アプリケーションパフォーマンスプロファイリング¶
パフォーマンスの問題は、一定時間内に操作を完了できなかったために発生するソフトウェア障害の一種です。たとえば、自律走行車や高頻度の金融取引プラットフォームなど、ミリ秒単位の分解能で 必要なアクションを実行できないリアルタイムシステムは、最終的に重大な社会経済的影響をもたらします。致命的なエラーやロジックエラーとは異なり、パフォーマンスの問題は システムクラッシュや不正確な出力のような明らかな失敗を引き起こさないかもしれません。
パフォーマンスの問題を診断するために、プロファイラーと呼ばれる計装機器を使用して、プログラムの実行状態を定期的にサンプリングします。プロファイルデータを分析することによって、 CPU /メモリリソースの過剰消費を問題のあるソースコードのファイルと機能に切り分けることができます。
PSYGIG Mobility IoT SDK は、全体的なパフォーマンスが影響を受ける可能性があるプログラムコード内のホットスポットを識別するための計測ツールを提供します。Application Performance Profiling APIには、組み込みシステムへの統合に適した多くの機能が含まれています:
アプリケーションに直接動作し、ソースコードを再コンパイルする必要はありません
サードパーティのAPMプラットフォーム とのシームレスな統合
CPU使用率プロファイリングデータを自動的に収集し、パフォーマンスホットスポットを識別するコールツリーを生成します
定期的なメモリ使用量のスナップショットを生成し、メモリの割り当て/割り当て解除場所のスタックトレースを提供します
プログラムのメモリリークを特定する
アプリケーションパフォーマンスHTMLレポートを生成する
psymon の使用¶
ソースコードを変更しなくても、 psymon スクリプトを使用してプログラムを実行することで、
アプリケーションに対するパフォーマンスプロファイリングを即座に有効にできます。例
psymon --profile "/path/to/your/app --arg1 --arg2 --arg3"
オプションリストは psymon-manページ を参考ください。
PSYGIGトリアージSDK APIの使用¶
Application Performance Profiling APIには、 単一のヘッダーファイル
を含めて libpsyiage 共有ライブラリをリンクすることによってアクセスできます。詳細については、
高度なセットアップ - libpsyiageを使用したアプリケーションの構築 を参照ください。
CPUプロファイラを起動/停止¶
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 | #include <psyiage/psyiagesdk.h>
int main(int argc, char **argv)
{
psyiage_handle pah; // handle to psyiage instance
/* ... Initialize code omitted for simplicity ... */
// Start CPU profiler
rc = psyiage_profile_enable_profiling(pah, 10);
/* Some code to profile */
// Stop CPU profiler
rc = psyiage_profile_enable_profiling(pah, 0);
/* ... Cleanup code omitted for simplicity ... */

メモリ使用量のスナップショットを生成¶
注釈
メモリ使用量のスナップショットの生成 は進行中です。この機能をベータテストすることに興味がある方は、 連絡 ください。

/* ... Initialize code omitted for simplicity ... */
// Capture memory snapshot
rc = psyiage_profile_memory_snapshot(pah);
/* ... Cleanup code omitted for simplicity ... */
