Backpressure and Admission Control
When a downstream service slows down, an agent that keeps enqueuing work turns a slowdown into an outage. Bound how much work is in flight, dedupe repeated triggers into a single window, give automatic fixes a cooldown and a daily run cap, and downgrade alerts instead of suppressing them so the signal survives the storm.
Commands
$ openclaw auto-fix add --name "Service Restart on OOM" --condition "service_oom_killed = true" --action "Rolling restart of the affected service" --approval "auto" --notify "#ops-alerts" --cooldown "30m"
$ openclaw auto-fix add --name "Queue Drain Assist" --condition "queue_depth > 1000" --action "Pause new scheduled work for 10 minutes and post the current depth" --approval "auto" --notify "#ops-info" --max-runs "3 per day"
$ openclaw alert-rule add --name "Queue Depth Shed" --group-by "host,metric" --window "15m" --action "While the same host and metric keep firing, send one alert and append the running count instead of a message per occurrence."
$ openclaw connect simulate Grafana --alert "Queue depth" --metric "queue_depth" --value "1200" --host "api-prod-01" --duration "8 minutes"

Slow down the intake before the queue does it for you
Backpressure and Admission Control# Slow down the intake before the queue does it for you When a downstream service gets slower, an agent that keeps enqueuing work at the same rate turns a slowdown into an outage. The service does not have to fail for this to happen. It only has to be slower than the rate at which new work arrives,
