## Query performance and health monitoring for MySQL and PostgreSQL

| Database       | Key metrics                                   | Alert examples                         |
|----------------|-----------------------------------------------|----------------------------------------|
| **MySQL**      | Queries/sec, connections, InnoDB, replication | Connection exhaustion, replication lag |
| **PostgreSQL** | Transactions, locks, vacuum, connections      | Lock contention, vacuum failures       |

## Questions answered

| With Database Observability, you can answer…              |
|-----------------------------------------------------------|
| Which queries are slowest in my PostgreSQL database?      |
| Is my MySQL replication falling behind?                   |
| How many connections does my database have vs. its limit? |
| When will my database run out of disk space?              |
| What’s causing lock contention in PostgreSQL?             |

## Problems solved

| Problem                                        | Solution                                  |
|------------------------------------------------|-------------------------------------------|
| Database issues discovered when users complain | Proactive alerts catch problems early.    |
| No visibility into query performance           | Performance dashboards show slow queries. |
| Replication failures surprise the team         | Lag monitoring with alerts                |
| Connection pool exhaustion crashes apps        | Connection monitoring prevents outages.   |

## What you get

| Component                 | Description                          |
|---------------------------|--------------------------------------|
| **Performance dashboard** | Query rates, latency, throughput     |
| **Connection monitoring** | Pool usage, active connections       |
| **Storage metrics**       | Disk usage, table sizes, growth      |
| **Replication health**    | Lag, sync status, failover readiness |

> **Other databases?** For MongoDB, Redis, Elasticsearch, and more, use Integrations for pre-built dashboards or data source connections to query them directly. Database Observability is also expanding — native support for more databases is coming.
