21st May, 2020 – Release Notes 4.2.1.44

New and Enhanced Features

NetStorm

  • TestSuite / Jenkins Enhancements
    • Supports new options including Whole scenario, Absolute time, Elapsed time, and Phase for selecting a time period in NS-ND plugin.
    • Allows Decimal and Zero values for defining the critical threshold value, warning threshold value, and overall fail criteria. Decimal is limited to two places only.
    • Allows you to send TestSuite Reports from NetStorm. Using the new Mail Configuration tab, you can configure email settings, select the ‘Send Report as Attachment’, and provide To, Cc, and Bcc fields.
    • Allows you to specify the ‘Threshold As Range’ option as required for each check profile being added in the test case by using a toggle switch present adjacent to each profile in the test case.
  • RBU Enhancements: Enhanced the ability to handle page failures cases by providing the Page Availability matrix, which will be zero in case of page failures, such as 4XX, 5XX, CVFail, ConFail.

Dashboard

  • Enhanced Dashboard Performance: This release boosts the data loading performance of the Dashboard by offering the following enhancements:
    • Quick rendering of data into the widgets and getting displayed in the desired format is the key enabler for performance improvement.
    • Data marked as favorite is now loaded on the dashboard in chunks, where the favorite panel/widget acts as a unit of chunk.
    • Minimized the data loading time in widgets as individual requests are sent for each widget.
    • Improved the sample update with regular time interval.
    • Faster loading of widgets with less data as compared to the widgets having large data.
    • Improved the dragging and resizing of graphs in Design mode.
  • Notification Support in Big Panda: This release supports the sending of notifications to the Big Panda tool:
    • Enables you to configure the Alert Action using the Big Panda extension to send notification.
    • Allows you to view the alert incidents in the Big Panda application.
  • Support for ACL and OKTA login System for ML Dashboard: Now, the Machine Learning (ML) Dashboard login system is more secure with the support of OKTA:
    • Access the ML Dashboard by using the ND login (for both OKTA and ACL).
    • User is redirected to OKTA or ACL login page, where login credentials are validated, before being redirected to ML Dashboard application.
  • Support for Alert Based Thread/Heap Dump in Analyzer: Prior to this enhancement, we were only able to take Thread/Heap Dump using Alert Action but we were unable to analyze it in UI. Now we are able to analyze the Thread/Heap Dump from Analyzer.
  • Logging Info Alert to Alert History through Custom Alert: While generating Alert using Rest API having Severity value as 6, then Info Alert is generated which can be seen in Alert History.

NetDiagnostics

  • Configuration UI: Dynamo Support
    • DB Entry Point Support: Support for the following Dynamo DB entry point:

com.amazonaws.services.dynamodbv2.AmazonDynamoDBClient.doInvoke(Lcom/amazonaws/Request;Lcom/amazonaws/http/HttpResponseHandler;Lcom/amazonaws/http/ExecutionContext;Ljava/net/URI;Ljava/net/URI;)Lcom/amazonaws/Response;|dynamoDB|1

    •  Callout Support
      • The Dynamo callout support is provided in Transaction FlowMap, Method Call Tree, and BT IP Summary Report.
      • Allows dynamo DB calls in Transaction FlowMap, MCT, and BT IP Summary.
  • Pagination Support for Thread Hotspot Request
    • Improved the overall performance of the displayed thread hotspot data.
    • Loads data in pages to reduce the time in rendering data.
    • A new request is raised whenever the user needs data for any page.

Monitors

  • Agentless Monitoring Support
    • Easily fetch data using SSH by providing remote server username and password or pass-phrase.
    • Eliminates the need of deploying machine agent on the server side to run any command based monitor.
    • Configure all monitors (Generic Command Based Monitors) on local agent to fetch data from remote servers.
    • Agentless monitoring support is available for Generic Command Monitors.

NetVision

  • Display of Page Details (by default): Supports the display of page details by default whenever a user clicks on any session.
  • Cluster Enhancement: Sync All Needed Configuration at the Time of Bind to Master: 
    • Provides the capability to synchronize the entire basic configuration itself, which will remove the error chances due to wrong or missing configuration.
    • Eliminates the need for manually configuring all the nodes in case of a cluster.

NetForest

  • Query Widget Support in Dashboard
    • Dashboard widget settings includes a new feature, which will fetch data from NetForest (NF) using NF REST APIs and display it on the Web Dashboard without opening NF UI.
    • The users do need not to login into NF to see the visualizations and data can be displayed in various formats, such as line, table, bar, and vertical line chart.
  • Java 11 Support (Log Agent and Machine Agent)
    • Provides support for Java 11 for NetForest.
    • Allows you to use Log Agent and Machine Agent both with Java 8 and Java 11 with all the existing features, such as pipeline monitoring, retry, reload, token-bucket etc.
    • Improves the overall performance.
  • Auto Suggestion
    • Supports the auto-suggestion feature to ease the search operation in query string.
    • Enables the user to search a virtually unbounded list for related keywords and phrases, which may or may not match the precise query string. For example if the user type any alphabet like ‘t’, then it should suggest all field starting with ‘t’, such as tier, type etc.
  • Add Reload for Linux Platform and creating systemd service U16
    • Implements the reload functionality and run application as a service in ubuntu.
    • Allows you to reload it using nc (netcat tool) from other machine in the same network and start NF-Forwarder as a service in ubuntu/linux machine.
  • Other Enhancements
    • Allows ‘Append’ query to be used with ‘Lookup’. Earlier, the maximum hits were 10000, which should be max 20000 as lookup was not working. After this enhancement, we are getting max 20000 hits for our query.
    • Introduces the nd-parse plugin at NFDB end to parse the logs, which is sent by ndagent. Earlier, we were using nfagent to parse and send data to nfdb. Now, nfagent is not required if ndparse plugin is present.
    • Supports only one search request at a time by disabling the search button till all the results are retrieved in the NFUI side.
    • Merges the ‘cmon.env’ and ‘nf.env’ files in a single file in ‘cmon.env’ to manage the configuration details in a single file. The naming convention and usage of all the environment variables are same as before.
