I configured Papertrail, a log management add-on frequently used on Heroku, to send error log notifications to a Slack channel, so I’ll introduce the method.

Configuring Papertrail to Notify Specific Logs

Saving Specific Keyword Searches

First, search for specific keywords and save the search results.

Click the Save & Setup an Alert button to proceed with notification settings.

Selecting Papertrail Alert Notification Destination

You can configure alert notification destinations from the Create an Alert page.

Most major services are available, and you can choose from categories like Email, Chat, Monitoring & Notifications, Graphing & Metrics.

This time, I’ll select Slack and proceed with configuration.

Configuring Papertrail Notifications to Slack

Set up Papertrail app integration on the Slack side.

Specify the notification destination Slack Channel and click the Add Papertrail Integration button to proceed with configuration.

Once you get the Slack Webhook URL, copy it and return to the Papertrail configuration screen.

Configuring Slack Webhook URL in Papertrail

Save the Slack Webhook URL in Papertrail’s alert management screen.

Once configuration is complete, a page like the following will be displayed.

By utilizing Papertrail and Slack, we can now receive immediate notifications for only important error logs.
