Why is Splunkd not starting after a reboot, wih Systemd enable-boot start?

We setup splunkd to autostart using systemd.
-> https://docs.splunk.com/Documentation/Splunk/latest/Admin/RunSplunkassystemdservice

but when the linux server reboot, we did no see Splunkd starting, we had to manually start it.

TL;DR : you need systemd setup AND splunkd service enabled for it to kick in.

____

1) Check if you have the systemd script setup :
/etc/systemd/system/Splunkd.service

2) check if the Splunkd service is enabled

systemctl status Splunkd

when it's enabled and started, you will see

If it's disabled and not started you will see

if it's disabled but was manually started you will see

if you do not see it enabled, enable it

systemctl enable Splunkd

Then it should autostart when you reboot your server.
