PostgreSQL Monitoring Without Any Changes
True zero-instrumentation PostgreSQL monitoring. Our eBPF technology captures every query at the kernel level by analyzing the PostgreSQL wire protocol. No extensions, no configuration, no database changes required.
How We Monitor PostgreSQL
Using eBPF to intercept network packets and decode the PostgreSQL wire protocol
Wire Protocol Analysis
Capture every PostgreSQL query using eBPF kernel-level network interception - no pg_stat_statements needed
Full Query Visibility
Parse Simple Query, Extended Query protocol with PARSE/BIND/EXECUTE, and extract row counts automatically
Zero Configuration
Automatic protocol detection on port 5432 - no database configuration, extensions, or restarts required
Performance Metrics
Track query latency, rows returned, error rates, and transaction patterns from wire protocol data
Distributed Tracing
Correlate database queries with application requests for full distributed trace visibility
Prepared Statement Support
Full support for prepared statements including parameter binding and execution tracking
PostgreSQL Protocol Analysis
eBPF Network Interception
Our eBPF programs attach to kernel network functions to capture all PostgreSQL traffic on port 5432. This happens at the kernel level before the data reaches PostgreSQL, giving us complete visibility without any database overhead.
// eBPF captures PostgreSQL packets
SEC("kprobe/tcp_sendmsg")
int trace_postgresql_queries(struct pt_regs *ctx) {
// Extract PostgreSQL wire protocol data
// Parse query messages (type 'Q')
// Track prepared statements (P/B/E)
}Wire Protocol Parsing
We parse the PostgreSQL wire protocol to extract:
- Simple queries (SELECT, INSERT, UPDATE, DELETE)
- Extended query protocol with prepared statements
- Row counts from CommandComplete messages
- Error messages with SQLSTATE codes
- Transaction boundaries (BEGIN/COMMIT/ROLLBACK)
What We Capture
True Zero-Instrumentation PostgreSQL Monitoring
No extensions, no configuration, no code changes. Just deploy and see everything.
