インスタンスの稼働状態と診断

Interpret CPU, memory, disk, process and SRT error signals, test capacity, and preserve evidence before clearing incident logs.

Callaba での場所Dashboard header → Instance health
このモジュールの役割

Health signals explain whether the host can sustain the media workflow. Use them with module statistics: a healthy host does not prove a source is live, and a live source does not prove the host has headroom.

開始前の準備

  • A known normal baseline for this instance and workload.

  • Permission to inspect or clear operational error logs.

  • An external incident record before destructive cleanup.

設定の説明

運用者に必要なコントロールだけを説明し、内部フィールド名や実装イベントは表示しません。

Capacity

Read current host headroom.

CPU usage

Current processing load across media and application work.

Memory usage

Current RAM pressure.

Disk usage

Space available for logs, uploads, temporary transcoding and recordings.

Network speed test

Measured network capacity from the instance.

Run outside critical production peaks.

Operational evidence

Identify failures before changing configuration.

Process errors

Application/media process failures requiring module-level investigation.

SRT errors

SRT transport events and errors associated with contribution workflows.

Version notification

Installed application version and update context.

Clear error logs

Remove accumulated error entries.

Export or record incident evidence first.
IP location

Resolve regional context for a connection address when supported.

安全な初回ワークフロー

  1. 01

    Compare CPU, memory and disk with the known healthy baseline.

  2. 02

    Open process or SRT errors and identify the owning module and time window.

  3. 03

    Inspect that module's live statistics and real input/output.

  4. 04

    Run a speed test only when it will not distort production traffic.

  5. 05

    Record or export incident evidence before clearing logs.

Diagnose unstable live transcoding

Output frames drop after a new transcoding job starts.

アニメーション付きワークフロー図: Diagnose unstable live transcoding

構築手順

  1. 1

    Confirm the source bitrate is stable.

  2. 2

    Compare host CPU/memory before and after the job starts.

  3. 3

    Inspect output bitrate and frame rate.

  4. 4

    Remove unnecessary resize/frame-rate/codec work or move to measured host capacity.

使用する状況

Preserve evidence before clearing errors

Old errors obscure an active incident investigation.

アニメーション付きワークフロー図: Preserve evidence before clearing errors

構築手順

  1. 1

    Record the relevant error, timestamp, module and current release version.

  2. 2

    Save the associated module configuration and live statistics.

  3. 3

    Clear errors only after the evidence is externalized.

  4. 4

    Reproduce one controlled test and investigate only the new entries.

結果を確認

  • Capacity values match the expected workload and leave planned headroom.
  • Every active error can be tied to a time and owning module.
  • Clearing logs occurs only after evidence is stored elsewhere.

トラブルシューティング

Host health is normal but playback fails

確認項目
  • Inspect the source and output modules.
  • Check access, protocol and real client playback.
次に行うこと

Treat host health as one layer; repair the first failed media boundary.
