Aiven for PostgreSQL Monitoring

Why Aiven PostgreSQL Needs Deeper Monitoring

Aiven's management console shows CPU utilization, disk usage, connection counts, and replication status. These infrastructure metrics tell you when something is wrong but not why. When your Aiven PostgreSQL starts slowing down, you need query-level visibility to find the root cause.

MonPG connects to your Aiven PostgreSQL instance using the service URI from the Aiven console. The collector runs in your own environment — a container, VM, or Kubernetes pod — and queries pg_stat_statements, pg_stat_activity, and other system views that Aiven exposes. No Aiven API credentials needed, just a standard PostgreSQL connection.

What MonPG Adds to Aiven Monitoring

• Query performance analysis: Track every query in your Aiven PostgreSQL — execution time, rows returned, block reads/hits, temp file usage. Identify the top queries by total time, mean time, or I/O impact. See historical trends to catch regressions before they affect users.
• Index advisor with what-if simulation: Aiven doesn't provide index recommendations. MonPG analyzes your query patterns and recommends specific indexes, using what-if simulation to estimate the performance improvement before you create anything.
• Vacuum monitoring and tuning: Aiven manages autovacuum, but its default settings may not be optimal for your workload. MonPG tracks dead tuple accumulation per table, autovacuum run history, and XID age. The vacuum advisor suggests per-table autovacuum_vacuum_scale_factor and threshold adjustments.
• Connection management: Aiven plans have specific connection limits. MonPG tracks active, idle, and idle-in-transaction connections by application, database, and user. Get alerted before you hit the limit.
• Lock analysis: Real-time lock tree visualization showing which queries are blocking others. Lock wait history to identify recurring contention patterns.
• Schema change tracking: Track column additions, index changes, and constraint modifications across your Aiven PostgreSQL schemas. Know what changed and when.

Aiven-Specific Configuration

Aiven PostgreSQL uses SSL connections by default and provides connection pooling through PgBouncer. MonPG supports both configurations:

• Direct connection: Use the service URI from Aiven Console → Service → Connection Information. MonPG supports Aiven's required SSL mode (sslmode=require).
• Connection pooling: If you use Aiven's built-in PgBouncer, configure MonPG to connect through both the direct port (for pg_stat_statements access) and the pooler port (for PgBouncer monitoring).
• Read replicas: Monitor read replica performance and replication lag. Aiven's standby replicas expose the same system views, so MonPG can track query performance on replicas independently.

# Connect to Aiven PostgreSQL

Multi-Cloud Aiven Monitoring

One of Aiven's strengths is multi-cloud deployment — run PostgreSQL on AWS, Azure, or GCP from the same platform. If you have Aiven clusters across multiple clouds, MonPG provides a unified monitoring dashboard. Combined with monitoring for AWS RDS, Azure PostgreSQL, and self-hosted instances, MonPG is your single pane of glass for all PostgreSQL infrastructure.

Aiven for PostgreSQL Plans and Monitoring Depth

All Aiven PostgreSQL plans — from Hobbyist to Premium — support pg_stat_statements and the system views MonPG uses. The depth of monitoring is identical across plans. The only variation is resource limits (connections, storage) which MonPG tracks against your plan's boundaries.

Aiven's Karapace schema registry, Kafka Connect, and other data platform services are outside MonPG's scope — MonPG focuses exclusively on deep PostgreSQL monitoring, which is what makes it more effective than general-purpose tools.

Operational Risk Checks for Aiven PostgreSQL

MonPG runs 50+ operational checks against your Aiven PostgreSQL instances. These cover configuration drift (work_mem, shared_buffers, effective_cache_size), security posture (SSL settings, user permissions), performance risk (missing indexes, table bloat, unused indexes), and operational state (replication status, backup lag, connection utilization).

Each check includes severity (info, warning, critical), a detailed explanation, and actionable remediation steps. Learn more about MonPG's approach to PostgreSQL monitoring.
