Since I have only one (Ubuntu) server at home currently running as a PVR (personal video recorder) for recording TV shows from a OTA (over-the-air) antenna and Plex for viewing my content via the Roku (more on all that on a later post), I like to see what my server is doing as far as performance at a glance from time to time. Sure, top or htop will do the job but I want more. I get more from using Glances. You can get more information on the utility here.
I setup my server to run the web UI and launch at start. I created this script to easily deploy to any machine running Ubuntu. I included in the script to also create a systemd service so that it would start after each reboot. Here’s the script:
#!/bin/bash # This script will install the Glances monitoring tool and create # a startup service for the Glances web server. See 'glances --help' # for details # Update and install sudo apt update && sudo apt install -y glances sleep 3 # Change the startup switch from false to true sudo sed -i 's/false/true/g' /etc/default/glances sleep 3 # Create the systemd service sudo touch /lib/systemd/system/glances.service sudo bash -c 'cat <<EOF > /lib/systemd/system/glances.service [Unit] Description = Glances web server After = network.target [Service] ExecStart = /usr/bin/glances -w [Install] WantedBy=multi-user.target EOF' sleep 2 # Reload systemd sudo systemctl daemon-reload sleep 2 sudo systemctl enable glances.service sleep 2 sudo systemctl restart glances.service sleep 2 sudo systemctl status glances.service sleep 2 hostip=`hostname -I` echo echo "Monitoring of this server will be viewable at http://$hostip:61208" echo
I have a third monitor above my other monitors that has a Raspberry Pi 3 connected where I have my Glances page running.
Here is a closer look at the web UI.
It’s been very convenient to view during recordings so that 1.) I know when there is a recording and conversion of the video file going on by seeing a spike in CPU and memory and 2.) to see how well my machine performs during those recordings and conversions.
