This n8n workflow automatically monitors error executions of workflows within the platform and sends alerts to a designated Slack channel. The process is triggered on a scheduled basis (every few hours) to ensure prompt notification of issues. It retrieves all active workflows, checks their error logs within the last hour, and generates a tailored Slack message if errors are detected.
The workflow begins with a Schedule Trigger node that initiates the process at specified intervals. It then fetches all active workflows via the n8n API, looping through each workflow to analyze recent execution data. A script node filters executions to identify errors within the last hour, counting them and generating a notification message if errors exist. The message includes the workflow’s name, error count, and a button linking to detailed logs or related resources.
Finally, if errors are found, they are sent collectively to a Slack channel through a dedicated Slack node, alerting team members instantly to take necessary action. This setup is particularly useful for continuous monitoring, ensuring quick response to workflow failures without manual checks, thus maintaining system reliability and operational efficiency.
