Check process running
This alert means that a process which should be running is not.
It’s likely that this process corresponds to a service, which you can check by looking in /etc/init or try running:
$ sudo service <process> status
This will also tell you the status of the service.
You can list all available services with sudo service --status-all.
If you cannot immediately find which service the process is corresponding to, it may be helpful to look through any
similar looking files in /etc/init, for example, the postgresql service runs the postgres process.
Often, it can be enough to just restart the service by using:
sudo service <service> start
If the service is referring to a GOV.UK application, it may be necessary to also restart the Procfile worker:
sudo service <service>-procfile-worker restart
If the process doesn’t correspond to a service then it will be necessary to find out more about how the process runs.
If the process doesn’t come back, then it’s more likely that there is something going wrong with it. You can start investigating by looking in the log files which could be in one of the following places:
/var/log/upstart/<process>.log/var/log/<process>//var/log/<process>.log
