Error log monitor with SSH, Slack alerts & Jira ticket creation

Description

• Automates monitoring of error logs and notifies developers of critical errors.
• Sends Slack alerts for critical and non-critical errors, with auto-creation of Jira tickets for critical issues.

Essential Information

• Triggers manually or on a scheduled basis (e.g., every 5 minutes).
• Reads and parses server logs to detect errors.
• Alerts developers via Slack and creates Jira tickets for critical errors.

System Architecture

• Error Detection Pipeline:
  • Manual Trigger: Initiates the workflow manually.
  • Schedule Every 5min: Schedules automatic runs every 5 minutes.
  • Set Config: Configures basic parameters for log reading.
  • Read Error Logs: Executes SSH command to fetch server logs.
  • Wait For All Logs: Ensures all logs are read.
• Error Processing Flow:
  • Parse Logs: Parses logs and categorizes critical vs. non-critical errors.
  • IF Critical Error: Filters for critical errors.
• Alert and Ticket Creation:
  • Send Slack Alert: Sends detailed alerts for critical errors via Slack.
  • Create Jira Ticket: Creates a Jira ticket for critical errors.
  • Send Non-Critical Alert: Sends simple alerts for non-critical errors via Slack.

Implementation Guide

• Import the workflow JSON into n8n.
• Configure SSH credentials for log access.
• Set up Slack and Jira integrations with appropriate credentials.
• Test with a manual trigger and sample log data.
• Adjust the schedule (e.g., every 5min) and error parsing rules as needed.
• Monitor alert accuracy and ticket creation.

Technical Dependencies

• SSH access for reading server logs.
• Slack API for team notifications.
• Jira API for bug ticket creation.
• n8n for workflow automation and scheduling.

Customization Possibilities

• Adjust the Cron schedule for different intervals (e.g., every 10min).
• Modify Parse Logs node to refine error categorization rules.
• Customize Slack alert messages in Send Slack Alert and Send Non-Critical Alert nodes.
• Enhance Jira ticket details in Create Jira Ticket node (e.g., add priority).
• Add email notifications for additional alert channels.
