With this tool you can easily add monitoring to any server in your network with SSH enabled. You can run it locally, or host it on a server and gather historical data over time.
It uses node.js, so it's extremely light weight, storing it's data in MongoDB. It runs remote bash script commands via simple-ssh to execute it's actions, offering the option to store your own custom scripts and run them at a configurable cadence.
The default scripts are:
- Disk usage is found via
df -lh | awk 'FNR == 2 {print substr($5, 1, length($5)-1)}' - RAM usage is found via
free | grep Mem | awk '{print ($3 / ($3 + $4)) * 100}' - CPU usage is found via
ps aux | awk {'sum+=$3;print sum'} | tail -n 1
The commands used and duration between checks are completely configurable to further allow you to tweak that delicate balance between the information you want and the server resources you need. You can even add your own scripts to run regularly and see further information about your data.
The data is displayed in chats using the angular directive for google-charts. You can display any data from scripts in graph form, as long as it returns a number. For this reason, you may want to do a bit of parsing with grep or awk or the like. If you keep the system running, then the historical data will create beautiful line graphs.
This is not only a great tool for monitoring, but also for running regular jobs. For example: you could run daily builds and return the percentage of code coverage.
If you are coding locally and want to deploy it, try grunt build and just copy the contents of the dist/ directory to where you want to deploy. To run the server with a minimal install on localhost:8080
export SSH_KEY="$(cat ~/.ssh/id_rsa)"
npm install --production
npm start --productionYes, there are other tools for monitoring, but I wanted something that
- I didn't have to install on every server, taking up resources
- Was super lightweight, using almost no resources itself
- Could run on a Raspberry Pi
MoreOn does all of that and more, so I just had to share it with the world. I have it running internally on a Raspberry Pi monitoring servers on my network, so I know it works. Let's see how you use it!
On a normal screen, it spreads out to display lots of data at once.
But thanks to bootstrap, it scales well and looks good on lots of screen sizes.
This tool is generated using yeoman with the generator-angular-fullstack. That means that building and testing is easy. Make sure you have MongoDB running and nodejs installed, and then:
git clone https://github.com/deltreey/moreon.git
npm install
# npm install -g bower # if you don't have it
bower install # only needed when pulling
# npm install -g grunt-cli # if you don't have it
grunt serveThen just let the server sit there while you change files, updating automatically. Please make sure jshint and the tests pass before you put in a pull request.
