Services: server status collection server


Management (stat3) is a vm used for monitoring the status of hosts 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 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) in raw data at http://stat.cosi.clarkson.edu/data since Cacti broke (again)

Installing Management Clients

Required Software: Git, g++, make

On Debian:

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

Re-secure the system by only accepting repos with certificates.

git config --global http.sslVerify true

Prepare files

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

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

make

Enable Systemd Services

sudo systemctl enable manage
sudo systemctl start manage

Whitelist

Email dunbarj@clarkson.edu to get the server added to the whitelist

Installing Management Server

Start with an Arch VM

Set Hostname

Edit

/etc/hostname

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

management

Set Network

Copy example ethernet-static to netctl folder

cp /etc/netctl/examples/ethernet-static /etc/netctl/ehternet

Edit

/etc/netctl/ethernet

Clear the contents and set it to this:

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')

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

  • Update ALL instances of Management to stat3 when client completed (and depricate the old versions - we still have versions of Management 1.0 and manage2client out there)
  • Create new server with authentication (both real encryption and perhaps OpenComputers compatible for Minecraft servers :P)
 * Configurable low power options
 * Email Notifications
 * Shutdowns
  • Sensors Interface - configurability is a must
  • Better web interface? Cookies? Logins? LDAP? PAM?
  • Ability for custom messages, custom dashboards?
