MSSQL 監視
設定作業を一切行わずに、Microsoft SQL Server のクエリパフォーマンス、待機統計、バッファキャッシュ、およびトランザクションログの状態をリアルタイムで監視できます。
なぜ監視するのか MSSQL?
Microsoft SQL Serverは、世界中のエンタープライズアプリケーション、データウェアハウス、ビジネスインテリジェンスプラットフォームを支えています。クエリ実行プランの最適化、待機統計の追跡、バッファキャッシュの効率管理、デッドロックの検出を行うためには、MSSQLの監視が不可欠です。XitoringのMSSQL統合機能により、SQL Serverインスタンスの状況を包括的に把握することができます。
私たちが モニター
Batch Requests/sec
Number of SQL batch requests received per second.
Buffer Cache Hit Ratio
Percentage of page reads satisfied from buffer pool vs physical disk reads.
Page Life Expectancy
Average time (seconds) a page stays in the buffer pool — lower values indicate memory pressure.
Wait Statistics
Top wait types and durations indicating resource bottlenecks.
Deadlocks/sec
Number of lock requests that resulted in deadlocks.
Transaction Log Usage
Percentage of transaction log space used per database.
User Connections
Number of active user connections to the SQL Server instance.
Compilations/sec
Number of SQL compilations and recompilations per second.
Lock Waits/sec
Number of lock requests that required the caller to wait.
Index Fragmentation
Fragmentation level of indexes across databases.
CPU Usage
SQL Server process CPU utilization vs total system CPU.
Database Size
Data and log file sizes for each database.
設定可能 アラートのトリガー
ダッシュボードでカスタムトリガーを設定し、MSSQLのメトリクスが定義した閾値を超えた瞬間に通知を受け取れるようにします。
Buffer Cache Hit Ratio
重要なFires when cache hit ratio drops below threshold, indicating insufficient memory for workload.
Page Life Expectancy
警告Triggers when PLE drops below threshold, meaning pages are being flushed too quickly from memory.
Deadlocks
重要なAlerts when deadlock rate exceeds threshold, indicating lock contention in application queries.
Transaction Log Usage
重要なFires when transaction log usage exceeds threshold, risking write failures.
User Connections
警告Triggers when connection count approaches limits, risking connection refused errors.
Wait Statistics
警告Alerts when specific wait types spike, indicating resource bottlenecks (CPU, I/O, memory, locks).
Importance of MSSQL Monitoring
SQL Server runs mission-critical enterprise workloads — from ERP systems and financial databases to e-commerce platforms. Without monitoring, buffer pressure, deadlocks, and transaction log bloat can cause outages and data corruption.
- Detect memory pressure through buffer cache and PLE metrics
- Monitor wait statistics to identify the root cause of slowdowns
- Track deadlocks to fix application-level locking issues
- Ensure transaction log space for uninterrupted write operations
- Optimize index usage to maintain query performance over time
