Which of the following tools in Cumulus Linux is specifically useful for detecting and differentiating microbursts from regular network congestion?
Pick the 2 correct responses below
Monthly network utilization reports
ASIC monitoring with millisecond-level granularity
SNMP polling at 5-minute intervals
What Just Happened (WJH) feature for packet drop analysis
In Cumulus Linux, microbursts are short-lived, high-volume traffic bursts that often go undetected by coarse-grained monitoring like SNMP.
The two tools specifically used for this purpose are:
What Just Happened (WJH)
"WJH provides real-time packet drop visibility and classifies drops by reason (e.g., congestion, ACLs, etc.), enabling microburst detection."
ASIC monitoring at millisecond granularity
"Deep telemetry is enabled via the switch ASIC, which provides sub-second counters that capture microburst patterns otherwise missed by SNMP."
Incorrect Options:
A and C provide low-frequency sampling, insufficient for microbursts which last milliseconds.
