knockNOC

knockNOC is a ping-based monitoring solution that does just what it says: pings endpoints and logs their response. It has a modifiable set of alerting metrics and is able to send alerts for non-response to a host of popular platforms.

Features

  • Monitor multiple endpoints (URLs or IP addresses)
  • Garbage "themes"
  • Pings
  • Configurable alerting system
  • RESTful API for ping data
  • Dockerized for easy deployment

Prerequisites

  • Docker
  • Docker Compose

Quick Start

  1. Clone the repository:
git clone https://github.com/N-Erickson/knockNOC.git
cd knockNOC

Modify the config.yaml file to add your endpoints and configure alerting (see Configuration section for details).

nano config.yaml

Build the Docker image:

docker-compose build

Start the application:

docker-compose up

Access the dashboard at http://localhost:5000

Configuration

Edit the config.yaml file to customize your endpoints and alerting settings. The file structure is as follows:

endpoints:
  - url: https://example.com
    display_name: Example Site
  - url: 192.168.1.1
    display_name: Local Router

ping_frequency: 60  # in seconds

alerting:
  enabled: false
  consecutive_failures_threshold: 3
  cooldown_duration: 300  # in seconds
  pagerduty:
    enabled: false
    api_key: YOUR_PAGERDUTY_API_KEY
    service_id: YOUR_SERVICE_ID
  opsgenie:
    enabled: false
    api_key: YOUR_OPSGENIE_API_KEY
  slack:
    enabled: false
    webhook_url: YOUR_SLACK_WEBHOOK_URL
  telegram:
    enabled: false
    bot_token: YOUR_TELEGRAM_BOT_TOKEN
    chat_id: YOUR_TELEGRAM_CHAT_ID
  discord:
    enabled: false
    webhook_url: YOUR_DISCORD_WEBHOOK_URL

Alerting Configuration

enabled: Set to true to enable alerting, false to disable.

consecutive_failures_threshold: Number of consecutive failures before an alert is triggered.

cooldown_duration: Time (in seconds) to wait before sending another alert for the same endpoint.

Each alerting service (PagerDuty, OpsGenie, Slack, Telegram, Discord) can be individually enabled or disabled.

Provide the necessary API keys or webhook URLs for the services you enable.

API

knockNOC provides a RESTful API for accessing ping data:

Endpoint: http://localhost:5000/api/pings Method: GET Response: JSON array of endpoint statuses and recent pings
