This documentation relates to the latest released version of BMC Discovery.
See the information on this topic for versions 11.2 or 11.1.

The custom reporting feature enables you to perform customization of the reports and channels on the appliance. Channels may be created more simply using the Channels page.

The following topics are covered in this section:

Configuration files

The reporting facilities and selection of UI channels shown on each page are configured using xml configuration files which are held in the following directories:

  1. /usr/tideway/data/installed/reports_content/
  2. /usr/tideway/data/custom/reports/

The directories are parsed in the order given (installed before custom), and the files contained in these directories are parsed in alphabetical order, with numbers before letters. This order is important as later definitions for a named report override those loaded earlier. The standard reports are contained in /usr/tideway/data/installed/reports_content/00reports.xml.

The configuration is read when the UI process starts. Changes to the report configuration files require a UI restart. Errors in the configuration files do not prevent the Application server from starting but might cause various reports and channels to be missing.

To get the UI to update with your custom reports, do the following:

  1. Log out of the UI
  2. From the command-line, as the tideway user, run this command:  
    tw_service_control --restart appserver
  3. Log back in to the UI.

On a cluster, you must update the 00reports.xml file on the coordinator and restart the cluster. See Shutting down and restarting clusters for more information.

You cannot add context sensitive reports to the discovery status page.

You cannot customize the Host Profile report.

The root element of each reports.xml file must be <reports version="2.0">. The <reports> element can have several types of elements:

<report> elements

A <report> element requires a name attribute giving a unique name to the report.

Tag

Details

Title

Provides the main page title for the report. This tag is mandatory.
<title>Hosts ordered by Host Owner</title>

Description

Populates the title attribute of the HTML link. Presented as a tool tip. Also shown as a subtitle in the following example the main page title. This tag is mandatory.
<description>Shows a list of all Discovery Hosts, ordered by their Owner</description>

Kind

Kind to use in search. Multiple kinds can be specified in a comma separated list or by using the * wildcard.
<kind>Host</kind>

Flags

Any flags to include in the search query. This tag takes an optional keyword attribute which, when given value False, prevents the addition of the FLAGS( prefix and ) postfix. The attribute is normally used if parameters are used control the flags.
<flags>include_destroyed</flags>

With

Any with functions to evaluate in the search query.
<with>value(NODECOUNT(TRAVERSE Host:HostedSoftware:RunningSoftware:SoftwareInstance)) AS si_count</with>

Where

Any conditions in the search query. This tag takes a couple of options attributes:

  • keyword which, when given value False, prevents the addition of the WHERE keyword when constructing the query. For example, TRAVERSE :::Host must not be prefixed by WHERE.
  • start which, when given value False, places the parameter conditions at the start of the query rather than the end. Normally parameter queries are added after the <where> text. However, if there is a need to perform tests before a traversal then they can be placed at the beginning.

    <where>version = ''</where>

Order-by

Sort results of query by specified order.
<order-by>name</order-by>

Show

List of attributes to display. This tag takes an optional keyword attribute which, when given value False, prevents the addition of the SHOW keyword.
<show>name, os, #InferredElement:Inference:Primary:HostInfo.hostid</show>

Url

Redirect browser when report is selected.
<url>NetworkMismatchSummaryReport</url>

Imports

List of <import> each of which contains a Python module to import. These are used by the <parameters> for <convert>, <default> and <eval> described in the following section.
<imports><import>common.timeutil</import></imports>

Parameters

List of <parameter> each of which contains an interactive parameter filled in by the user. These are described in detail in the following section.


<parameter> element

Interactive parameters are defined using <parameter> elements. They must have a name, representing the name of the parameter, that is unique in the report.

Tag

Details

Title

Label of the parameter shown when it is rendered in a form. This tag is mandatory.
<title>Start date</title>

Type

Type of control widget to use for the parameter in the form and is detailed in the following section. This tag is mandatory.

Key

References a replacement construct in the constructed query.
<key>from</key>

Where

Query fragment to add to where clause of the parent element's search string. The reports system inserts the value of the parameter using string substitution with a key of value.
<where>name HAS SUBSTRING %(value)r</where>

When the query is built from parameters all the parameters are evaluated as specified by <type>. If a parameter has a where clause it is substituted into the where clause with a key of value. All parameters without a key are then joined together using AND and inserted either at the beginning (<where start="True"> specified) or end of the where clause in the report. The complete query is then constructed. If there are any parameters with a key the completed query has those parameters inserted using string substitution with the specified key of the parameter.


The <type> tag must have a name attribute which specifies the type of the parameter. It should have one of the following values:

  • TextField: a text entry field.
  • SelectField: a list.
  • RelationshipSearchField: a popover node-selection field.
  • DateTimeField: a time field.

The tags that can be used with <type> depend upon these values.

Tag

Details

All

If type is SelectField add an All option to the select list (the default). When given value False prevents the addition of the 'All' option.
<all>False</all>

Convert

Function used to convert the default value and user-typed value for use in query. For example, the function could be common.timeutil.convertFromUnix. This will convert the value to UNIX form, which can then be added to the query. Referenced functions should be fully specified, and the packages and modules required should appear in <imports> elements, described in the previous section. Functions are referenced rather than called so do not need parentheses. The function can also be a lambda function taking one parameter.
<convert>common.timeutil.convertFromUnix</convert>

Default

Expression that defines a default value for the parameter. Referenced functions should be fully specified, and the packages and modules required should appear in <imports> elements, described in the previous section.
<default>common.timeutil.convertToUnix(common.timeutil.currentTime())</default>

Escape

Escape string value. By default string values are escaped. When given value False prevents the escaping.
<escape>False</escape>

Kind

If type is RelationshipSearchField is used to determine which source kind when finding a list of relationships defined in taxonomy.
<kind>Host</kind>

Size

If type is TextField specifies the size of the text field otherwise specifies the number of visible options in the list.
<size>2</size>

Options

If type is SelectField then there are several ways to specify the selection options:

  • eval which evaluates the expression. Referenced functions should be fully specified, and the packages and modules required should appear in <imports> elements, described in the previous section. <eval>api.audit.getEvents()</eval>
  • option which contains the option text. The <option> takes an optional value attribute which is used when the option is selected. If no value attribute is present the option text is used. Multiple <option> values can be provided.
    <option value="21">FTP</option>
  • query which performs a search query the first column of which is used as selection values. <query>SEARCH Location SHOW name</query>

    Only one of the selection option forms can be specified.

Validate

How to validate the parameter. Currently supports:

  • integer: value is an integer
  • number: value is a number
  • boolean: value is a boolean
  • NotEmpty: value is not empty

    If the value does not validate the form will present an error to the user.
    <validate>NotEmpty</validate>
Bringing all this together, the following element defines a parameter which appears in the UI labelled Type as a list with three specified values and no All entry. The <where> tag means that should the user choose Host then kind(#) = 'Host' will be added to the report query.


<parameter name="DQ_Report_Global_type">
   <title>Type</title>
   <type name="SelectField">
      <all>False</all>
      <options>
         <option value="Host">Host</option>
         <option value="SoftwareProductVersion">Software Product Version</option>
         <option value="BusinessApplicationInstance">Application Instance</option>
      </options>
   </type>
   <where>kind(#)='%(value)s'</where>
</parameter>

The following report will count the number of instances of software instances on host optionally limiting the software instances to a particular type chosen by the user from a list.

<report name="Software.Report.InstanceSummary">
   <title>Software Inventory</title>
   <description>Shows summary of distribution of a piece of software</description>
   <kind>SoftwareInstance</kind>
   <show>
      type AS "_|Type|_",
      product_version AS "_|Product Version|_"
      PROCESS WITH
         countUnique(1,0)
  </show>
  <parameters>
     <parameter name="Software_Report_InstanceSummary_type">
        <title>Product type</title>
        <type name="SelectField">
           <options>
              <query>
                 SEARCH SoftwareInstance
                 ORDER BY type
                 SHOW type
                 PROCESS WITH unique()
              </query>
           </options>
        </type>
        <where>type = %(value)s</where>
     </parameter>
  </parameters>
</report>

<chart> elements

The <chart> element in fundamentally the same as the <report> element with the following changes:

  • the default type of chart can be specified by adding the default attribute to <chart>,
  • the <show> tag is used to determine the click through columns of the chart.

Additional tags are:

Tag

Details

Split

Indicates the column to chart. This tag takes an optional columns attribute which specifies the number of columns generated by the split. For example,
<split columns="2">endtime PROCESSWITH bucket(3600, 3, 48)</split>
retrieves the endtime and puts the values into a list of buckets producing 2 columns, the time and the count. The title of the column is used as the axis title. A maximum of 2 <split> tags can be defined, the first for the x-axis, the second the y-axis.
<split>os AS 'Detailed OS'</split>

Y-axis-title

Indicates the title of the y axis column. This will default to Count unless the <split> provides a second column.
<y-axis-title>Hosts</y-axis-title>

For single columns the supported charts are:


  • pie (default)
  • bar
  • column

For two columns the supported charts are:

  • line (default)
  • column

The following chart will show a count of different OS classifications. By default a pie chart will be shown and when clicked through a summary report for the appropriate hosts. When displaying bar and column charts the y-axis will be labelled Hosts.

<chart name="Infrastructure.Chart.OSClassification" default="pie">
   <title>Host OS Classification</title>
   <description>Show count of Hosts for each OS Classification</description>
