The **Stats** tab gives platform owners a live, read-only snapshot of the server's hardware usage and background job health — hostname, CPU, memory, the campaign worker, and the campaign message queue. It auto-refreshes every 5 seconds. The Stats tab showing the four cards (Server Information, CPU, Memory, Campaign Worker) plus the Campaign Queue Status panel below ## What can I do here? This page is purely informational — there's nothing to configure — but you can monitor: * **Server Information**: hostname, platform, architecture, and uptime. * **CPU**: allocated cores (and physical host cores, if running in a container with different limits), processor model, current 1-minute load average with a utilization bar, and — if containerized — how many vCPUs are allocated versus the physical host. * **Memory**: total RAM (and physical host RAM if different, e.g. inside a container), used, free, and a usage bar that turns yellow above 60% and red above 80%. * **Campaign Worker**: whether the background job processor is Running or Stopped, how many workers are active, concurrency (jobs processed at once), and rate limit (messages/sec). If detection fails, an error/warning message is shown instead. * **Campaign Queue Status**: real-time counts of Active, Waiting, Scheduled (delayed), Completed, and Failed items in the campaign queue, plus an estimated processing time for anything currently waiting. ## How to use it 1. Open the **Stats** tab to see the four top cards: **Server Information**, **CPU**, **Memory**, and **Campaign Worker**. The Server Information and CPU cards side by side 2. Check the **CPU** and **Memory** utilization bars — a red bar (over 80%) signals the server is under heavy load and may need more resources. 3. Check the **Campaign Worker** card's status indicator — a green pulsing dot and "Running" means campaigns are being processed; a red dot and "Stopped" (or an error message) means campaigns won't send until the worker issue is resolved. The Campaign Worker card showing the Running status indicator, active workers, concurrency, and rate limit 4. Scroll to **Campaign Queue Status** to see how many messages are currently active, waiting, scheduled, completed, or failed. The Campaign Queue Status panel with its five count tiles 5. If there's a backlog, note the **Estimated processing time** shown for waiting items — it's calculated from the current rate limit and concurrency. 6. Leave the tab open to watch these numbers update automatically every 5 seconds — no manual refresh is needed.
