14.36 PerfOverview

Use this Knowledge Script to generate a report containing a single average value for each selected datastream for a specified increment of time, for example, an average value derived from one hour’s worth of data or 30 days’ worth of data.

If you expect the data sets from which you are deriving values to exceed 1.5 GB, use PerfOverviewLD instead of this script.

A separate chart is generated for each selected datastream.

Parameter

How To Set It

Data source

Select data wizard

Select the data for your report by Knowledge Script or by datastream.

Select the style

Select the style for the first page of the report:

  • By computer provides links to pages showing the data collected from individual computers (each page shows all the datastreams collected from a single computer)

  • By datastream provides links to pages showing a side-by-side comparison of values for the same datastream collected from different computers (each page shows, for example, the value of the NT_CpuResource-All Threads(#) datastream from each computer)

  • By Knowledge Script provides links to pages showing all datastreams collected by a Knowledge Script (each page shows all datastreams collected from all computers on which the script has run)

Select time range

Filter the data for your report by a specific or sliding time range. The default is Sliding.

Select peak weekday(s)

Filter the data for your report by days of the week.

Aggregation by

Select the method by which data in the report is aggregated. The options are:

  • Minute

  • Hour

  • Day

This parameter is used in conjunction with the following parameter. For example, if you choose to aggregate by day, then the following parameter determines how many days’ worth of data are aggregated.

Aggregation interval

Select the interval at which the data in your report is aggregated. This parameter is used in conjunction with the previous parameter. For example, if the Aggregation by parameter is set to Day, use this parameter to set the number of days by which data is aggregated (1 gives you a single value for one day’s worth of data, 2 gives you a single value for two days’ worth of data, and so on).

Report settings

Include parameter help card?

Set to y to include a table in the report that lists parameter settings for the report script. The default is y.

Include table/chart/both?

Select the type of datastream values you want to include in the report:

  • Table (table only)

  • Chart (chart only)

  • Both (table and chart)

Select chart style

Define the graphic properties of the charts in your report.

Select output folder

Set parameters for the output folder.

Add job ID to output folder name?

Set to y to append the job ID to the name of the output folder.

A job ID helps you correlate a specific instance of a Report Script with the corresponding report.

The default is n.

Select properties

Set miscellaneous report properties as desired.

Add time stamp to title?

Set to y to append a time stamp to the title of the report, making each title unique. The time stamp contains the date and time the report was generated.

A time stamp allows you to run consecutive iterations of the same report without overwriting previous output.

The default is n.

Event notification

Event for report success?

Set to y to raise an event when the report is successfully generated. The default is y.

Severity level for report success

Set the event severity level, from 1 to 40, to indicate the importance of the event. The default is 35 (magenta level indicator).

Severity level for report with no data

Set the event severity level, from 1 to 40, to indicate the importance of the event. The default is 25 (blue level indicator).

Severity level for report failure.

Set the event severity level, from 1 to 40, to indicate the importance of the event. The default is 5 (red level indicator).
