Uptime Robot - Slack to Twilio SMS

Uptime Robot is a great monitoring service. They allow you to get notified via slack and email for free, but charge pretty heavily for SMS alerts.

This script can be used to send you SMS alerts via Twilio. To receive 100 alerts, it will cost you 75 cents from Twilio. Uptime Robot would charge $25.

You need:

• A Twilio account setup, with a purchased phone number ($1.00/mo)
• An Uptime Robot account setup.
• A Slack account and channel setup.

Installation (Debian/Ubuntu)

1. Clone this repo into your home directory.

2. Setup your SlackBot and give him a name: https://my.slack.com/services/new/bot

3. Open slack-uptime-robot.rb and update these variables with your own values:

   @twilio_sid = 'TWILIO_SID'

   @twilio_auth_token = 'TWILIO_AUTH_TOKEN'

   @twilio_from_phone = '+15125557890'

   @notify_phone = '+15125551234'

   @slack_token = 'SLACK_TOKEN'

4. open ubuntu-debian/etc/init/slack-uptime-robot.conf and update this path to the full path you are using: exec /path/to/slack-uptime-robot/slack-uptime-robot.rb

5. copy the file to /etc/init/slack-uptime-robot.conf

6. run service slack-uptime-robot start

7. Now, log into Slack, join the channel where you are receiving the UptimeRobot alerts, and type hi @SLACKBOT_NAME (replace SLACKBOT_NAME with whatever you named your robot). You should get a message saying that @SLACKBOT_NAME needs to be invited to the room, so click the link that will send him the invite.

8. Now you shoud see joined #channel by invitation from @yourname. Congrats, your bot is now in the room.

9. You can manually test the bot by typing Monitor is DOWN into slack and hitting enter. The bot should respond by saying I've sent a text to NOTIFY_PHONE. If so, congrats! You should receive the text.
