* We make extensive use of service -> hostgroup -> host mappings. * We use this for sets of services that are used by multiple 'customers' within our Nagios instance (not paying customers, more like project teams)
So this leads to a growing number of requests where our users want to have service groups to be able to control services associated with hostgroups but bounded by their local host groups. For example, we might have: * Net-SNMP hostgroup (net_snmp_hosts) * Net-SNMP services * Web server operational host group (web-server-ops) containing all web server hosts This group would want to be able to have a service group control for their hosts (web-server-ops) for the Net-SNMP services. Currently we have to do multiple members host/service_regex lists to do this, e.g. members www1.example.com,Net-SNMP.* members www2.example.com,Net-SNMP.* members www2.example.com,Net-SNMP.* So this means that: 1) We have to attempt to redo the hostgroup -> service mappings through regular expressions, which will work because we use consistent naming conventions for services associated with a hostgroup, but puts the burden on the user to update their files (or us) to keep in sync with host group -> service mappings, which will certainly lead to things getting out of sync 2) The user has to explicitly enumerate hosts when in 99% of our cases the user already has the hosts that have the services in a specific group, so again having to redo mappings that already exist. What would be ideal would be for the service groups to be either: * A tuple of host_group and service regex OR, better * A tuple of host_group and host_group where the second host group implies "all services associated with this host group" e.g. define servicegroup { alias Net-SNMP services on Web hosts servicegroup_name web_server_net_snmp members web-server-ops,net_snmp_hosts } Bam .. then any new services or hosts get added at start up time and the user has a very easy way to control specific groups of services bounded by their host groups with the control panel the CGI provides for service groups. i realize this is not a trivial thing to implement, so I am asking for feedback on 1) If others would find this useful 2) If so, what would be a preferred syntax to implement this? * Override the current functionality so that if a LHS or RHS of a members tuple doesn't match a host or service, host groups are assumed? * Add a new member that is optional to the servicegroup object for this functionality Most likely we will implement this internally as we will have lots of our users wanting it, so if people have desire for this we would certainly prefer to do it using a syntax and style that others would care about so we could contribute the functionality back to the community once it is stable and tested. - Max ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
