    Warum überwachen? PostgreSQL?

    PostgreSQL ist die weltweit fortschrittlichste Open-Source-Relationaldatenbank, auf die man sich bei kritischen Workloads – von Finanzsystemen bis hin zu Geodatenanwendungen – verlassen kann. Die Überwachung von PostgreSQL ist unerlässlich, um lang laufende Abfragen zu erkennen, eine Überlastung der Verbindungen zu verhindern, den Zustand der Replikation zu verfolgen und Vacuum-Vorgänge zu optimieren. Die PostgreSQL-Integration von Xitoring bietet umfassende Datenbank-Observability.

    Was wir Monitor

    Active Connections

    Number of currently active connections to the PostgreSQL server.

    Transactions per Second

    Rate of committed and rolled-back transactions.

    Tuple Operations

    Rate of inserted, updated, deleted, and fetched tuples across all databases.

    Dead Tuples

    Number of dead tuples waiting for vacuum, indicating potential table bloat.

    Cache Hit Ratio

    Percentage of data requests served from shared buffers without disk access.

    Replication Lag

    Bytes or seconds behind the primary in streaming replication.

    WAL Generation Rate

    Rate of Write-Ahead Log data being generated.

    Lock Waits

    Number of queries waiting to acquire locks on database objects.

    Temp Files Created

    Number and size of temporary files created for query processing.

    Database Size

    Total disk space used by each database including indexes.

    Idle in Transaction

    Connections that are idle inside an open transaction, potentially holding locks.

    Checkpoints

    Frequency and duration of checkpoint operations.

    Auslöser & Benachrichtigungen

    Konfigurierbar Alarmauslöser

    Richten Sie benutzerdefinierte Trigger in Ihrem Dashboard ein, um benachrichtigt zu werden, sobald die Kennzahlen von „PostgreSQL“ Ihre festgelegten Schwellenwerte überschreiten.

    PostgreSQL Dashboard zur Konfiguration von Überwachungsauslösern

    Active Connections

    entscheidend

    Fires when active connections approach max_connections, risking new connection refusal and application errors.

    Replication Lag

    entscheidend

    Triggers when streaming replication falls behind, risking data inconsistency between primary and replicas.

    Dead Tuples

    Warnung

    Alerts when dead tuple count grows beyond threshold, indicating vacuum is falling behind and table bloat is increasing.

    Cache Hit Ratio

    Warnung

    Fires when cache hit ratio drops below threshold, indicating excessive disk I/O and potential memory pressure.

    Lock Waits

    Warnung

    Triggers when queries are blocked waiting for locks, indicating contention that degrades performance.

    Transaction Rate Drop

    entscheidend

    Alerts when transaction throughput drops significantly, indicating a potential database hang or performance issue.

    Importance of PostgreSQL Monitoring

    PostgreSQL handles mission-critical data for enterprises worldwide. Without proper monitoring, table bloat, replication drift, and connection exhaustion can lead to data corruption, outages, and unrecoverable failures.

    • Detect long-running queries and lock contention early
    • Prevent table bloat with vacuum performance tracking
    • Monitor streaming replication for data consistency
    • Identify connection leaks before pool exhaustion
    • Track WAL generation for storage capacity planning

    Erste Schritte in Protokoll

    1

    Install Xitogent on your server

    If you haven't already, install the lightweight Xitogent monitoring agent on your server.

    curl -s https://xitoring.com/install.sh | sudo bash -s -- --key=YOUR_API_KEY
    2

    Create a monitoring user in PostgreSQL

    Create a dedicated read-only user for Xitogent to collect metrics:

    CREATE USER xitoring WITH PASSWORD 'your_secure_password'; GRANT pg_monitor TO xitoring;
    3

    Enable the PostgreSQL integration

    Use the Xitoring dashboard or CLI to enable the PostgreSQL integration with the monitoring credentials.

    sudo xitogent integrate
    4

    Configure alert thresholds (optional)

    Set custom thresholds for metrics like replication lag, dead tuples, or connection count to get notified when something needs attention.
