  • Monitoring home internet speeds with Smokeping and Speed Test

    I’ve been monitoring my home internet’s uptime using Smokeping docker container for awhile now. But after finally switching from ADSL to a 100Mbps connection I thought it would be a good time to start also monitoring internet speeds.

    Turns out there is an existing plugin, smokeping-speedtest for Smokeping which does the job.

    For easy setup, I created a docker image to combine the plugin and it’s dependencies and with linuxserver’s docker-smokeping image as a base.

    For configuration, I just followed the instructions and added the follwing to the Probes file.

    + speedtest
    binary = /usr/local/bin/speedtest-cli
    timeout = 300
    step = 3600
    offset = random
    pings = 3
    ++ speedtest-download
    measurement = download
    ++ speedtest-upload
    measurement = upload

    I also added a new section to my Targets file to perform speed tests against a local ISP.

    + SpeedTest
    menu = Speed Tests
    title = Speed Tests
    ++ download
    menu = Download
    title = Download
    probe = speedtest-download
    server = 2173
    measurement = download
    host =
    ++ upload
    menu = Upload
    title = Upload
    probe = speedtest-upload
    server = 2173
    measurement = upload
    host =

    The complete Dockerfile is on github and the image on Docker Hub.

  • Moving from Heroku to Dokku

    With Heroku's recent changes to their plan offerings, my hosting costs were suddenly about to increase form $0 a month to $42. To run an app 24 hrs a day, you need to be on the hobby tier ($7/month). Not really happy with that, I decided to look elsewhere.

    I had previously explored Amazon's elastic beanstalk PaaS, but this time around I wanted to try hosting my own PaaS. Dokku bills itself as being a "Docker powered mini-Heroku in around 200 lines of Bash". After reading good things about it, I decided to give it a shot on a Digitial Ocean dropet.
