To see a list of all known upstart jobs and their statuses, use the following command:
$ initctl list ... console stop/waiting mounted-run stop/waiting acpid start/running, process 2927 checkfs.sh start/running checkroot-bootclean.sh start/running kmod stop/waiting mountnfs.sh start/running nginx stop/waiting plymouth-stop stop/waiting rcS stop/waiting ufw start/running ...
It will tell you for each job if it is stopped or started.
man initctl for more details.
