One Instance · Subject to Availability
Free Database Health Audit
A free database audit from JusDB is a non-destructive, single-instance diagnostic review conducted under mutual NDA using least-privilege, read-only access. Within one week of access handover, Senior Database SREs deliver a prioritized health, performance, security, and replication assessment identifying critical bottlenecks, misconfigurations, and actionable remediation steps without touching production data.
The free audit covers one database instance. After a mutual NDA, our DBAs perform a least-privilege, read-only review and deliver a prioritized report within one week after the agreed access is ready. Implementation is not included, and the offer is subject to availability.
Request Free Database Health Audit
No production write access. Mutual NDA signed before any credentials are shared.
What's Included in Your Free Audit
Our DBAs perform a structured review across six critical areas to give you a practical picture of your database health.
Performance Analysis
Slow query identification, indexing gaps, query pattern analysis, and execution plan review.
Security Assessment
User privileges, authentication configuration, encryption status, and configuration-level risks.
Scaling Readiness
Replication health, connection pooling efficiency, capacity planning, and growth projections.
Configuration Review
Memory allocation, buffer pool tuning, cache hit ratios, and parameter optimization.
Cost Optimization
Resource utilization analysis, right-sizing recommendations, and cloud spend reduction opportunities.
Actionable Report
Prioritized findings with supporting evidence, severity, likely cause, and clear recommendations.
Critical Database Failure Modes Our Audit Uncovers
Standard dashboard monitoring often reads normal while catastrophic failure states develop silently underneath. Our free audit inspects these high-risk areas:
PostgreSQL Transaction ID (XID) Horizon & Autovacuum Stalls
Autovacuum fails to keep pace on high-write tables, advancing transaction IDs toward autovacuum_freeze_max_age. If unmonitored, PostgreSQL forcibly enters emergency read-only mode to prevent multixact corruption.
Audit calculates exact freeze horizon proximity, configures table-level vacuum cost parameters, and schedules proactive non-blocking vacuum freeze maintenance.
MySQL InnoDB Buffer Pool Choke & Redo Log Saturation
Heavy write spikes overwhelm the InnoDB log buffer, causing dirty page ratios to exceed innodb_max_dirty_pages_pct. This forces synchronous flushing checkpoints that freeze application query execution.
Audit profiles checkpoint age distribution, validates redo log capacity, and tunes innodb_io_capacity_max to match physical NVMe storage throughput.
Connection Starvation & Client Thread Exhaustion
Direct client connections from autoscaling microservices exhaust max_connections, allocating megabytes per thread and triggering severe kernel context switching and memory starvation.
Audit identifies client connection spikes and models optimal transaction-mode connection poolers (PgBouncer/ProxySQL) capped at 2x vCPU core count.
Our audit runs non-intrusive, read-only telemetry queries with strict statement timeouts to inspect bloat, dead tuples, and buffer pool stalls without taking catalog locks:
SELECT schemaname,
relname AS tablename,
n_live_tup,
n_dead_tup,
round(n_dead_tup::numeric / nullif(n_dead_tup + n_live_tup, 0) * 100, 2) AS dead_ratio,
last_vacuum,
last_autovacuum
FROM pg_stat_user_tables
WHERE n_dead_tup > 1000
ORDER BY dead_ratio DESC LIMIT 10;SELECT variable_name,
variable_value,
CASE variable_name
WHEN 'Innodb_buffer_pool_pages_dirty' THEN 'Dirty pages awaiting checkpoint'
WHEN 'Innodb_buffer_pool_wait_free' THEN 'Worker threads starved for free pages'
WHEN 'Innodb_buffer_pool_read_requests' THEN 'Logical cache read requests'
END AS diagnostic_meaning
FROM performance_schema.global_status
WHERE variable_name IN (
'Innodb_buffer_pool_pages_dirty',
'Innodb_buffer_pool_wait_free',
'Innodb_buffer_pool_read_requests'
);How Does the Free Audit Work?
Four simple steps from request to report — NDA signed before any access is shared.
Qualification & Scope
Start with a no-cost 30-minute call to confirm eligibility, the single instance in scope, required diagnostics, and availability. This call is a qualification step, not the technical audit.
Sign NDA
We sign a mutual NDA to protect your data before any credentials are shared. Your security comes first.
Share Read-Only Access
Provide customer-approved, least-privilege read-only access to the database and agreed diagnostic surfaces. No production write access is needed.

OpenSearch ServiceHow JusDB Free DB Audit compares to alternative tools.
Free automated tools often deliver noisy surface metrics without actionable query fixes. Here is how our manual, read-only SRE audit compares:
| Evaluation Vector | JusDB Free Audit | Cloud Advisors (AWS/GCP) | Automated SaaS Scanners | In-House Guesswork |
|---|---|---|---|---|
| Diagnostic Depth & Kernel Telemetry | Deep catalog queries, autovacuum starvation horizon, locks, dirty page ratios, WAL archiving, and redo log checkpoint profiling. | Surface-level CPU, RAM, and IOPS charts; zero visibility into query plans, internal catalog bloat, or lock wait trees. | Static linting of parameter settings; misses active dynamic locking, lock contention, or real-time query stalls. | Ad-hoc manual sampling; high risk of overlooking silent catalog degradation until an unexpected outage occurs. |
| Safety & Non-Destructive Access Model | 100% read-only, ephemeral bastion session with strict execution statement timeouts and zero production write access. | Read-only metrics from hypervisor layer, but recommendations lack application workload and query plan context. | Requires persistent credentials stored in third-party SaaS cloud databases, introducing credential exposure risks. | High operational risk of accidentally triggering table lock escalations while testing heavy diagnostic queries in production. |
| Query Execution Plan & Index Bloat Analysis | Line-by-line EXPLAIN ANALYZE reviews, identification of unindexed foreign keys, unused indexes, and index write amplification. | Generic slow query lists without actionable rewrite recommendations or schema index recommendations. | Automated heuristic flags generating high false-positive alerts without verifying physical access paths. | Guessing which indexes to add, frequently creating redundant composite indexes that degrade write throughput. |
| Disaster Recovery & Replication Lag Auditing | Deep audit of WAL/binlog replay latency, replica sync state, point-in-time recovery (PITR) validity, and backup restore runbooks. | Binary check of whether automated backup snapshot checkbox is enabled; zero validation of restore integrity. | Completely blind to cross-region replication health, replication slot bloat, and backup restore viability. | Untested backup cron jobs assuming pg_dump/mysqldump succeeds without verifying actual database restore viability. |
| Actionable Remediation Runbooks vs Fluff | Prioritized engineering report authored by Senior DBREs with exact SQL commands, config values, and non-blocking change scripts. | Vague automated suggestion cards with no rollback plans or engine-specific configuration context. | Automated compliance score percentage with voluminous boilerplate findings that burden engineering teams. | Disorganized internal notes and conflicting team opinions rarely consolidated into a clear engineering action plan. |
| Commercial Transparency & NDA Protection | 100% free for 1 production instance under a binding mutual NDA; zero purchase obligation, zero credit card requirement. | Free basic dashboard, but advanced enterprise database insights locked behind costly cloud support tiers (3–10% spend tax). | 14-day trial requiring credit card entry with automatic conversion into expensive recurring monthly subscriptions. | Consumes hundreds of expensive internal developer hours pulling engineers away from core product roadmap features. |
