SSL certificate expiration
An expired SSL certificate can cause havoc to sites and APIs. Odown performs a daily check on your certificate and can alert you X days before your certificate expires. All alert channels (e-mail, SMS, Slack, Webhook, etc.) can be used for this alert.
Create or pick an existing alert channel that your check subscribes to and enable SSL certificate expiration and set the day threshold to your preference. If you don’t have your alert channels set up yet, see Alert Channels.
You can create specific alert channels for certificate expirations and subscribe all monitors to that channel.
You can create multiple alert channels with different thresholds if you want to be alerted at various thresholds.
