[Nagios-users] User-defined host/service attributes
Hi, recently, I was confused by my Nagios reporting a host DOWN event while the host was alive and kicking. After debugging for a while, I found out that the host had changed IP addresses and nagios was, of course, still checking the old address since it was configured to check the IP address. To catch such error situations earlier, I'd now like to have Nagios check that the host name indeed still points to the IP address we're actually checking. This is easy enough: define service { use my-service hostgroup_name hostnameip service_description my_hostnameip check_command check_hostnameip } define command { command_name check_hostnameip command_line $USER1$/check_dns --hostname=$HOSTNAME$ --expected-address=$HOSTADDRESS$ } This, however, means that one has to have the DNS name of the host in the host_name field: define host { use my-linux-host host_name ipdesc.iface.host.loc.mydomain.example hostgroups defaultping, snmp-w68, ssh, hostnameip alias foo server running bar and baz services, colocated in blu address 10.1.1.47 parents localhost } This is a bit clumsy since our host names are complicated and lengthy. I'd like to have something like define command { command_name check_hostnameip command_line $USER1$/check_dns --hostname=$CUSTOMATTR$ --expected-address=$HOSTADDRESS$ } define host { use my-linux-host host_name host.mydomain.example custom_attributeipdesc.iface.host.loc.mydomain.example hostgroups defaultping, snmp-w68, ssh, hostnameip alias foo server running bar and baz services, colocated in blu address 10.1.1.47 parents localhost } If this possible in Nagios2? If not, are there other ideas how to solve this? Greetings Marc -- - Marc Haber | "I don't trust Computers.
