Life Checker

Checks if server is alive via Head request.

Prerequisites

Update config.yaml and targets.txt to your needs.

Make sure your logstash instances are up and running, and able to receive json via http input.

Example logstash.conf input config:

input {
  http {
    port => 5044
  }
}

Usage

Note that if you run this script with targets.txt without modifying - it will consume around 1.5Gb RAM. And if a subnet is even wider than x.x.0.0/16 - the consumption will increase even more.

Shell

python main.py

Then check your log collector for results.

Docker

First build an image with docker build . -t checker.

Run docker run --rm --name checker -v $(pwd)/config.yaml:/app/config.yaml -v $(pwd)/targets.txt:/app/targets.txt checker
