Added

  • Per-container CPU and memory stats - ContainerInfo now includes individual resource usage for each container

  • Prometheus metric watcher_invalid_services_total - tracks count of services that failed config validation

  • Container ID field added to ContainerInfo struct for resource stats lookup

Fixed

  • CRITICAL: Web UI template error - added missing Now field to uiData struct (template rendering was completely broken)

  • CPU/memory stats now displayed per-container instead of aggregated at service level

  • Monitor now stores per-container resource usage keyed by container ID

Changed

  • Resource stats collection enhanced to track individual container metrics

  • API enriches container list with CPU/memory stats from monitor

  • Container details in web UI now show accurate per-container resource usage

    Technical Details

    Per-Container Stats Implementation

    The monitor now maintains two maps:

  • latest map[string]ServiceStats - Service-level aggregated stats (unchanged)

  • containerStats map[string]ContainerStats - Per-container stats keyed by container ID API flow:

    1. Monitor collects stats for each container and stores by ID
    2. Updater lists containers and includes container ID in ContainerInfo
    3. API enriches containers with stats during snapshot creation
    4. Web UI displays CPU/memory per container in expandable details

    Invalid Services Metric

    New Prometheus metric exposed via /metrics:

    # HELP watcher_invalid_services_total Number of services that failed config validation
# TYPE watcher_invalid_services_total gauge
watcher_invalid_services_total 1

    Enables alerting on misconfigured services that were skipped during startup.
