Hi Suhag, While you can use any string for the host address you can then only use check plugins that will handle multiple addresses. The SMTP plugin you are using does not seem to handle the comma seperated list, hence your error. The concept that a host is a host and not a network or subnet of hosts still holds true. In my opinion, Nagios is an open box of tricks, so it is very 'hackable' as to what you can do. You will therefore see a lot of documentation and tips about being able to do things in an unexpected way. You should bear in mind that hacking around may lead you into problems that you will generally have to solve yourself. If you're not sure what's going on in the background then I would recommend writing individual host definitions for your hosts and generally keep to the examples and way of doing things that you see in the example configuration files and other documentation. To fix your problem with the SMTP service in particular would be to write a wrapper script for the SMTP plugin to run it twice or more times (once for each host in the comma seperated list) and generate critical errors when the service is down on all hosts and warnings when the service is down on one or more hosts, or even generate perf data to say how many hosts have the service up/down. Of course, that would just be for one type of implementation and may not suit your needs. How you do that is down to you, and there may well be tools to assist you on www.nagiosexchange.org in that. However, you will not be able to 'just' add a PING or other service check to that host in the future, as you have 'hacked' the address entry in the host definition to specifically only work with your wrapper, or other plugins that support that. Hope that clarifies things a little. Thanks Giles ______________________________________________________________________ This email has been scanned by the MessageLabs Email Security System.
