alert manager port changing not working

[chan Basha]

Hi,

I am unable to change alert manager default port

in alertmanager.service file, I config like

--web.listen-address=":9400"

but still it is running on default port :9093

please give some suggestions 

Thanks and Regards

Must be a basic system administration problem of some sort:

1. what does "ps auxwww | grep alertmanager" show?

2. did you remember "systemctl daemon-reload" after changing the .service file?

3. then did you remember to do "systemctl restart alertmanager?"

4. are you sure you're looking at the right .service file?
