# Monitor .NET applications, fix performance bottlenecks, and deliver smooth user experiences

Get code-level insights, track errors, and optimize your .NET services with real-time monitoring.

- Monitor response times, throughput, and error rates
- Trace slow transactions down to individual methods
- Identify unhandled exceptions and failed requests
- Visualize key metrics with intuitive dashboards

Have you had to restart your app pool at 3AM just to keep the site running? Or spent hours scrolling through event logs, unsure if it's a memory leak or a locked thread?

Microsoft .NET applications are powerful, but complex. From IIS crashes to connection pool timeouts, diagnosing issues manually can be time-consuming and frustrating.

Applications Manager streamlines .NET application monitoring with correlated insights across the app, server, and cloud layers—so you can stop guessing and start resolving issues before users are affected.

## Dive deep into your .NET server health and prevent sluggish app performance

Your .NET application server forms the backbone of your app performance. By actively monitoring it, you can preempt performance degradations and ensure consistent service delivery.

### Memory Usage:

Track .NET memory consumption across heap and non-heap spaces. Identify memory leaks early and optimize garbage collection behavior to maintain healthy memory utilization.

### Thread Pools:

Gain visibility into active and waiting threads. Detect thread pool exhaustion and configure thresholds that prevent application slowdowns due to blocked or limited threads.

### Locks:

Visualize lock acquisition, wait times, and deadlock patterns in real time. This helps you resolve thread contention issues and long-running operations that impact user experience.

### Exceptions:

Monitor unhandled exceptions, runtime errors, and application-level faults. Identify recurring error types and affected modules for quick remediation.

### Connections:

Stay on top of connection activity and pool utilization. Detect connection spikes, drops, and exhaustion patterns before they escalate into downtime.

### Network Traffic:

Understand traffic volume, latency, and throughput across the .NET network layer. Pinpoint anomalies and optimize communication between distributed services.

### JIT Compilation:

Track JIT (Just-In-Time) compiler metrics to reduce code compilation delays and improve application startup performance.

## Monitor the performance of .NET and .NET Core applications

To isolate issues at the application layer, it is essential to get a granular view of your .NET application's execution flow, including method calls, database queries, external service interactions, and more. Applications Manager provides end-to-end monitoring for .NET and [.NET core applications](https://www.manageengine.com/products/applications_manager/dot-net-core-monitoring.html) in both development and production environments, including **code-level insights**, database performance, and infrastructure metrics.

- Instrument .NET applications for popular web frameworks such as ASPX and MVC.
- Monitor .NET performance alongside data from other components such as web service calls (ASMF, WCF, web API), database calls (Microsoft SQL Server, MySQL, Oracle, PostgreSQL, MongoDB, Cassandra), Queues (Microsoft Message Queue, and others (Open web interface for .NET).
- Map .NET applications and their supporting architecture in real-time with **automated service maps**.
- Use **distributed tracing** for enhanced debugging if your .NET application uses microservices and distributed architectures.

## Resolve user-impacting issues faster with context-driven diagnostics

Here’s how customers typically use Applications Manager to resolve performance issues:

- **Slow checkout?** Trace latency to a slow payment gateway call
- **Spiking error rates?** Identify exception patterns and pinpoint faulty releases
- **Outages?** Correlate with IIS pool crashes or Azure VM restarts

With context-rich diagnostics, you move from symptoms to root cause faster.

Applications Manager's comprehensive [.NET application monitoring](https://www.manageengine.com/products/applications_manager/dot-net-application-monitoring.html) capabilities help developers identify and address a wide range of issues, such as:

- Memory leaks and inefficient memory allocations
- Excessive CPU usage
- Slow queries and other database related performance issues
- Network latency, packet loss, and throughput
- Thread contention
- Deadlocks
- Slow endpoints
- Error rates and exceptions
- User experience issues, such as slow page load times
- Resource exhaustion issues
- Scalability issues

## Monitor IIS performance metrics before users notice issues

Applications Manager also supports [IIS monitoring](https://www.manageengine.com/products/applications_manager/iis-monitoring.html) that allows you to manage web apps hosted on IIS. Applications Manager enhances visibility beyond what IIS Manager or PerfMon can offer.

- Know when a site is down even before users report it
- Track CPU, memory, and queue length for each app pool
- Identify restarts, request spikes, and configuration issues

## Unify infrastructure and application monitoring for Azure-hosted .NET services

If your .NET applications are running in Azure, monitoring Azure itself is crucial for understanding your application's health, performance, and reliability. Applications Manager's [Azure monitoring](https://www.manageengine.com/products/applications_manager/azure-monitoring.html) capabilities enable you to:

- Ensure that the Azure resources your .NET application depends on (eg: Virtual machines, App Services, databases, storage accounts, etc.) are available and functioning correctly.
- Monitor key infrastructure metrics like CPU utilization, memory consumption, disk I/O, network latency, and request counts for your Azure resources.
- Detect if slowdowns are caused by VM-level CPU throttling or app layer issues.
- Correlate Azure resource usage with cost insights.

For example, a spike in latency matches with auto-scaling events. Now you can tune your scale rules instead of over-provisioning.

## Monitor your entire Microsoft ecosystem from a single console

Applications Manager can also help keep tabs on your broader Microsoft ecosystem with support for monitoring Windows servers, SQL server, Exchange, Hyper-V, SharePoint, MSMQ, BizTalk, Microsoft 365, etc.
