While reading a GitHub issue on the OpenTelemetry Collector about trying to send two versions of a metric, one with higher and one with lower cardinality, it occurred to me that we’ve never written on this blog about what is high-cardinality data exactly and how it matters to your OpenTelemetry observability. High-cardinality data refers to a dataset or data attribute that contains a large number of distinct values relative to the total number of data points.

OpenTelemetry can be used to trace Go applications that use Kafka to find performance issues and bugs. OpenTelemetry is an open-source project under the Cloud Native Computing Foundation (CNCF) that aims to standardize the generation and collection of telemetry data. Telemetry data includes logs, metrics, and traces. Apache Kafka introduced the ability to add headers to Kafka messages from version 0.11 onwards.

Monitoring Redis for performance issues is critical. Redis is famous for its low-latency response while serving a large number of queries. There are certain key metrics that you can monitor to keep track of your Redis instance performance. In this guide, we will go through key Redis metrics that should be monitored and ways to collect these metrics with in-built Redis tools.

Database monitoring is a critical component in your application performance monitoring. Apart from application code issues, database issues are one of the most common reasons for a bad user experience. MySQL is one of the most popular open-source DBMS that businesses have widely adopted. MySQL monitoring tools can help you identify potential issues with your database, keep a continuous check on your database instances, improve performance and detect and alert you about real-time issues.
