The next step to effective IIS web server monitoring is to set up alerts and thresholds that notify you when your web servers deviate from the expected or desired levels of performance and availability. For instance, you can use ping tests, synthetic transactions, or health checks to verify that your web servers are reachable and functional, and set up alerts when they fail to respond or return an error code. Additionally, you can use web analytics, application performance monitoring, or load testing tools to measure and benchmark the response time of your web servers, and set up thresholds to warn you when they exceed a certain response time limit or show a significant increase in latency. Furthermore, you can use performance counters, IIS logs, or web analytics to track and compare the throughput of your web servers, and set up thresholds to alert you when they experience a sudden drop or spike in traffic or reach a certain load limit. Moreover, you can use event logs, IIS logs, or error tracking tools to capture and classify the errors that occur on your web servers and set up alerts to inform you when they generate a high number or frequency of errors or encounter a critical or unusual error. Lastly, you can use performance counters, resource monitoring tools, or capacity planning tools to monitor and optimize the resource utilization of your web servers, and set up thresholds to notify you when they consume a high percentage or amount of resources or run out of resources. Alerts and thresholds can help you detect and resolve issues before they affect your end users or cause downtime.
