'''Management''' (manage2server) is a vm used for monitoring the status of VM's on other machines and the status of the hardware in the server room, ie. checking the CPU, RAM, and hard drive stats, among other configurable things.

Each computer in the server room that is configured sends data periodically to '''Management''' which will be shown in an uptime page on a webpage that can easily be used to determine system uptime and service uptime among other things.

Also, you can view COSI network stats at http://management.cosi.clarkson.edu/cacti with the csguest user (and default password)

=Installing Management Clients=

Required Software: Git, g++, make

On Debian:

<pre style="background-color:#ffcccc">
apt update && apt install make g++ git
</pre>

==Clone with Git==

First, set git to allow all certificates, and get the files using Git.

<pre style="background-color:#ffcccc">
git config --global http.sslVerify false
git clone https://gitlab.cosi.clarkson.edu/jared/manage2client.git
</pre>

Optionally, re-secure the system by only accepting repos with certificates.

<pre style="background-color:#ffcccc">
git config --global http.sslVerify true
</pre>

==Prepare files==

Move the folder to the root.

<pre style="background-color:#ffcccc">
mv manage2client /manage
</pre>

Move the systemd service to the systemd serivces folder

<pre style="background-color:#ffcccc">
sudo mv /manage/manage.service /etc/systemd/system/manage.service
</pre>

==Configure system==

If the hard drive you want to track is not /dev/sda1, select a different mount point to track in totaldisk.sh and useddisk.sh

If you want to have virsh, edit run.sh, and un-comment the line with virsh.sh

If you want to poll faster, change sleep from 30 to 5. Any faster, and the Linux scheduler will fall behind on busy boxes.

==Compile Management for your platform==

<pre style="background-color:#ffcccc">
make
</pre>

==Enable Systemd Services==

<pre style="background-color:#ffcccc">
sudo systemctl enable manage
sudo systemctl start manage
</pre>

Sit back and relax! It should show up on a running manage2server momentarily.

=Installing Management Server=

Start with an Arch VM

==Set Hostname==

Edit

<pre style="background-color:#ccccff">
/etc/hostname
</pre>

Clear the contents and enter this on the first line, and save

<pre style="background-color:#ccffcc">
management
</pre>

==Set Network==

Copy example ethernet-static to netctl folder

<pre style="background-color:#ffcccc">
cp /etc/netctl/examples/ethernet-static /etc/netctl/ehternet
</pre>

Edit

<pre style="background-color:#ccccff">
/etc/netctl/ethernet
</pre>

Clear the contents and set it to this:

<pre style="background-color:#ccffcc">
Description='A basic static ethernet connection'
Interface=ens3 # Make sure this is the interface or you won't have a network
Connection=ethernet
IP=static
Address=('128.153.145.62/24')
Gateway='128.153.145.1'
DNS=('128.153.145.3')
</pre>

=Objectives=

*Create a monitoring system that can monitor all of the servers, battery backups, network, and also some temperature sensors placed through the server room at strategic locations
*Notify computers of when to power down in a power outage
*Create API's that can be used to interface the management platform

==Plans==

*Split off Cacti VM
*Create network interface system
*Add a sensor network to the server room for temperatures
*Create other useful scripts for connecting to Management
