Yesterday I demonstrated goal services to you with the build-in goal services. But perhaps you have multiple important applications running on your system and you want to monitor them independently. How can you do that? Well, it’s simple: Create your own goal service!
It starts with the creation of a plain and simple SMF service. The easiest way to do so is using svcbundle.
root@testbed:~# LANG=C svcbundle -i -s service-name=milestone/myfirstgoalservice -s start-method=":true"
Waiting for milestone/myfirstgoalservice to reach online state.
It is safe to interrupt.A goal server doesn’t start applications. So can simply use :true as a start method. Right after executing the comand, you should see a running SMF service.
root@testbed:~# svcs milestone/myfirstgoalservice

root@testbed:~# svcadm disable milestone/myfirstgoalservice
root@testbed:~# svccfg -s svc:/milestone/myfirstgoalservice:default setprop general/goal-service=true
root@testbed:~# svcadm enable milestone/myfirstgoalserviceNow you can use the newly minted goal service. Like with the default goal service you can use the goals subcommand. However, you have to specify the goal service you want to configure. Otherwise it would modify the default service. You can specify the goal service with -g.
Okay, I’m a little bit lazy. I will just use sendmail and apache24 in my goal service. Thus both goal services will monitor the same services. Of course you could chose other services.
root@testbed:~# svcadm goals -g svc:/milestone/myfirstgoalservice:default apache24 sendmailNow we check the the goal service functionality by disabling one of the monitored services.
