cachet-monitor

Simple monitor to watch URLs (HTTP) or ports (TCP, UDP) and update Cachet status.

Configuration

cachet-monitor can monitor a list of services. Therefore it requires to setup all services in ./data/config.json. The id of each service has to match the cachet component id you want to update! You also can specify a custom timeout in seconds for each service. If the service timeout is passed the status will be SLOW (Cachet Performance Issues).

You also need to specify the interval (cron) your services should be checked. You can use the cron syntax from node-cron. You also have to set offlineTimeUntilMajor which is the offline time in seconds until the state of an offline service turns from partial to major outage. Finally you need to provide the information to your cachet instance (api and token). The "global" timeout value will be used as a final request timeout for each service. If the check request does not complete in this time the service will be marked as offline.

Example:

{
	"services": [
		{
			"id": 1,
			"type": "HTTP",
			"url": "https://sp-codes.de",
			"timeout": 60
		},
		{
			"id": 2,
			"type": "TCP",
			"host": "sp-codes.de",
			"port": 443,
			"timeout": 60
		}
	],
	"cron": "0 * * * * *",
    "timeout": 30,
	"offlineTimeUntilMajor": 300,
	"api": "https://<cachet-url>/api/v1",
	"token": "<user-token>"
}

Run with docker

You can use the docker image samuelph/cachet-monitor and mount a volume to /monitor/data to persist cache and config:

docker run -v /your/path/monitor/data:/monitor/data samuelph/cachet-monitor

You also can use it in docker-compose.yml:

services:
  monitor:
    image: samuelph/cachet-monitor
    restart: always
    volumes:
      - /your/path/monitor:/monitor/data
