The following updates were released to the Kentik platform for Synthetics during October 2026.
Features
Metrics tab on test results: Ping, DNS, HTTP, page load and throughput tests get a Metrics tab with collapsible time-series charts. A new filter bar (source agent, target or resolver, site, ASN, label) is shared with the Traceroute tab. The Agent results page also shows these charts. Status-code charts now summarize with max instead of average. Available to users with the embedded_ude permission.
Default lookback scales with test frequency: The default time range targets about 60 points. A 15 s test defaults to 15 m, and a 5 m test to 3 h.
Alerts Timeline column: The Tests table has a new default column next to Health Timeline. Each time bucket is colored by the worst alarm severity in it. Buckets before a test's creation, or while it is pending or paused, are grayed out. If alarm history is truncated, the tooltip says so.
Synthetics on Universal Agents is generally available: The "Enable Synth UA Capability" company permission is removed, so every company can run Synthetics on a Universal Agent.
Separate IPv4 and IPv6 static IPs: The agent's static IP setting is now split by IP family.
Site names in chart legends: Synthetics Site dimensions render as sites in UDE legends.
Bug Fixes
Dual-stack traceroutes: Traceroutes for URL and hostname tests are no longer pinned to one resolved IP, so dual-stack agents show both IPv4 and IPv6 paths.
Agent hardware swap: Swapping an agent now merges its metadata instead of replacing it, and keeps the deactivated agent's history.
Bulk delete: Bulk test deletion now validates IDs and enforces label permissions.
Preview tests: The Metrics tab and agent drill-down are hidden on preview tests
Terraform provider: Synthetics test settings are sent as objects, and unmanaged settings stay null on read.
Backend stability: Fixes for database connection handling in the Synthetics backend, with timeouts and a better health check.
