The value of web server monitoring
Web servers are the front door to your applications. When IIS slows down or stops responding, users notice immediately. Consider the following:
- A spike in HTTP 500 errors might indicate a failed deployment, a database connection problem, or an exhausted application pool. Without monitoring, you rely on user complaints to discover problems.
- Worker process recycling can silently degrade performance. If application pools restart too frequently, in-flight requests are dropped and session state is lost.
- Connection queue saturation means your server is rejecting legitimate traffic. Capacity planning requires historical data that only monitoring can provide.
Every minute of web server downtime has a direct impact. If you run customer-facing applications, outages translate to lost revenue and eroded trust.
Why monitor IIS with Grafana Cloud?
Grafana Cloud’s IIS integration provides an out-of-the-box monitoring solution designed for IIS web servers. After you deploy the integration, it immediately starts collecting the most relevant metrics from your IIS instances.
The integration collects metrics including:
- Request throughput — requests per second across all sites
- Error rates — HTTP 4xx and 5xx response codes
- Active connections — current client connections and connection attempts
- Worker processes — CPU and memory usage per application pool
- Bandwidth — bytes sent and received per site
The collected data populates pre-built dashboards and alerts that represent industry best practices for IIS monitoring.
