# cachet-monitor
|
||||||
|
|
||||||
|
Simple monitor to watch URLs (`HTTP`) or ports (`TCP`, `UDP`) and update Cachet status.
|
||||||
|
|
||||||
|
## Configuration
|
||||||
|
|
||||||
|
Example:
|
||||||
|
|

"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 * * * * *",
|
||||||
|
"offlineTimeUntilMajor": 300,

||||||
|
"api": "https://<cachet-url>/api/v1",
|
||||||
|
"token": "<user-token>"
|
