meow: Monitor Endpoints on (the) Web

meow is a simple monitoring system for unauthenticated HTTP endpoints.

Monitoring Murzik

meow consists of the following components:

  1. A configuration server to manage the endpoints to be monitored.
  2. The actual monitoring daemon performing the requests.
  3. An alerting server to notify endpoints that went offline (and back online).

Configuration Server (configCmd/config.go)

Run it with an existing configuration CSV file (to be overwritten):

go run configCmd/config.go -file sample.cfg.csv

A configuration defines multiple endpoints, each consisting of the following indications:

  1. Identifier: A (short) identifier string (matching regexp ^[a-z][-a-z0-9]+$)
  2. URL: The URL of the endpoint to be monitored.
  3. Method: The HTTP method to be used for the request (e.g. GET, HEAD).
  4. StatusOnline: Response HTTP status code indicating success (e.g. 200).
  5. Frequency: How often the request should be performed (e.g. 1m30s).
  6. FailAfter: After how many failing requests the endpoint is considered offline.
