Release Note 4.1.6.56

New and Enhanced Features

NetStorm

File Parameter Run Time Changes (RTC)

This feature provides ability to provide test data at run time. User can add/replace test data as needed during the running test.

There are following modes available:

• Append Mode: Append mode is used to add data lines in given Test Data file.
• Replace Mode: Replace mode is used to replace all data lines in a file with new data lines.

IPv6 Script Support

IPv6 support is now made available in 4.1.6 because of which users can now use IPv6 IPs for load generation.

Scenario Group Based Test Metrics

This release provides feature to enable scenario group based test metrics. If enabled, all the Test Metrics except Transaction stats and Transaction cumulative graphs can be seen group-wise.

File Distributions among NVMs using extension

In this release, the file extension concept has been added to validate the mode used in file parameters in order to avoid common mistakes of using incorrect mode. For example, if mode is unique, then file extension of “.unq” will enforce that unique mode is used.

Following extensions are to be used for different modes:

• For UNIQUE mode the file extension should be .unq.
• For SEQUENTIAL mode the file extension should be .seq.
• For RANDOM mode the file extension should be .ran.
• For WEIGHTED RANDOM mode the file extension should be .wtr.
• For USE ONCE mode the file extension should be .use.

Group based Ramp Down Method

Ramp down method scenario settings have been enhanced to control at scenario group level.

Inline Include Domain Pattern

This release provides feature that allows user to “Auto fetch” only the provided domain URLs and ignore the rest.

RBU_ORIGIN_DOMAIN

This release provides feature that whatever domain/pattern is provided is displayed under my domain list and the rest of the domain / patterns are displayed under third party.

NetDiagnostics

Node.js Agent

Cavisson Node.js is a JavaScript based agent for instrumenting Node.js application. Going forward users can monitor performance metrics from Node.js application to the operating system in real time, including response time, CPU utilization, disk I/O, slow web service calls, slow SQL calls, memory etc. Besides this, users also get visibility into backend services by auto instrumenting and gathering performance metrics for HTTP calls and metrics for supported back-ends like Redis, MySQL, PostgreSQL, Cassandra, etc.

Java Agent Features & Enhancements

• Exception/Error capturing in Integration Point calls

Business Transitions fail due to Error or Exception generated in Application while processing these transactions. Enhancements have been done in Java Agent with respect to capturing exceptions occurred in third-party applications while processing business transactions.

• HTTP Cookie based Condition Monitor

Now HTTP cookie can be used in the condition monitor. Prior to rel 4.1.6, user could capture counter of HTTP headers only, but from this release onwards, user can capture flow path of specified HTTP header.

• HTTP Header based Business Transactions Naming Rule

The user can configure business transaction names based on HTTP headers as well as URL query parameter name.

DDR Feature & Enhancements

• In Hotspot screen, user can see integration point calls and integration points detected for specific hotspot.
• NetDiagnostics compare report for Method timing and SQL queries.
• Performance enhancement in Method Timing report results in accelerated output.

Web Dashboard

Cavisson Web Dashboard offers extremely powerful analytics and visual representation of the testing as well as production monitoring data. Web Dashboard is an HTML5 based application which can run on all modern browsers, platforms and devices (like laptops, tablet, and mobile) as a responsive light-weight web client for numerous Cavisson products such as NetStorm, NetDiagnostics as well as NetCloud. Web Dashboard supports all features of the existing dashboard (classical).

New features introduced:

• Widget based UI
• Different types of Widgets
• Layouts
• Colour Themes

Load Based Alert

Load index based alerts or adaptive alerts is a mechanism to get rid of false alarms and configure meaningful alerts. For example, if load (PVS or request/sec) increases, normally the metrics like CPU and Response time also increase, and hence the baseline for CPU/Response time should be created as per the load value to avoid false alerts.

Load indexed based baseline learns the system behavior for all loads

• All System parameters – System/Network/Application parameters learned for different various Page View Per Second Load
• Average values over last 90 days

TCP Dump

TCP Dump is a most powerful and widely used command-line packets sniffer or package analyzer tool which is used to capture or filter TCP/IP packets that received or transferred over a network on a specific interface.

This release provides feature for taking TCP dump on demand using Web Dashboard for any of the servers in the topology, which will help in diagnosing network related problems.

Import Access Logs

An access log is a file or a combination of files that contains a list of all user interactions or accesses made to the server. Access log files are stored on a server with structure specific to a server type. For example, access log for WebLogic may have different structure than access log for Tomcat or any other application server. During load testing, access log data can be imported and merged in test-run data. This data can then be analyzed for numerous metrics and visually represented to gather meaningful decision-making information for diagnostics purposes.

Reports Enhancement

• Hierarchical Report: This report is based on the meta data component. There will be multiple drop-downs up to maximum level of hierarchy in test run.
• Stats Report: This report is used to view metrics data in tabular format.
• Additional Chart Types like Pie/Dial/Area etc. have been included.
• Reuse of measurements of generated reports to generate another report.
• Report Generation from Dashboard: Reports can be generated directly from the visible graphs or the graph data from the lower panel.
• HTML/Word options are now available in compare report.

Monitoring Features & Enhancements

Add new server at Runtime

From this release onwards, new server can be added at runtime.

New Monitors

Following new monitors have been added:

• Apache nifi
• MySQL
• Oracle database
• RabbitMQ
• Kafka Stats
• Tomcat Stats
• Cloudant
• Apigee Stats

Features Not Supported / Discontinued with 4.1.6
