A NOC engineer needs interface utilization samples for two SD-WAN sites across a fixed six-hour maintenance window from last Tuesday, pulled in a single authenticated call to SD-WAN Manager. The request must pin the exact start and end of that window. Which statistics query body should the script send?
Select an answer to reveal the explanation.
Short Explanation
Treat the maintenance window like two bookends: your single authenticated POST should use an entry_time between rule with the exact UTC start and end, and select both sites. That way, you'll get the historical slice you need—not live counters, a rolling window, or separate per-site queries.
Full Explanation
Submit a query document to the interface statistics endpoint with an entry_time rule using the between operator and the window's UTC start and end, and a site-selection rule for both sites. A single authenticated POST can request matching records for that window across both sites; average utilization from the returned records. Real-time device-state routes report current state, not historical samples. A last_n_hours rule is relative to when the query runs, so it does not pin last Tuesday's window. Querying one site at a time requires multiple statistics requests, contrary to the single-call requirement. SD-WAN Manager, formerly vManage, has multiple generations of monitoring routes, so confirm the endpoint and query fields supported by your release.
