Database Metrics: Our Guide
Diving into the realm of databases, one cannot underscore the importance of robust and insightful metrics. These key indicators drive informed decision-making, enhance performance optimization, and propel strategic business growth. Our blog post today unwraps the must-know database metrics, serving as your compass in navigating the complex world of data management.
Query Response Time
The time it takes for a specific query to be executed and return results. This metric helps identify slow-running queries that could be optimized for better performance.
Transactions Per Second
This metric represents the number of transactions executed per second, indicating the overall workload and throughput of the database.
The time it takes to establish a connection to the database. A high connection time may indicate network issues or inefficient connection pooling.
The number of currently active connections to the database. This helps to monitor the database’s capacity to handle connections and potential bottlenecks.
The number of connections being reused, which helps to optimize resources and minimize connection overhead.
Cache Hit Ratio
The ratio of cache hits to total cache requests. A higher cache hit ratio indicates more efficient use of the cache, reducing the need for disk access.
The amount of disk space being utilized for storing data, logs, and configuration files. High disk usage can affect performance and backup operations.
Memory usage: Important to monitor as running out leads to swapping and reduced performance.
The percentage of CPU resources consumed by the database, which can help identify query optimization issues or hardware bottlenecks.
The degree to which the data within an index is fragmented, affecting query performance. High index fragmentation can be resolved by reorganizing or rebuilding the index.
Table Growth Rate
The rate at which the size of a table is increasing. Rapid table growth may indicate potential issues with database design or maintenance.
The number of times that multiple transactions are waiting on each other’s resources, causing a deadlock. Deadlocks can lead to performance slowdowns and should be minimized.
Row Lock Contention
The number of row-level locks being requested or held by transactions. High row lock contention can lead to performance degradation and blocked transactions.
Full Table Scans
The number of queries that require scanning an entire table, which can be less performant. Full table scans can often be reduced by implementing better indexing strategies.
The amount of time it takes for changes to be replicated from a primary database to its replicas. High replication lag can result in stale data being read from replica databases.

How we write these articles
We have not conducted any studies ourselves. Our article provides a summary of all the statistics and studies available at the time of writing. We are solely presenting a summary, not expressing our own opinion. We have collected all statistics within our internal database. In some cases, we use Artificial Intelligence for formulating the statistics. The articles are updated regularly. See our Editorial Guidelines.
