May 2026 - Alerting

The following updates were released to the Kentik platform for Alerting during May 2026.

Features

Bulk acknowledgment comments: Added support for bulk ack comments, default sorting of comments by newest first, and a clearer "send" submission icon.
Synthetics notification preview: Synthetic alarm notifications can now be previewed by ID, letting users test notification templates before deployment.
Cloudflare API Token authentication: CFMT mitigation platforms now support API Token authentication in addition to API Key, with conditional field requirements and format validation.
compactJSON template function: The compactJSON function is now registered in the template editor as an alias for uglifyJSON for use in custom notification payloads.
Notification preview with real alarm data: Notification channel preview and test endpoints can now use real alarm data by passing an alarmID.
New count metric for policies: Policies can now use a new "count" metric that counts messages/flows matching policy conditions.
Device tags in alert policies: Policies can now use device tags in dimensions, device selectors, and filters; tags appear in supported-dimension and display-name API responses.

User-friendly alert clear reasons: Updated alert clearance messages to be more user-friendly and understandable.
Alerting table filter fixes: Fixed the persistent "Reset to Default" button and restored search terms from the URL on page load.
Policy name length validation: Flow policy names are now validated to the 50-character API limit to prevent rename errors.
Rolling window / toggle mode lock: Users can no longer switch existing policies between rolling window and toggle mode, ensuring mode consistency.
Syslog/SNMP traps policy validators: Fixed validation errors when creating Syslog/SNMP traps alert policies in the policy drawer.
Device Alerts tab loading: Reduced device alert lookback from 30 days to 24 hours to prevent the Alerts tab from timing out.
CFMT email validation: The Account Email field now requires a valid email format when using API Key authentication.
Flowspec rate limit rounding: Rate-limit values are now rounded to prevent route flaps and mitigation failures.
