Key Metrics to Monitor

When it comes to monitoring web application performance, there are several key metrics that should be tracked. These metrics provide insight into the application’s overall health and can help identify potential issues before they become critical.

Response Time

Response time measures the time it takes for a web application to respond to a user’s request. This metric is critical because it directly impacts the user experience. Slow response times can lead to frustrated users and lost revenue. Response time should be monitored at both the application and individual transaction levels.

Throughput

Throughput measures the number of transactions or requests a web application can handle in a given period. This metric is important because it provides insight into the application’s capacity. If throughput is consistently low, it may be an indication that the application needs to be optimized or that additional resources are needed.

Error Rate

Error rate measures the percentage of requests that result in errors. This metric is important because it provides insight into the application’s stability. High error rates can indicate bugs, configuration issues, or other problems that must be addressed.

Resource Utilization

Resource utilization measures the CPU, memory, disk space, and other resources a web application uses. This metric is important because it provides insight into the efficiency of the application. If resource utilization is consistently high, it may indicate that the application needs to be optimized or that additional resources are needed.

Monitoring these key metrics can help ensure a web application performs optimally and delivers a great user experience. Tracking these metrics over time makes it possible to identify trends and make data-driven decisions about optimising the application.
