Be sure to replace the Mikrotik IP & the DHCP network (see line 8, "network set #")

Mikrot IP: 192.168.88.1/24 DHCP network: 0

/tool fetch url="https://boot.netboot.xyz/ipxe/netboot.xyz.kpxe"
/ip tftp add ip-addresses=192.168.88.0/24 req-filename=netboot.xyz.kpxe real-filename=netboot.xyz.kpxe allow=yes read-only=yes
/ip dhcp-server network set 0 next-server=192.168.88.1 boot-file-name=netboot.xyz.kpxe

Read the fan speed mode:

ipmitool -H <IP> -U <USER> -P <PASSWD> raw 0x30 0x45 0x00

The values are:

Standard: 0
Full: 1
Optimal: 2
Heavy IO: 4

Introduction

I often find myself ssh'ing into my servers and checking my systemd service logs with $ journalctl -f -u {name}.service. One day I got tired of this and wanted all of my important logs in once place (Amazon AWS Cloudwatch). To my dismay, there weren't any real good tutorials on how to do so. So, voilà.

Steps

Overall, it's a fairly simple process consisting of the following few steps.

1. Modify the service file

Open the service file with $ sudo vi /lib/systemd/system/{name}.service

Modify the [Service] section:

on linux 4.19, I get

error creating new backup file '/var/lib/dpkg/status-old': Invalid cross-device link

when trying to install stuff on a ubuntu docker container. this seems to be an issue with metacopy https://www.spinics.net/lists/linux-unionfs/msg06109.html

issue can be worked around by running

	{
	# minimized for clarity.
	# Some of these might not be needed. After some trial and error
	# I got this working with these configs.
	# I do not have the patience to rn an elimination test.

	services.gnome.gnome-remote-desktop.enable = true;

	# Enable the X11 windowing system.
	services.xserver.enable = true;
