Monitoring Availability¶

Monitoring availability depends on the swarm host agent version, local Docker state, and the browser's ability to establish a monitor session with the swarm host.

What Is Available¶

Monitoring-enabled swarm hosts can provide:

• host resource charts
• deployment resource charts
• game health charts when a game metrics target is configured
• collector health summaries
• current alert state

Older swarm hosts continue to work for launches, logs, backups, and file management even when the local monitoring stack is not available.

During Agent Or Host Updates¶

It is normal for monitoring to be temporarily unavailable while an agent update, host restart, Docker restart, or monitoring stack repair is in progress. The UI should recover after the agent reconnects and the collectors complete their first scrape.

Monitoring failures should be treated as visibility problems, not as deployment lifecycle failures. Game containers remain managed through their normal task queue.

Before Relying On Monitoring¶

For a new swarm host, verify:

• the host appears online in Swarm Hosts
• monitoring diagnostics report healthy collectors
• host charts show recent samples
• deployment charts show samples for a running deployment
• game health charts appear only for deployments configured to export game metrics
