Logwatcher
HTTP log monitoring console program
Create a simple console program that monitors HTTP traffic on your machine:
- Consume an actively written-to w3c-formatted HTTP access log (https://en.wikipedia.org/wiki/Common_Log_Format)
- Every 10s, display in the console the sections of the web site with the most hits (a section is defined as being what's before the second '/' in a URL. i.e. the section for "http://my.site.com/pages/create' is ""http://my.site.com/pages"), as well as interesting summary statistics on the traffic as a whole.
- Make sure a user can keep the console app running and monitor traffic on their machine
- Whenever total traffic for the past 2 minutes exceeds a certain number on average, add a message saying that “High traffic generated an alert - hits = {value}, triggered at {time}”
- Whenever the total traffic drops again below that value on average for the past 2 minutes, add another message detailing when the alert recovered
- Make sure all messages showing when alerting thresholds are crossed remain visible on the page for historical reasons.
- Write a test for the alerting logic
- Explain how you’d improve on this application design
