It must fail the number of times in a row you choose.\u003c\/p\u003e\u003ch4\u003eDoes it monitor my n8n server itself?\u003c\/h4\u003e\u003cp\u003eNo. It runs on your n8n, so if n8n is down it can't send. Pair it with an outside check for the server it runs on.\u003c\/p\u003e","brand":"Halter Home Labs","offers":[{"title":"Standard","offer_id":53118090412344,"sku":"uptime-monitor-alerter-standard","price":29.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1020\/3578\/3992\/files\/uptime-monitor-alerter.png?v=1791579621","url":"https:\/\/shop.halterhomelabs.com\/products\/uptime-monitor-alerter","provider":"Halter Home Labs","version":"1.0","type":"link"}
