Fleet manages osquery agents with concrete mitigations: a process watchdog that blocks expensive queries for 24h, Linux cgroups as a hard backstop, per-query profiling and Fleet UI metrics for real-world cost, and agent-side buffering/backpressure so endpoints retry until server ack. Test infrastructure uses simulated agents (tens to hundreds of thousands per VM) to exercise agent check-ins and MySQL/Redis failure modes, plus an automated fleet control debug archive command to collect traces; these practices reduce incidents and shorten debugging cycles.
