Now, let's dive into the data types you should monitor in real-time and explore how you can track them effectively.

Types of Data Suitable for Real-Time Monitoring

Different types of metrics provide different insights, allowing teams to make informed, real-time decisions that keep systems running efficiently and securely. 

Let’s break down the key data types that you will benefit from the most with real-time monitoring.

1. System Metrics: CPU Usage, Memory Utilization, Disk I/O, Network Traffic

System metrics give you insight into the health of your infrastructure. For example, a sudden spike in CPU usage might signal that a server is under heavy load, leading to slower performance. 

Monitoring network traffic can help you spot potential bottlenecks or security threats. By keeping a close eye on these metrics, teams can proactively manage resources and prevent downtime.

1. Pipeline Metrics: Data Volume, Streaming Latency, Error Rate

For organizations managing data pipelines, metrics like streaming latency and error rate are critical. If data volume suddenly increases and latency rises, your pipeline may struggle to keep up, potentially affecting real-time data processing. Real-time monitoring helps you catch these issues early, allowing teams to make adjustments before service interruptions occur.

1. Data Quality Metrics: Accuracy, Completeness, Timeliness, Validity, Consistency, Uniqueness

Monitoring the accuracy and completeness of your data ensures you’re working with reliable information. If data is missing or inconsistent, it can lead to flawed analyses and poor decision-making. Real-time monitoring of these metrics allows teams to spot and fix data quality issues before they impact operations, ensuring clean and actionable data.

1. Schema Evolution: Table Names, Data Fields, Data Types, Relationships

As data evolves, so do the schemas that structure it. Monitoring changes in table names, field types, or data relationships in real time ensures compatibility and reduces the risk of breaking downstream systems. When schema changes are detected immediately, teams can adapt without delays or errors in processing.

1. Data Lineage: Source and Collection Process, Data Transformations, Destinations

Understanding data lineage is essential for tracking where your data comes from, how it’s transformed, and where it’s going. Real-time monitoring of data lineage helps you ensure that every transformation and movement is tracked and that your data is trustworthy.
