiple instance based on different systems group. 2) I have been doing hostgroup and servicegroup along with contactgroup to represent different instances of previous monitoring system. However its growing exponentially and seeing performance issue. ( currently there are 8000 servicechecks. Some of the hosts will be 20 fold on the number of service checks run on them soon.) 3. Ndoutils database has performance on quering some of these services. When run different instances with separate database their data set will be smaller and it will be easy to retain the data for longer time. <div class="gmail_quote">On Fri, Oct 23, 2009 at 9:38 AM, Marc Powell <<a href="mailto:marc@ena.com">marc@ena.com</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> <div class="im"> On Oct 22, 2009, at 2:03 PM, shadih rahman wrote: > All, > I am sub dividing my nagios into multiple instances.

Nagios doesn't understand multiple arguments to things like 'log_file'. <div class="im"> > 3) Is there a possibility for namespace clash in cgi urls? </div>I'm not sure but you may have issues if you enable the use of nagios environment variables? 4) Why do you think you need to run multiple instances of nagios?
