X-EYE is a free and open source service for monitoring your cron jobs, background processes and scheduled tasks. Before adding Slack integration, please log into X-EYE:
After logging in, go to the Integrations page, and click on Add Integration next to the Slack integration.
Click on the "Add to Slack" button, and you should be on a page that says "X-EYE would like access to your Slack team". Select the team you want to add the X-EYE integration app to.
You should now be on a page that says "X-EYE would like access to TEAM NAME". Select the channel you want to post X-EYE notifications to.
That is all! You will now be redirected back to "Integrations" page on X-EYE and see the new integration!
