1.1 Workflow description

Title: Prevent simultaneous workflow executions with Redis
Workflow name: Prevent simultaneous workflow executions with Redis

Purpose

This ensures that executions of scheduled workflows do not overlap when they take longer than expected.

How it works

This is a separate workflow which monitors the execution of the main workflow
Stores a flag in Redis (key dynamically named after workflow ID) which indicates if the main workflow is running or idle
Only calls the main workflow if the last execution has finished

Setup

Update the credentials suitable for your Redis instance
Replace the Schedule Trigger of your main workflow by an Execute Workflow Trigger
Copy the workflow ID from the URL
Paste the workflow ID in the Execute Workflow Node of this workflow
Configure the Schedule Trigger Node

5. General Notes & Resources

Review imported nodes carefully before activation. This catalog entry is intended to help you inspect the workflow structure, understand required services, and find related templates faster.

Node names, credentials, schedules, webhook paths, and external service limits may need adjustment for your workspace.

Monitor multi-city courier weather risk with Open-Meteo, GPT-4o, Gemini and Slack

## Quick overview This workflow checks 48-hour forecasts from Open-Meteo for multiple cities on a 6-hour schedule or via an on-demand n8n form, scores conditions against courier-impact thresholds, uses OpenAI (with Google Gemini fallback) to draft Slack-ready alerts, and posts operational updates to a Slack channel. ## How it works 1. Runs every 6 hours on a schedule or starts from an Operations Manager on-demand n8n form submission. 2. Builds a city configuration (all cities for scheduled runs, or a single selected city for on-demand runs) and constructs the Open-Meteo forecast API request. 3. Fetches a 48-hour hourly forecast from Open-Meteo and continues even if the request fails. 4. Scores each city’s forecast against rain, wind, snow, and heat thresholds across multiple time windows, applies 18-hour deduplication for scheduled runs, and flags any city feed failures. 5. Sends the alert candidates to OpenAI to generate a three-sentence, operations-focused message per city (using Google Gemini as the model fallback if configured). 6. Formats each alert as a Slack Block Kit message and posts it to the #ops-weather-alerts channel, and separately posts a Slack error notice if one or more city forecasts could not be fetched. ## Setup 1. Add an OpenAI API credential (used to write the Slack alert messages). 2. Add a Google Gemini (PaLM) API credential if you want the configured fallback model to be available. 3. Add a Slack OAuth2 credential and set or create the target channel (ops-weather-alerts / #ops-weather-alerts) in your Slack workspace. 4. For on-demand checks, share the n8n form URL with your team and update the city dropdown options and the city configuration code if you add or rename cities. 5. Review and adjust the per-city weather thresholds in the city configuration to match your courier operations risk tolerance. ## Requirements - OpenAI API key (GPT-4o / gpt-4o-mini) - Slack OAuth2 credential with chat:write scope - Google Gemini API key (optional, for AI fallback) ## Customization - Add or remove cities by editing the CITIES array in the City config node, no other nodes need to change. - Adjust URGENT/HEADS_UP score thresholds in the Score + dedup node to raise or lower sensitivity per city. - Change the delivery peak windows (default 11:00-14:00 and 17:00-22:00) in the same node to match your market hours. - Swap the Slack channel name in both Slack nodes to route alerts to a different channel. ## Additional info This workflow was built and tested on a self-hosted n8n instance (Oracle Cloud A1 Flex, Ubuntu 24.04) and is fully compatible with n8n Cloud. Weather data is sourced exclusively from Open-Meteo (open-meteo.com), an open-source weather API requiring no authentication. Forecast accuracy follows Open-Meteo's standard model ensemble — verify critical alerts against local meteorological services before operational decisions. Deduplication uses n8n workflow static data (global scope). Clearing static data manually or migrating the workflow to a new instance will reset the deduplication state, causing the next scheduled run to re-evaluate all cities as if no prior alerts have been sent. The GPT-4o prompt includes city-relative climate context so the model understands that an alert in Nairobi means sustained flooding rain, while an alert in Helsinki means genuinely exceptional conditions beyond the Nordic baseline. This prevents generic alert copy across climatically different markets. The form trigger is designed for Operations Managers with no technical background — no n8n access required. Share the webhook URL directly and they can force an immediate check from any browser. Peak delivery windows (11:00-14:00 and 17:00-22:00 local time) are used to escalate severity scoring during high-order-volume periods. Adjust these in the Score + dedup node to match your market's actual peak hours.

Notify website downtime via email and Telegram alerts

## Quick overview This workflow runs every minute to check one or more website URLs with HTTP requests and, if a site appears down on two consecutive checks, sends an email alert and a Telegram message. ## How it works 1. Runs on a schedule trigger every minute. 2. Loads a newline-separated list of website URLs plus alert settings (wait time, Telegram chat ID, and email address), then converts the URL list into an array. 3. Splits the array to test each website individually with an HTTP request that captures the full response without failing the workflow on errors. 4. Determines whether the site is up based on the HTTP status code (up if status code is 400 or lower). 5. If the first check indicates the site is down, waits for the configured number of seconds and performs a second HTTP check for the same URL. 6. If the second check also indicates the site is down, sends a “Website Down” email via SMTP and then sends a Telegram message to the configured chat. ## Setup 1. Add SMTP email credentials (for example, Gmail SMTP on port 465) and set the from/to email addresses in the email step. 2. Create a Telegram bot with BotFather, add Telegram Bot API credentials in n8n, and set your Telegram chat ID in the workflow configuration. 3. Update the website URL list and the wait time (seconds) in the workflow configuration to match the sites you want to monitor and your preferred retry delay.

Route CI/CD failure alerts with OpenAI, Slack, Linear, Sheets and Gmail

## Quick Overview This workflow receives CI/CD failure webhooks, classifies severity by branch, uses OpenAI to generate a root-cause diagnosis and remediation, then alerts Slack, creates a Linear issue, logs the incident to Google Sheets, and emails a summary via Gmail. ## How it works 1. Receives a POST webhook from your CI/CD system with pipeline run status and metadata. 2. Parses the payload to extract status, pipeline name, branch, commit details, error log, and run URL, and drops malformed events. 3. Filters out non-failure runs and assigns a severity level and Linear priority based on the branch. 4. Sends the error log and context to OpenAI to return a JSON diagnosis, remediation step, and rollback recommendation. 5. Posts a Slack alert to the on-call channel for Critical incidents and posts all incidents to a developer Slack channel. 6. Creates a Linear issue with the failure context and AI diagnosis, appends the incident to a Google Sheets log, and emails a Gmail HTML summary to the engineering lead. ## Setup 1. Copy the workflow’s webhook URL and configure your CI/CD platform (for example GitHub Actions, GitLab CI, or CircleCI) to POST failure events to it. 2. Add credentials for OpenAI, Slack, Google Sheets, and Gmail, and provide a Linear API key for the Linear GraphQL request. 3. Replace placeholders for Slack channel IDs, Linear team ID, Google Sheets spreadsheet ID and sheet name, and the engineering lead email address.
