A internet monitor/tester that will ping and do speed tests at intervals
After having many issues with ISPs not giving us the internet speed we were paying for and having too many outages, I decided to write some code to monitor our internet connection. The first version of InternetMon just logged all the data in a file for me to go through later, but eventually I added a graphs to make it easier to see when our internet was slower than it should be.
InternetMon pings a specified IP address and does a speed test at certain intervals which can be changed in config.json. The default is ping 1.1.1.1 4 times every 300000ms (5 minutes), and do a speedtest every 3600000ms (1 hour). All of this is logged in log.txt and also to a database.
InternetMon runs on port 5514. To access the graphs, use the following URLs (replacing ip with the IP address of the device you’re running InternetMon on):
By default, you will be shown the data from the past 24 hours. You can also add a query string to the end of the URL to get data from a different duration:
?h=2 will get 2 hours of data. You can change this to get up to 23 hours of data?d=5 will get 5 days of data. You can change this to get up to 29 days of data
