Next, let‘s look at how Application Manager can be set up for monitoring WebSphere environments.

Installing Application Manager on Linux

Application Manager provides enterprise-wide monitoring capabilities and is simple to install on Linux and Windows systems.

I will walk through the installation process on a Linux server:

Download Application Manager from the ManageEngine website as a binary installation file. They provide a free perpetual license for up to 5 servers which is great for smaller environments.
Run the binary to start the installation wizard:

./ManageEngine_ApplicationsManager_64bit.bin

Accept the EULA and choose the Free edition to get started.
Select the installation directory. Defaults to /opt/ManageEngine/ApplicationManager.
Application Manager is bundled with an embedded PostgreSQL database by default. You can choose Microsoft SQL Server if needed.
Provide administrator credentials and choose any customizations like HTTPS port.
The installation will complete in under 5 minutes.

Once installed, Application Manager can be accessed through a web browser using the administrator credentials. The web-based user interface provides access to all monitoring capabilities.

Now let‘s look at adding the WebSphere servers you want to monitor.

Adding WebSphere Server for Monitoring

Login to the Application Manager web interface with admin credentials after installation.
Go to the ‘New Monitor‘ tab and click ‘Add New Monitor‘

App-Manager-Add-Monitor

Select ‘WebSphere Application Server‘ from the list.
Fill in the following details on the form:

Host name
Port
User name
Password
Properties to monitor

Click ‘Add Monitor‘ to complete adding the WebSphere instance.

Alternatively, you can choose to add a WebSphere cluster or cell for centralized monitoring.

Once added, Application Manager will automatically start collecting key metrics from the WebSphere server. The monitoring capabilities can also be customized as needed by choosing specific attributes or JMX counters to track.

Now let‘s explore how AppManager helps keep track of WebSphere performance and issues.

Monitoring Key IBM WebSphere Performance Metrics

Application Manager provides a very flexible and customizable monitoring environment for WebSphere through its dashboards.

Some of the key metrics that can be tracked out of the box include:

Category	Metrics
Availability	Server status JVM status App and module availability
Performance	Response time Load Throughput Garbage collection
Traffic	Sessions Active requests Connection pools
Errors	Failed transactions Exceptions thrown Connection leaks Slow transactions
Resource Usage	Heap/Non-heap usage Thread count CPU/Memory utilization

These metrics provide a holistic view of the factors affecting WebSphere performance – from load and traffic patterns to application errors to infrastructure health.

The dashboards offer flexibility to customize the metrics displayed in graphical and tabular formats:

The key here is allowing WebSphere admins to focus on the exact metrics they care about through personalized dashboards.

Application Manager also provides specialized dashboards for database servers, host resources and other backend systems. This allows correlating application performance with infrastructure health.

Now let‘s look at how to analyze historical trends using reports.

Using Historical Performance Reports

While dashboards provide real-time visibility, Application Manager has powerful reporting capabilities to help analyze historical data.

The pre-configured reports for WebSphere allow studying trends and patterns in performance. Some examples include:

Hourly JVM Reports – Analyze long-term memory usage patterns
Transaction Analysis Reports – View response times for business transactions across time periods
Error Trend Reports – Identify spike patterns for failed transactions
Performance Graphs – Compare throughput/response times before and after deployments
Heap Usage Graphs – Study garbage collection trends

These reports allow slicing and dicing historical data along different dimensions – by time period, server, application, transaction etc.

The reports can be exported as PDFs or Excel for sharing with teams. Scheduling options allow automating report generation and emailing them to stakeholders.

For example, a daily or weekly report sent to developers can highlight application issues like slow transactions that need debugging.

Overall, the pre-configured reports provide a starting point and Application Manager allows configuring custom reports tailored to any specific requirements.

Now let‘s discuss how to get notified of WebSphere application issues in real-time.

Configuring Alerts and Notifications

While monitoring dashboards and reports provide insights into past and current performance, being proactively notified of issues is also crucial.

Application Manager has robust alerting capabilities to notify administrators and developers when specific warning thresholds are crossed.

Some example scenarios where alerts are useful:

High application error rate – Alert if transaction failure rate exceeds 5%
Critical transaction slowdown – Be notified if checkout transaction exceeds 2 seconds
Server health degradation – Get alert for high CPU or memory
Application availability – Notify if a business-critical app goes down

These types of threshold-based alerts can be configured through the Application Manager interface:

Alerts can then be delivered through:

Email
SMS
Slack/MS Teams notifications
Native mobile apps
Ticketing system integration

Quick notifications can help administrators take corrective actions faster – such as restarting a slow application during peak traffic periods to provide a smoother user experience.

Now let‘s look at how Application Manager integrates with ManageEngine‘s APM Insight tool to provide code-level visibility.

Enhancing Monitoring with APM Insight

While Application Manager provides infrastructure and application-level monitoring capabilities, many WebSphere customers also need code-level visibility.

This helps developers debug issues right down to the method and line of code causing slowness or errors in transactions.

Application Manager can integrate with ManageEngine APM Insight to provide this code-level view.

APM Insight is an application performance monitoring tool that instruments application code using agents and analyzes individual transactions.

Some ways AppManager integrates with APM Insight to complement monitoring:

End-to-end transaction tracing – Trace user transactions across WebSphere and other application tiers
Waterfall transaction analysis – Isolate slow code segments within transactions
Errors and exceptions – View code errors and stack traces for faster debugging
User session analysis – Track user actions before reported issues

This integration helps WebSphere administrators collaborate with development teams for faster troubleshooting.

For example, slow SQL queries identified by AppManager can be shared with developers to analyze the ORM code responsible using APM Insight‘s method-level tracing.

Sample WebSphere Monitoring Setup

Now that we have walked through its capabilities, let‘s look at an example monitoring setup using Application Manager for a sample WebSphere environment.

WebSphere Environment
