Description

check_interv al 300s 60-120s Lower the interval to speed up fault detection proxy_hang_t ime 150s 60-120s Lower the Proxy hang determination time oc_hang_time 200s 60-120s Lower the OC hang determination time Assessed manually here: the benchmark check is environment-specific and cannot be evaluated reliably by a single command.

How it is checked

Audit method: Manual review

This recommendation cannot be checked automatically. A scan lists it with these instructions when you pass --include-manual.

Check check_interval (default 300 s), proxy_hang_time (default 150 s) and oc_hang_time (default 200 s) in manager.json. Values must be aligned with the business SLA (failure detection fast enough for the required RTO); values longer than the SLA allows are a finding.

How it is fixed

Fix method: Guidance or infrastructure patch

Adjust the health check interval according to SLA requirements: Parameter Defau lt Recommend ed
