notification channels

A channel is a destination pngr delivers alerts to. Channels are scoped to an organization and shared across rules — configure a channel once, reference it from as many rules as you like. A rule decides when to notify; a channel is where the notification lands.

Step-by-step setup for each — including where to get a webhook URL or a Telegram chat ID — is in set up notifications.

self-contained vs platform channels

Most channels are self-contained: their config holds everything needed to deliver (a Slack/Teams webhook URL, a Telegram bot token, a generic webhook URL). Two types instead ride on a single platform-level provider account shared across the whole deployment, with the channel config holding only the destination:

  • email is sent through a platform email provider; the channel only stores the recipient address.
  • sms is sent through a platform Twilio account; the channel only stores the destination number.
note

Because email and SMS dispatch through platform credentials rather than the channel's own config, the test ping doesn't exercise them — the test only covers the self-contained dispatch path. If the platform provider isn't configured on the deployment, an email/SMS channel can still be created and listed, but delivery is a no-op that logs a failure.

credentials are write-only

Channel config is encrypted at rest. The list never returns it, and the single-channel view returns it with credential fields redacted to ${...} placeholders — only non-secret fields (the email recipient, a Telegram chat ID) come back in clear so an edit form can pre-fill them. You can't read a stored secret back out; to rotate one, type the new value and save, which re-encrypts the whole config blob.

test ping & enable toggle

  • send test ping delivers a real notification immediately, so you can confirm the destination works before you depend on it. Used during setup to validate the credentials. (Not available for email/SMS — see the callout above.)
  • enable / disable toggles a channel without deleting it. A disabled channel stays configured and attached to its rules but delivers nothing — handy for muting a noisy destination during maintenance.
