    Why monitor PostgreSQL?

    PostgreSQL is the world's most advanced open-source relational database, trusted for critical workloads from financial systems to geospatial applications. Monitoring PostgreSQL is essential to detect long-running queries, prevent connection saturation, track replication health, and optimize vacuum operations. Xitoring's PostgreSQL integration delivers comprehensive database observability.

    Metrics

    What we 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.

    Triggers & Alerts

    Configurable alert triggers

    Set up custom triggers in your dashboard to get notified the moment PostgreSQL metrics cross your defined thresholds.

    Active Connections

    critical

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

    Replication Lag

    critical

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

    Dead Tuples

    warning

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

    Cache Hit Ratio

    warning

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

    Lock Waits

    warning

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

    Transaction Rate Drop

    critical

    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
