    New authentication option

    In addition to IT Data Analytics, you can now use BMC Atrium Single-Sign On for authentication of users. Using this authentication is recommended if you want to use IT Data Analytics in conjunction with BMC TrueSight Presentation Server.

    For more information, see User authentication options.

    With this support, user authorization is handled differently. The following table describes the changes in the user authentication approaches.

    Version 2.0 and earlierVersion 2.1 and later
    • Users are mapped to both user groups and roles.
    • User groups are mapped with users only.
    • Users are mapped to user groups.
    • User groups are mapped to roles.

    Easy data pattern creation

    Version 2.1.00 provides you the capability of creating a data pattern by using a simple wizard that automatically identifies the:

    • Date format – Based on which the date and time string is extracted.
    • Overall pattern – Based on which the fields are extracted.

    To create the data pattern, you need to run the wizard and provide sample data from your data file. The wizard automatically detects the date format based on the sample data. You can even customize this format. After looking at the date format, you can choose to directly save the data pattern or perform advanced field extraction. For more information, see Creating data patterns.

    Editing and cloning of data patterns is supported in the same way as previous versions of the product. For more information, see Editing or cloning data patterns.

    Enabling data collection continuity

    You can now enable redundancy for data collection by including the Collection Stations in one common pool.

    Redundancy can help in scenarios where the Collection Station goes down or fails for some reason. In such a scenario, the Collection Agents communicating with that Collection Station are redirected to the other Collection Stations operating in the same pool.

    Thus, redundancy can minimize losing data mid-way when the Collection Station goes down. For more information, see Data collection redundancy.

    Comparing results

    You can now compare search results not only across different time contexts, but also against a different search query.

    Also, the UI for comparing results has been simplified for a better user experience.

    You can compare results in the following ways:

    • Specify a different search query and compare results for the same time context but against a different search query.
    • Select a compare option to compare results across different time contexts, but against the same search query.
    • Specify a different search query and select a compare option to compare results across both different time contexts and different search queries.

    For more information, see Comparing results.

    Collecting all kinds of Windows events

    You can now collect all kinds of events (or logs) configured in your Windows environment. This means while creating the data collector, you can select all the log types that you want to collect and analyze. Note that to be able to collect all kinds of events, you need to use version 2.1.00 of the Collection Station (or Collection Agent). If you continue to use an Agent from an earlier version, then you can only collect the Application, Security, and System logs.

    You can collect events both locally and remotely. To enable remote event collection, you need to perform some configuration steps. These steps vary as compared to the earlier release and based on other factors such as, whether you want to use a Windows or Linux computer as your collection host. For more information about the various factors and the configuration steps, see Configurations required before collecting Windows events.

    Capability for collecting log4j output into IT Data Analytics

    You can collect log4j output directly into IT Data Analytics over the TCP or UDP protocol.

    To do this, you need to add the SyslogAppender in the log4j .properties file that you want to collect and then create the Receive over TCP/UDP data collector.

    For more information, see Use case for sending log4j output directly into IT Data Analytics.

    New field types

    You can use the following new field types to save decimal floating point field values.

    • DOUBLE
    • FLOAT

    This feature can help you run statistical operations such as finding the minimum (or smallest) value, maximum (or largest) value, average of values, and so on. This can done by running statistical search commands such as stats and timechart.

    These field types can be assigned at the time of planning the fields that you want to extract, at the time of creating a data pattern.

    For more information, see Understanding field types.

    Search tools

    While specifying the search criteria, you can use search tools for selecting certain default fields and the tags present in the system. This capability helps you search more effectively and find exactly what you are looking for without knowing the exact search syntax.

    Additionally, this capability simplifies your search syntax and avoids the need for specifying a long and complex search string (especially while running search commands).

    Note: Search tools do not provide a way of changing any search settings like changing the number of results per page or changing the maximum number of results to export.

    For more information, see Filtering your search results.

    Search performance improvements

    Compared to previous releases search command combinations listed in the following table produce better results. Earlier, these search command combinations produced results that were limited to a particular value. This value is determined by the value of the search.events.fetch.limit property located in the searchserviceCustomConfig.properties file.

    For more information, see Modifying the configuration files.

    The following table provides search command combinations that produce better results:

    Search command combinationsExample search queries

    The filter command succeeded by one or more of the following commands:



    * | filter isNotNull(ResponseSize) |
    filter match(RequestType,"GET")|
    filter regex(ClientIp, "10\.1\.1\..*")
    * | filter isNotNull(ResponseSize) |

    Tabular search results

    In addition to the Text View and Chart View, a new Table View is available, that displays search results in the table format. In the Table View, each column in the table represents a field, while each row represents the individual record (or event) categorized into columns based on fields.

    This capability enables you to read and understand your data better. It also enables you to easily identify important portions of the data represented in the form of fields. Furthermore, you can control the number of fields (represented as columns) that must be displayed in the table. You can even resize the columns, add particular portions of the data to your search criteria and, add field names to the Filters panel.

    Notifications with multiple conditions

    This feature allows you to select multiple saved searches and define a condition for each saved search.

    This condition defines the number of results based on which the alert is triggered.

    Furthermore, you can define a high-level condition (operation) by which all the conditions (AND operation) or either of the conditions (OR operation) must be used to decide whether the alert must be triggered.

    Notes

    • This feature is only applicable for configuring alerts and not reports.
    • The Administration > Notifications page no longer displays information regarding the saved search, search string, and the number of results configured while creating a notification.
