Introduction

• Instead of the plain old tabular visualization in report files, users can add a more lively visual design to their Excel® reports by using the Import Excel Module (3rd-party).
• Reports start as usual with data in rows and columns, however, with the a choice of colors, Pivot Tables, and Charts a design is available that suggests , designs can be developed that provide better visualization and better decision making.

Use Cases

The PowerShell CLICommand Line Interface 2.0 is used by jobs to extract data and to create better designed reports. Two modules are applied for this purpose:available for designing better reports:

• The JS7 - PowerShell Module,
• A
• the JobScheduler PowerShell Module
• a reporting PowerShell Module. This example makes use of the ImportExcel PowerShell Module that (3rd party) which can be used to create Excel® reports and to add Pivot Tables and Pivot Charts to reports. The module can be operated for Windows and Linux computers and does not require prior installation of Microsoft Excel®.

Explanations: 

• Line 2-31: The job is executed with a Windows Agent that is assigned by a process class. The job is of type "PowerShell" and will use the PowerShell version provided with the serverand makes use of the PowerShell shebang for Windows.
• Line 3-4-5: The required PowerShell modules are imported. They could be installed in any location in the file system.
• Line 6-7: The Connect-JSJS7 cmdlet is used to authenticate with the JOC Cockpit JS7 REST Web Service API. The required URL and credentials are specified in a PowerShell profile, see PowerShell CLI 1.2 - Use Cases - Credentials Managementarguments for -Url , -Credentials and -Id can be specified in a number of ways:
  • As described in the JS7 - How to connect to JOC Cockpit using the PowerShell Module article.
  • Using JS7 - Job Resources that inject environment variables to the PowerShell job.
  • Using a PowerShell profile.
• Line 10: The Get-JS7TaskHistory cmdlet is invoked:
  • with the -Timezone parameter to specify the time zone which date values in the report should be converted to. The -Timezone (Get-Timezone) parameter value specifies that the time zone of the Agent's server is used. Otherwise specify the desired time zone, for example like this: -Timezone (Get-Timezone -Id 'GMT Standard Time'). Without using this parameter any date values are stored in the report as UTC dates.
  • optionally with additional parameters, for example, to specify the date or date range which the report is created for. A value -RelativeDateTo -3d specifies that the report should cover the last 3 days (until midnight). Keep in mind that dates have to be specified for the UTC time zone. Without this parameter the report will be created for the next day.
  • see the Get-JS7TaskHistory cmdlet for a full parameter reference.
• Line 11-20: From the output of the Get-JS7TaskHistory cmdlet Line 10: Create an object $reportData from the output of the  Get-JSTaskHistory cmdlet in which a number of properties are selected and are specified for the sequence in which they should occur in the report. 
  • To add more appropriate column headers the property names are mapped to a more readable textual representation.
  • Consider the handling of date formats in lines 16-20. The use of the Get-Date cmdlet converts the output format of dates (not the time zone) to the default format which is in place on the Agent's server. Without using the Get-Date cmdlet, any date values will be stored in the report in ISO format, e.g. 2020-12-31 10:11:12+02:00 for a date in the European central time zone that is UTC+1 in winter time and UTC+2 in summer time.
  • Line 18 introduces a new property, a calculated duration. From the start time and end time values of a planned start the difference in seconds is calculated and is added to the report.
• Line 22Line 21: The location where the Excel file will be saved stored is specified with the $xlsxFile variable.
• Line 2324: Create a variable $workSheetName that which is used to store the name of the worksheet.
• Line 2526-3031: Creates a spreadsheet and passes on the Excel Package object which provides the reference to the workbook and turns to the worksheets inside it.
  • $xlsxFile stores the path of the Excel® file.
  • If we you are updating an existing worksheet and the new data wouldn’t completely cover the area consumed by previous data, then we you may be left with “ghost” data. To ensure this doesn’t happen, we you can use the  -ClearSheet option to remove previous data in a worksheet.
  • -PassThru returns the Pivot Table so it can be customized.
  • -AutoSize parameter allows us you to resize the columns of the spreadsheet to fit the data added and to get the column-widths right.
  • For adding color to conditional text  -ConditionalText is used. Additional types of conditional format are supported. Here we use conditional text is used for the job status color like (successful=green, incomplete=orange, failed=red).

  • To assign a name to the worksheet the -WorksheetName parameter is used. The default name of the worksheet is sheet1.

  • The -IncludePivotTable and -IncludePivotChart parameters generate the Pivot Table and Pivot Chart. The parameter -ChartType lets you pick what type of chart you want to use, there are many examples to choose from: Area, Line, Pie, ColumnClustered, ColumnStacked100, ColumnClustered3D, ColumnStacked1003D, BarClustered, BarOfPie, Doughnut, etc.
  • The -PivotRows and -PivotData parameters describe how to tabulate the data.
• Line 3435: The -PivotTableName parameter is used as the name for the new Pivot Table.
• Line 35: By default, a Pivot Table will be created in its own worksheet, but it can be created in an existing worksheet. In the above job example the $excel.$WorkSheetName.cells["K1"] parameter defines the cell in an existing worksheet where the pivot table will be created.
• Line 3637:  $excel.$WorkSheetName refers to the worksheet in which the source data are found.
• Line 3738: The -PivotRows parameter is used for fields to set as rows in the Pivot Table.
• Line 3839: The -PivotData parameter contains a hash table in the form "FieldName"="Function," where a function is one of Average(), Count(), CountNums(), Max(), Min(), Product(), None(), StdDev(), StdDevP(), Sum(), Var(), VarP().
• Line 3940: To apply a table style to the Pivot Table the -PivotTableStyle parameter is used. The PivotTableStyle “Medium6” is the default table style but there are plenty of others to choose from. Example: PivotTableStyles = None, Custom, Light1 to Light21, Medium1 to Medium28, Dark1 to Dark11"..
• Line 48: The Disconnect-JS7 cmdlet is used to close the connection to JOC Cockpit.

Chart

• There is a sample Pivot Chart created with the parameter -ChartType ColumnClustered3D.
• This chart type is used in this example to display the number of jobs per state (successful, incomplete, failed, planned) of jobs.

Sample Pivot Table

...

• The sample Pivot Table displays the RowHeaderCaption as "By JobScheduler ID, Job, Status". You Users can adjust the style of the table by use of the parameter -PivotTableStyleusing the  -PivotTableStyle parameter.
