JENNIFER for Enterprise Application Performance Management
Application Performance Management, or APM, refers to the discipline within systems management that focuses on monitoring and managing the performance and service availability of software applications. Application performance relates to how fast transactions are completed on behalf of, or information is delivered to, the end user by the application via a particular network, application and/or web services infrastructure. Unlike traditional system management (SMS, NMS), APM enhances the organization’s ability to manage the enterprise application services and resolve application performance problems, resulting in reduced Total Cost of Operation (TCO) and enhanced customer service.
JENNIFER Service Positioning – Specialist in Production System Management
From the early development phase to the production phase in a live environment, there are many times in the course of an application’s lifecycle when an APM solution can provide much help in managing its performance and quality. Most APM solutions that are available today are designed to be used during the development phase or the early part of the testing phase, helping developers and system administrators during the pre-production of enterprise applications. However, these solutions are not designed to be proficient in maintaining applications once they are deployed in a live system.

Even the most modern APM solutions that claim to have end-to-end capability are actually development tools with some basic production environment monitoring capability - thus they are not suitable for a task as important as managing and maintaining business-critical applications in a production environment … which has a direct effect on the business. In contrast, JENNIFER® has been specifically designed with production system monitoring in mind, making it the only solution to be “Specialist in Production System Management" available in the market.

JENNIFER® is the Application Performance Management (APM) solution developed by JenniferSoft Inc. JENNIFER® provides total application performance management and operational support services for enterprise web-systems, performing tasks such as real-time resource and service monitoring, immediate performance problem diagnosis and effective performance problem resolution.

JENNIFER Dynamic Monitoring
In Application Performance Management, the concept of enterprise performance monitoring can be classified into two key aspects: Service Monitoring and Resource Monitoring.

Service Monitoring
When monitoring the status of the application services, it is important to retrieve the performance data in real-time and grasp the mutual relationship between each service transaction. A delay in transaction response time may have originated from not just that transaction - but from a combination of all the transaction's resource bottlenecks. JENNIFER® provides the following features in service monitoring:
Concurrent User
Active Service
TPS, Arrival and Service Rate
Real-Time Transaction Response Time
Application Naming Dynamic Substitution
SQL Tracing (Including BIND Variable)
Transaction Profiling (Class/Method Level)
HTTP POST Request KEY/VALUE Tracking
Resource Monitoring
Resource monitoring includes managing the physical and logical resources used in running an application service. JENNIFER® provides the following features in resource monitoring.
JDBC Connection Pool Status
JVM Heap Memory Usage
FILE Read/Write Status
Collection/Live Object Count
Status of Java Application Server Resource Used by JMX
Performance Data Analysis
The performance problem in a web-system can be categorized into two types: a) conditional performance problems caused by anomalous circumstances … or
b) relative performance problems caused by an increase in load and throughput that is more than the amount the system can handle. JENNIFER® possesses various types of data collection and analysis modules for detecting all types of performance problems.
Memory Leak Detection
Java Collection/Live Object, Application Tracing
JDBC Connection/Statement/ResultSet Tracing
JDBC Transaction (commit/rollback) Tracing
Application Exception Tracing
SQL, SQL Exception Tracing
Dump on Running Service
HTTP Session Dump Capability
Reporting Loading Class Hierarchy Analysis
Loaded Class Bytecode Deassembling
Real-Time Active Service Monitoring
JENNIFER® illustrates active service runtime in different colors and displays it via the equalizer graph in real time.

JENNIFER® transmits the performance data through a reverse-direction protocol that connects from the JENNIFER Server to the JENNIFER Agent whenever a user requests the data. Using this method, JENNIFER® can extract the snapshot information of the running active services. Active service data shown in JENNIFER® is not a summarized data of events that occurred in the past but the real-time data concerning active services.

Response Time Scatter Graph (X-View)
JENNIFER’s response time scatter graph, called X-View, presents the response time of all service transactions as plots in a scatter graph. The vertical axis is the response time of an individual transaction and the horizontal axis is the end time of each transaction’s runtime.
Using the X-View, a user can not only detect the delay in response time for the specific transaction(s) but also the root-cause behind the delay in the response time. The plots may form different patterns in X-View (see above screenshots) that a user can use to identify or predict the type of performance problem being experienced. The X-View is a powerful and intuitive tool that is far more useful than using any amount of line graphs combined.
JENNIFER X-View / High Level Transaction Profiling
Within the X-View, select one or more plots using the drag & drop feature with the mouse to see the specific details about the selected transactions such as Method Call Path, SQL, File/Socket and others. When the plot(s) is selected, a separate pop-up screen with the individual transaction information (X-View) appears.
The X-View displays the detailed information in the following areas: 1) SQL queries, 2) External system and interface (including Legacy), 3) Accessed files and sockets, and 4) Tier and Layer high-level class/method profiling information.
Extended Thread View
The Extended Thread View shows the actual running foreground and background threads in a graphical form. A complete list of all running threads monitored by JENNIFER® is also available.

Selecting a thread in the Thread’s list shows additional details according to the state of this thread.

Business Groups
Using a dynamic & graphical overview of freely-definable business-groups, JENNIFER® can organize monitored applications into groups by tasks or by business area. When one or more business groups experience performance issues, the JENNIFER® user can go directly from the business-group monitoring screen to the problem analysis tool.

Dynamic Profiling
JENNIFER® can register additional package, class, method and/or activate/deactivate transaction profiling without restarting the web application server.
Alert Groups
A dynamic graphical summary view of alarms allows the direct selection of critical alarms in your environment. A mouse click opens the filtered list of alarms to get a first hand overview. The next click opens an associated tool to find the problem as fast as possible.

Dynamic StackTrace
The traditional method for extracting a Java full StackTrace is by intentionally causing an exception/error for an application resource and outputting it onto the stacktrace; JENNIFER® can register a class/method during operation, allowing a dynamic full stacktrace of additional class/method without changing the application source code.
Monitoring per Domain
In a large scale enterprise environment, many different business systems may exist, triggering a need for a solution that individually monitors each business system under one integrated view. JENNIFER® provides performance management capabilities per domain that allow the user to allocate multiple business systems into different domains and manage each system under one umbrella.
Extended Monitoring Adaptor
JENNIFER® extracts the performance data from the web application server and the communication between the Java Application Server and other system devices. JENNIFER® incorporates the Extended Monitoring Adaptors Functionality (EMAF) that allows performance data from other system devices to be extracted and to be input into JENNIFER® for analysis and reporting. Broadly speaking, JENNIFER® offers 3 types of Extended Monitoring Adaptor functionality.

REMON: JENNIFER® supports user-customizable extended adaptors written in shell script, java, c-library, Telnet, SSH, SQL, and others.
ExtraAgent: ExtraAgent is imbedded in the Java Application Server interface and communicates directly with REMON (Extended Monitoring Adaptor).
LogWatcher: LogWatcher extracts the data from various formats of user log files and provides real-time analysis, monitoring, and alert services.

Application / SQL Tuning
The response time of executed queries can be traced without affecting the system performance. The relative connection between SQL and the application that used it, and the proportion of response time spent on SQL over the total response time of the application can be viewed and analyzed via JENNIFER®.
Dynamic Class / Method Level Profiling
SQL Tracing (Including BIND Variable)
Method Parameter/Return Key Value Tracing
Backend Transaction Tracing (CTG, WebT, TC/Jolt)
TOP 10 Application and SQL
File/Socket Connection Tracing
Automatic Alert System
JENNIFER® has classified many different error types that can exist in applications which negatively affect the system performance. Error/Exception alerts are grouped into “Critical”, “Error”, and “Warning” and managed by date/time. The user can also add new error/exception types using the extension adaptor.
Statistical Analysis and Reporting
Statistical Analysis of Services
JENNIFER® can show the quantified statistical data such as visitor count, response time, resource usage, and other performance/business data concerning the service transactions.

User Customizable Reports
JENNIFER® can store the performance data into the DB and show the data in customizable reports. Templates for commonly used performance and business reports are readily available.

Report Scheduler
Report scheduler allows the user to generate periodic (daily/weekly/monthly) reports automatically.
JENNIFER Structure
Installed on each web application server, the JENNIFER Agent collects the performance data and transmits it to the JENNIFER Server.

The JENNIFER Server receives the performance data from the JENNIFER Agent and then processes/displays it in the JENNIFER Control dashboard for managing statistical data and alerting any problems and errors, etc.

Data processed by the JENNIFER Server is stored in a DB File system (the JENNIFER Repository) and JENNIFER retrieves any data necessary for system performance analysis from there.

The JENNIFER console uses java applets together with a web browser and does not require the installation of a specific client. Thus, a user can access the JENNIFER console from any internet enabled computer.
