You can set your local timezone to look at the files in a sensible way. Everything is stored in UTC.
timedatectl list-timezones
sudo timedatectl set-timezone America/Los_Angeles
timedatectl status

You can see all the ‘units’ that you have using the following command.
If you don’t have your process running with a systemd
unit file, you won’t see it in this list.
Don’t fret, you can still see logs from those processes that are not managed by systemd
but that are still journaling.
systemctl list-unit-files --all | grep flow
flowmojo.com.service disabled
You can see here that my process is not enabled
to boot, but it will still log to the journal if it is started.
If you find the service listed in the unit files that systemd knows about, you can just look at the logs:
journalctl -u flowmojo.com.service [-f]
On systems that don’t have systemd
running the unit file you can lookup the executable:
journalctl _COMM=flowmojo.server [-f]

You can also pipe to jq
for maximum JS geekiness.
Reshaping your logs in to whatever you want.
journalctl -u flowmojo.com.service -f -o json-pretty | jq '{message: .MESSAGE, exe: ._COMM, service:.SERVICE, err: .ERR}'
