This project implements a proof of concept USSD application that allows System Administrators to check/monitor basic stats of their servers via their mobile phone.
At NNDI we like to play around with different technologies to see how far we can stretch them for innovative applications. USSD is an old-but-great protocol that's popular and serves a lot of applications in Africa including Mobile Money and Banking.
We decided to try using USSD for something atypical - a kind of IOT application;
perhaps you can call this a USSD of Things project. ;)
This project is intended to be used with USSD APIs provided by AfricasTalking - so you will need to get access to their services to run it behind an actual USSD Shortcode. However, you can run it locally and test it with dialoguss
Run it with the following command
$ go get -u "github.com/nndi-oss/ussd"
$ cd $GOPATH/bin
$ ./ussd -h "my.server.com" -bind "localhost:8000"The dummy server provides hard-coded results for all calls and doesn't actually read stats from the host machine. You can use this to test the server
$ go run main.go -h "my.server.com" -bind "localhost:8000" -dummy- Dial Short code (e.g.
*384*8327#)
