Monitoring your services with Papertrail and Heroku

Recently I have noticed some problems with my Internet connection, sometimes it was completely unavailable. I concluded that I need some precise information about the outages, so I can talk to my ISP. As at the same time I learned about the Paper Trail service, I decided to use it in my setup. Other thing, that I wanted to learn was Heroku, so I gave it a try. Both services have some free tier, which is perfectly sufficient for my needs.

The architecture of my solution is as follows: I have local server running on Raspberry Pi (as mentioned in one of the previous posts about the online radio streaming). On this server, I have a Python script, running as a cron job every 10 minutes. This script sends simple log message to my Papertrail account. Then, I have another Python script, that runs every 10 minutes as a scheduled job on Heroku. This script checks, if there are recent “heartbeat” logs on Papertrail and if not – sends an e-mail message. You can download the source code of both scripts from the github repository.
