Hi all,
I’m trying to understand pre-authentication performance for our ServiceNow instance — specifically the time between a client’s initial request and the point where the login page or authentication challenge is returned.
I’m looking for guidance on any of the following:
Is there a supported way to measure pre-auth latency from within the platform?
Do Adaptive Authentication / Authentication Metrics expose timing or processing duration for pre-auth decisions?
Are there specific system logs, transaction logs, or events that can be correlated to calculate this server-side time?
Can this be surfaced via Security Center, Performance Analytics, or by exporting logs to a SIEM?
If deeper timing (per-policy evaluation, adaptive-auth steps, IP checks, etc.) isn’t directly available, is this something ServiceNow Support can expose or trace?
I’m also open to best practices from others who have measured:
End-to-end time to first byte (TTFB) on the login page
Internal policy evaluation time for pre-auth
Any recommended synthetic monitoring patterns for detecting pre-auth slowdowns
My goal is to get a reliable way to track and trend pre-auth performance so I can troubleshoot spikes or latency regressions.
Has anyone implemented this or found a reliable approach?
Thanks in advance for any insight!
