I modified the script as per your suggestion and saved the script to
"/usr/lib/nagios/plugins" as "check_reboot_required". I then went to
"/etc/icinga2/conf.d" directory and added a config file called
"reboot_required.conf" with the following in it.
apply Service "reboot_required" {
import "generic-service"
check_command = "reboot_required"
assign where (host.address || host.address6) && host.vars.os == "Linux"
}
I restarted the icinga2 service and checked the Icinga2 startup.log file and
found the following error
check_command = "reboot_required"
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
I don't believe I have the new script properly defined in Icinga2. I have been
reading the docs and don't see yet see the step(s) I have missed. I am new to
Icinga2.
