This guide describes the necessary installation and configuration steps needed to configure OSS Grafana OnCall.

The intended audience for this guide includes:

  • Grafana open source admins who are responsible for deploying and configuring Grafana OnCall.
  • Grafana open source users who need to configure SMS and phone notifications using Grafana Cloud.

Configure Slack for Grafana OnCall OSS

The Slack integration for Grafana OnCall leverages Slack API features to provide a customizable and useful integration. Refer to the following steps to configure the Slack integration:

  1. Ensure your Grafana OnCall environment is up and running.

  2. Grafana OnCall must be accessible through HTTPS. For development purposes, use localtunnel. For production purposes, consider establishing a proper web server with HTTPS termination. For localtunnel, refer to the following configuration:

# Choose the unique prefix instead of pretty-turkey-83
# Localtunnel will generate an url, e.g. https://pretty-turkey-83.loca.lt
# it is referred as <ONCALL_ENGINE_PUBLIC_URL> below
lt --port 8080 -s pretty-turkey-83 --print-requests
  1. If using localtunnel, open your external URL and click Continue to allow requests to bypass the warning page.

  2. Create a Slack Workspace for development, or use your company workspace.

  3. Go to https://api.slack.com/apps and click Create an App .

  4. Select From an app manifest option and select your workspace.

  5. Replace the text with the following YAML code block . Be sure to replace <YOUR_BOT_NAME> and <ONCALL_ENGINE_PUBLIC_URL> fields with the appropriate information.
