Forecasts combine linear and superlinear models, with yearly seasonality for scopes holding at least two years of usage history. Compute usage is available at P50, P75, and P99 percentiles; Cloud Storage bucket usage is shown at P100 only. Historical usage spans up to two years, forecasts up to six months, and historical forecast snapshots up to one year. Usage is sampled every five minutes and displayed within 24 hours; Overview insights refresh at least every 48 hours. Data can be exported as CSV or through the REST API to Cloud Storage or BigQuery.

It is in Preview under Pre-GA terms, may have limited support, and some organizations may need to request access.

Kentik Network Capacity Planning is a cloud service for network and infrastructure teams planning bandwidth across interfaces, WAN links, data centers, and cloud interconnects. It reports link capacity, utilization, and performance, then uses SNMP interface metrics and historical traffic to forecast daily bandwidth needs and project link runout. Automatically generated baselines help reveal unusual traffic and bandwidth hogs. Kentik correlates SNMP with NetFlow, sFlow, IPFIX, and BGP routing context, with visibility across data centers and AWS, Azure, Google Cloud, and Oracle Cloud Infrastructure. Forecasts support WAN right-sizing and connectivity cost planning. Custom thresholds and automated notifications can warn before overload causes downtime. Integrations include Slack, Microsoft Teams, PagerDuty, ServiceNow, and the listed cloud providers. The SaaS-native product offers API and web access. A 30-day trial is available; Pro starts at $2,000 per month billed annually, with 50 users and stated retention periods.
