At a glance

p99 Latency is a performance metric tracked from Pingdom data. It surfaces operational signal at the performance layer so merchants can spot regressions, opportunities, and structural patterns in their store performance. The card pairs with sibling metrics in the Performance category to build a complete diagnostic picture; cross-reference the related cards listed below for context.

Calculation

Calculated automatically from your Pingdom data. See the At a glance summary above for what the metric tracks and the worked example below for a typical reading.

Worked example

A representative reading of p99 Latency for a typical merchant on Pingdom. The card reports the current period value alongside a comparison against the previous period. Direction matters: rising values may be healthy or concerning depending on the underlying metric. Cross-reference the siblings below to triangulate cause when the value moves outside expected range. For deeper investigation, use Vortex Mind to trace upstream causes; for natural-language exploration, ask Ask Viq.

Reconciling against the vendor’s own dashboard

Where to look in Pingdom’s own dashboard: The Pingdom dashboard surfaces this metric (or its components) under the relevant report section. Confirm period boundaries and filter settings match the Vortex IQ profile to reconcile cleanly. Why the Vortex IQ value may legitimately differ: Cross-connector reconciliation: complement with sibling cards in the same category for the full diagnostic picture. For divergence investigations, use Vortex Mind.

Known limitations / merchant FAQs

Q: How often does p99 Latency update? The card refreshes on the standard data refresh (typically every 30-60 minutes for live integrations). For real-time signals, force a manual refresh from the dashboard. Q: Why does my Pingdom dashboard show a different number? The most common reasons are period-boundary differences (Vortex IQ uses 30-day rolling vs vendor’s calendar months), time-zone alignment, and filter scope (profile-level vs vendor’s all-account view). Match these settings before assuming a real divergence. Q: How does p99 Latency relate to other performance metrics? Track this card alongside the siblings listed above to build a complete picture. Single-metric reads can mislead; the diagnostic value is in the cross-reference. Q: Can I customise the alert threshold? Yes, alert thresholds are configurable per profile in the Alert Rules tab. Adjust to match your business baseline rather than relying on the generic default.
