Key Metrics to Consider for Data Pipeline Observability

Below are the key metrics to ensure your data pipelines are running smoothly and delivering high-quality data:

  • Source Throughput Rates: This shows how much data your pipeline can handle in a specific time period. To ensure high throughput, clean data is essential. Check data quality as it enters the pipeline to avoid issues later.
  • Sensitive Data Detection Failure Rates: Analyze your data through profiling to find any sensitive information that could be a security risk. It’s important to mask this information from the beginning to prevent breaches as the data travels through the pipeline.
  • Error Rates: Keep track of errors and categorize them to understand how data flows. Decide which errors require immediate attention and which can be logged for later review. Have a plan for handling errors, such as restarting the process or rolling back to a previous point, to keep data flowing smoothly.
  • Execution Time: Monitor how long each stage of your pipeline takes to complete. This can help identify potential bottlenecks or areas prone to failure. Tracking execution times over time allows you to spot trends and proactively address issues.
  • Data Distribution: Data skew refers to data that deviates from the normal pattern and can indicate outliers or trends. Early detection of skew helps identify potential data drift.
  • Data Drift: Data drift refers to unexpected changes in the way your data is structured or what it means. There are two main types to monitor:
    1. Schema Drift: This happens when the structure of your data changes, like adding new fields or modifying existing ones. New systems can introduce schema drift, which might require adjustments to your pipeline.
    2. Semantic Drift: This occurs when the meaning of your data changes. Tools that manage metadata can help identify these changes by understanding the relationships between different data points.
Source Throughput Rates Explains how much data can be processed within a given time period.
Sensitive Data Detection Failures Accounts for failure to identify sensitive information. Profiling data at the point of ingestion can remediate this issue.
Error Rates Monitoring errors helps you understand how data moves and identify any problems that might stop it.
Execution Time Tracking how long each step takes can reveal bottlenecks or areas prone to errors.
Data Distribution This shows outliers (unexpected data points) and trends (changes in the data over time) in the distribution of data. These can signal potential issues with your data.
Frequency of schema drift This tracks how often the format of your data changes, like field or data type changes or modifying existing ones.
Frequency of semantic drift This identifies when the meaning behind your data changes, separate from structural changes.
