When warnings arrive
A warning is news worth your attention while the target still works: a certificate or a domain that expires soon, an answer that got slow. A warning never opens an Incident, and it is never shown on a Status page.
A warning is never sent the moment it happens. It waits a little, so that everything that happened at about the same time arrives in one message to each Channel. How long it waits depends on the kind of news.
News of an expiry: once a day
Section titled “News of an expiry: once a day”These warnings are sent once a day, at 09:00 in the Project’s timezone:
- Certificate: expiring
- Domain: expiring
- Domain: registration unreadable
An expiry date moves by the day, so sending it sooner would tell you nothing new. The day’s message names each certificate or domain once, with its date and the Monitors behind it.
The Project’s timezone is the Timezone in Project settings, on the General tab.
A slow answer: within minutes
Section titled “A slow answer: within minutes”These warnings are sent 5 minutes after the first of them in the Project:
- Uptime: not answering over IPv6 or IPv4
- Performance: slow
A slow answer is news about now, so it does not wait for the next day. The wait gathers every Monitor that turned slow at about the same time, such as all the Monitors behind one slow server, into one message.
Each warning is said once
Section titled “Each warning is said once”We tell you about each warning once, and never again while it lasts.
- A certificate is said to expire soon once as it reaches each of 30 days, 14 days and 7 days before its expiry date.
- A domain is said to expire soon once as it reaches each of 30 days and 7 days before its expiry date.
- A slow answer is said once when it starts, however long it lasts, and so is a target that stops answering over IPv6 or IPv4. We say it again only after the Check has been fine for 20 minutes. So an answer time that keeps crossing your threshold is one message, not one each time.
During an outage
Section titled “During an outage”While a Monitor is down, its warnings wait until the outage is over, unless a rule has Send warnings during an outage turned on: see Notification rules. A warning that is no longer true when the outage ends is not sent.
Where warnings never go
Section titled “Where warnings never go”Warnings never go to a phone, by SMS or WhatsApp: a warning never spends a credit.
A Webhook does not wait: it gets each warning as it happens, in a request of its own. See Webhooks.
