All of the hosts that I am monitoring have both IPv4 and IPv6 Addresses and proper DNS records. As an example, this is my current setup to monitor http:
apply Service "http_ipv4" {
import "generic-service"
check_command = "http"
vars.http_address = "$address$"
assign where match("*http_*", host.vars.services)
ignore where host.address == ""
}
apply Service "http_ipv6" {
import "generic-service"
check_command = "http"
vars.http_address = "$address6$"
assign where match("*http_*", host.vars.services)
ignore where host.address6 == ""
}
object Host "www.duenndns.org" {
import "generic-host"
address = "213.183.56.244"
address6 = "2a02:150:7:213:183:56:244:80"
vars.services = "http_"
}
This works really nicely, as long as IPs are static. Now I want to
monitor a few hundred DSL-Routers, where neither the IPv4 nor the IPv6
addresses are static. What is the suggested way to solve this problem? I
think adding a -4 or -6 flag to all icinga predefined checks would help,
then I could do the following:
apply Service "http_ipv4" {
import "generic-service"
check_command = "http"
vars.http_protocol = "ipv4"
vars.http_address = "$host_name$"
assign where match("*http4_*", host.vars.services)
}
apply Service "http_ipv6" {
import "generic-service"
check_command = "http"
vars.http_protocol = "ipv6"
vars.http_address = "$host_name$"
assign where match("*http6_*", host.vars.services)
}
object Host "dynamic-ip.duenndns.org" {
import "generic-host"
vars.services = "http4_ http6_"
}
I know that some checks already support -4 and -6, but is it planned to
add this to other checks as well?
