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
apt update && apt install make g++ git
Clone with Git
First, set git to allow all certificates, and get the files using Git.
git config --global http.sslVerify false git clone https://gitlab.cosi.clarkson.edu/jared/manage2client.git
Optionally, re-secure the system by only accepting repos with certificates.
git config --global http.sslVerify true
Move the folder to the root.
mv manage2client /manage
Move the systemd service to the systemd serivces folder
sudo mv /manage/manage.service /etc/systemd/system/manage.service
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
Enable Systemd Services
sudo systemctl enable manage sudo systemctl start manage
Sit back and relax! It should show up on a running manage2server momentarily.
Installing Management Server
Start with an Arch VM
