The Performance Reports Designer

The Performance Reports Designer allows you to see a visual representation of QoS data. You select the host, QoS measurement, target, and time range, and the data is displayed as a chart. You can display multiple measurements on a single chart, and can view multiple charts at a time. You can drag charts between rows or can drag a data series from one chart to another. You can select the chart format (line, area, or column chart), and the Filters tab allows you to plot only the data that matches specified filters on the chart. You can easily change the source (host or target) of the data by using the Choose Source menu. You can save a set of charts as a report to print or to view later. The import and export features allow you to share charts with other users.

If you do not have the QoS Access permission set in the ACL, you will see a "Permission Denied" message when you try to run the Performance Reports Designer application.
Beginning with CA UIM 9.0.2, Tomcat running in the wasp probe is upgraded for increased security. As a result URLs, including bookmarks for performance reports, containing certain characters (specifically:
{, }
, and
) may not be read properly. To avoid this issue, run new URLs through a URL encoder utility. If you experience problems with bookmarks created in previous versions of the product, run these through a URL encoder and resave them.
Understanding Performance Data
Performance Reports Designer can use either raw (unintervalized) or intervalized data. For intervalized data, a data aggregation interval is automatically selected based on the scale of the chart you are viewing. You can also choose an aggregation interval for the chart. Possible intervals range from one minute to one day.
The unintervalized data option ("none") replaces the raw data option in Performance Reports Designer in CA UIM 8.47 and later.
For an automatically selected interval, the timeframe of the data and resolution of your screen affects the scale. Performance Reports Designer selects the smallest aggregation interval so that there is only one data point per pixel. If there are multiple data samples for an interval, the values are averaged. For example, if the data is sampled every 5 minutes but the Performance Reports Designer chart is displaying 15-minute intervals, there are three data samples per interval. In this case, the average of the three data samples is displayed in the chart.
You can view the minimum and maximum values used in calculating each average by selecting the
USM line chart
format (USM Line Chart Icon) for any data series in a chart. The shaded area above and below the line shows the range of values used in calculating the average. A pop-up tooltip appears when you hover over a data point on the line, displaying the minimum and maximum values averaged for that point.
If there are fewer data samples than intervals, Performance Reports Designer displays interpolated data. For example, if the data is sampled every 15 minutes but Performance Reports Designer is displaying 5-minute intervals, two of the three data points for each interval are interpolated. If data is interpolated, when you mouse over a data point in the chart, the data tooltip labels the number as
rather than
. If you stack multiple data series on a bar chart and one data series has fewer data samples, you see shadow columns for interpolated data: this allows you to stack a denser data series on top of a sparser one.
For bar charts, each column displays data for five times the interval for the chart. For example, if the chart is using 1-minute intervals, each column represents 5 minutes.
If data is missing, it is not estimated. The chart will display a gap where missing data occurs.
You can export either unintervalized data or intervalized data for Performance Reports to a CSV file.
Selecting a Data Aggregation Interval
You can accept the default data aggregation interval for a chart or select a different interval from a menu. On creating a new chart, the lower-left corner will show the current data aggregation interval. The default data aggregation setting is Automatic, resulting in an aggregation interval based on the report time frame and the width of the window in your browser. You can select a different interval from the pull-down menu. Options range from one minute to one day and
. The
option indicates that no aggregation is applied and all performance data is displayed in the chart.
All series in a chart and all charts in the report use the selected aggregation interval. If you change the aggregation interval for a report, all charts and data series inherit the new interval.
The following conditions apply to data aggregation intervals for a Performance Report:
  • Multiple unintervalized data series for a chart cannot be stacked (summed). The
    option in the
    (Configuration Icon) menu at the upper left will be greyed out if the
    intervalization option is selected.
  • A new chart in a report will inherit the existing data aggregation interval.
  • The selected data aggregation interval for charts is saved in the performance report.
  • When exporting chart data to a CSV file, you can save the unintervalized data for the report or save only data for the selected aggregation interval.
Report Scheduler honors the interval in a performance report, but you can change the interval in Report Scheduler. In this way, you can produce reports with different intervals from the same file. The resulting PDF displays the interval selected.
QoS Selection Tabs
The QoS Selection tabs are where you can select the host, QoS measurement, and target you want to view data for. There are two QoS Selection tabs: the QoS Selection by Host tab and the QoS Selection by Target tab. The two tabs function the same way, but the order in which you select hosts and targets is different.
  • QoS Selection by Host
    - Use this tab to find multiple measurements from the same host
  • QoS Selection by Target
    - Use this tab to find measurements of the same type on multiple hosts
The selection panes have the following fields:
Host name of the computer you want to chart measurements for.
Type of QoS measurement you want to chart.
Which measurement, if more than one measurement for the selected QoS type is taken. For example, for CPU usage you can select Idle, System, User, Wait, or <host name>.
Work from left to right in the selection panes. Enter text in the filter field at the top of each selection pane to display only items that contain that text.
To select a measurement for charting in the QoS Selection by Host tab, for example:
  1. In the Host pane, select the host name of the computer you want to chart measurements for. Once you select the host, the QoS measurements for tests you are running on that host are listed in the QoS pane.
  2. In the QoS pane, select a QoS measurement. Once you select a QoS measurement, the available targets are listed in the Target pane.
  3. In the Target pane, select a target, then drag it to a chart pane to display it.
    You can drag multiple targets to each chart. If the targets are measured in different units, a second y-axis is added on the right side of the chart. You can add as many targets with the units on the two y-axes as you want, but you cannot add a target with different measurement units. For example, if the left y-axis represents percent and the right y-axis represents seconds, you can add an unlimited number of targets that are measured in percent or seconds but you cannot add a target that is measured in megabytes.
Filters Tab
The Filters tab is where you can create filters to narrow the data to be charted. Once you enter your filter options, check the results with the Check Filters button to see that the results are not too broad and then drag the drag bars to a chart. Charts update dynamically at a regular interval to reflect changes in the search results.
The Filters tab has the following fields:
Field or Button
Enter a name for the filter.
Check Filters
Displays the items that match the filter in the pane to the right. Use this to ensure the filter is narrow enough that you do not bog down your system charting a huge amount of data.
Applies changes to the filter to the currently displayed charts.
Drag bars
Drag bar icon
Drag these bars to a chart to graph the results for the filter.
Add filter

The following table shows how to enter special characters for each database type.
You might need to enclose the special characters '\', '%', and '
in escape characters when you use basic search or advanced search or when you apply filters in USM or in PRD. In the case of advanced search and filters, this requirement applies when the
starts with
, or
ends with
operator is selected. The required escape character depends on the type of database. For MySQL, the backslash (\) is the escape character; for MS SQL, special characters are enclosed in square brackets ([ ]). Searching for special characters is not supported for Oracle.
Not applicable
\ (No escape character required)

User Tags
You can filter on two user-defined criteria, named User Tags, in portlets that have filters. You can also automatically create groups according to User Tag.
User Tag 1
User Tag 2
are text fields that are defined on the robot. You can enter any text in these fields. (Use Infrastructure Manager to open the configuration window for the robot.) Once you have done so, you can filter for these values in the Unified Service Manager, Performance Reports Designer, and List Designer portlets.
For example, you could use
User Tag 1
for geographic location (such as
)  and
User Tag 2
for type of server (such as
production server
web server
). You can then create reports for your regional systems by filtering on
User Tag 1
in the Performance Reports Designer (in the
tab) or List Designer (in the filter fields of the
New Group
pane). To do so, you would set the filter to
User Tag 1 is Europe
User Tag 1 is Asia
Performance Reports Designer Window
In the Unified Service Manager portlet, you can create separate groups for your production servers and for your web servers and then apply different monitoring templates to them. To create the groups, in the
section of the Edit Group dialog you would set the filter to
User Tag 2 is production server
for one group and
User Tag 2 is web server
for the other group.
Filters Section in the PerformanceReportsDesigner
User Tag 1
User Tag 2
can be used to filter for any system that has a robot running on it. You cannot use
User Tag 1
User Tag 2
to filter for network devices that do not have a robot.
Charts Pane
The charts pane is where you can view the data for the selected host, QoS, and target. You can select the chart format, maximize the display, or adjust the data range for the y-axis. Hover over a data point to display information about the data in a pop-up window. You can drag charted data to move it from one chart to another. For a line chart, for example, click on a line and drag it to another chart.
To zoom in on an area of a chart, drag the cursor to select that area. Repeat to zoom in again. Click the graph to zoom out all the way. Drag the cursor to select a portion of an axis to zoom in on the selected range.
The charts have the following fields and icons at the top and upper left:

If you have selected a single target for multiple hosts (QoS Selection by Target), clicking this displays a list of targets for the selected QoS measurement. This allows you to view different measurements for the same hosts.
The menu bar displays the name of the current host or target. If there are no other corresponding hosts or targets, the combo box is not displayed.
Configure Icon
Click to display a pop-up menu with the options below.
  • Stacked
    - Stacks the data series on top of each other. This option is not available for displaying unintervalized data.
  • Legend
    - Toggles the display of the legend on and off. The legend, which appears at the bottom left of the chart, displays the host/QoS/target for each data series in the chart.
  • Title
    - Adds a title to the chart. Double-click the word Title at the top of the chart, enter your text, and press the Enter key. Change the title at any time in the same way.
  • Info text
    - Adds descriptive information to the bottom of the chart. Double-click the words Info text, then enter your text.
  • Trend Line
    - Displays a trend line for the data. If you hover over a data point on the chart, the trend value for the data point is included in the tooltip.
  • Baseline
    - Displays baseline data, if available, as a dotted stair-step line. If you hover over a data point on the chart, the baseline value for the data point is included in the tooltip.
  • Percentile
    - Adds a line marking a specified percentile to the chart. Enter the percentile in the spinner box.
  • Scale
    - Adds a scale factor to the selected data series. For example, a scale of 2 doubles the values of the series. Once you select Scale from the pop-up menu, a text box is displayed on the title bar where you can enter a number for the scale factor you want.
Pop-up tool tips present relevant information on data points in the chart. So, for instance, the tool tip shows minimum and maximum values averaged for intervalized data points, and tool tips for stacked bar charts show the value of each component and its percentage of the whole.
The charts have the following icons at the upper right:
Maximize Icon/Restore Icon
Click to remove the data series selection pane and maximize the chart area or to restore the data series selection pane.
Export CSV data
Export CSV Data
Click to export the chart data in CSV format.  The dialog displays the number of chart series and total data points for the chart. You can select a link to copy the csv formatted chart data to the clipboard, or select a button to download and save the data.  You have the option to select an aggregation value of “None” in order to display all data points instead of the aggregated data points displayed in the chart. Please note:
  • If no aggregation interval is selected for the charts, the only option is to export the unintervalized data as it appears on the chart.
  • If the “Automatic” data aggregation is selected for the charts, the aggregation value for export is the actual calculated interval used in the chart.
  • If a different aggregation interval is required for the CSV data export, change the aggregation setting for the charts then click the export button again.
The Chart CSV Preview dialog displays the first 10 records so that you can preview the data. From the dialog options, you can save the data to a file or copy it to the clipboard.
Only actual data samples are included; interpolated data (for intervals that are missing data) are not included in the CSV file.

Data range
Data Range
By default, the y-axis displays the range of data values plus or minus 5 percent. For example, if the data values range from 40 to 80, the y-axis displays a range of 38 to 84. However, for some data units, such as percentages, you might prefer to see the data displayed at a different scale. Click the Down Arrow Icon button to set the baseline of the y-axis to zero, and click the Up Arrow Icon button to set the top of the y-axis to 100 percent. The buttons appear next to the left or right y-axes if appropriate for the data units. If the data unit is percent, for example, the top and bottom buttons are displayed. If the data unit is megabytes, however, only the bottom data range button is present.

  • Start/end date fields- Useful for charting a specific time period. Click to display a calendar, where you can select the start or end time for the data you want to chart. If the end time is the current time or is in the future, the word Now is displayed in the date box and the charts are updated at 1-minute intervals.
  • Date and time sliders - Useful for browsing the same time period on different days. Set the sliders from left to right. The slider on the left lets you select the level of granularity you want (year, month, day, or hour). Once you select, the middle slider lets you select which year, month, day, or hour you want to chart. Once that is selected, the right-hand slider lets you select a period within that year, month, day, or hour. For example, if you are viewing data for 3 to 5 p.m. for the current day and want to view data for the same time the previous day, move the middle slider to the left one increment. (If you are viewing data for a specific day, the slider on the left is already set to Day.)You cannot move the sliders beyond the increment for the current time.
  • Quick View buttons - Useful for viewing data for common time intervals:
    Previous Hour Icon - Previous hour
    Previous Day - Previous day

Define Reports with a URL
You can use URLs with parameters to define reports from a browser without being logged into UMP. You might want to define reports without logging if you want to share reports with people who do not have UMP accounts, or to link to reports from a third-party application.
You can view reports as defined, and you can change parameters such as the source, QoS, target, or time period by specifying one in the URL. For example, if you have a report that is named "CPU that displays a series of CPU measurements, you can view the same measurements for a different computer system by specifying a different source in the URL.
You can define one or more data series for each chart, and you can have multiple charts in a row and multiple rows.
The syntax for the URL is:
If you omit the user and password, a box prompts the user for credentials.
The def parameter
The def parameter uses the JSON syntax, using single quotes rather than double quotes. The full specification can be viewed at
The JSON syntax is a set of key value pairs that are specified as {'key':value, 'key2':value2}.
All the options except time specifications are listed in an array to define sets of charts. Each set of charts is listed in an array to define a set of rows.
Normally the URL is specified in a single line. However, to make it easier to read these examples are broken into multiple lines.
Example - Multiple Rows
def= {'time':'-1hour','rows':[ {'charts':[ {'parms':"...", 'series':[ {'sqt':'myserver|QOS_CPU_USAGE|Total','scale':'1','color':'8000','style':'line'}, {'sqt':'myserver|QOS_CPU_USAGE|User','scale':'1','color':'800000','style':'line'} ]}, {'parms':"...", 'series':[ {'sqt':'myserver|QOS_CPU_USAGE|Total','scale':'1','color':'8000','style':'line'}, {'sqt':'myserver|QOS_CPU_USAGE|User','scale':'1','color':'800000','style':'line'} ]} ]}, {'charts':[ {'parms':"...", 'series':[ {'sqt':'myserver|QOS_CPU_USAGE|Total','scale':'1','color':'8000','style':'line'}, {'sqt':'myserver|QOS_CPU_USAGE|User','scale':'1','color':'800000','style':'line'} ]}, {'parms':"...", 'series':[ {'sqt':'myserver|QOS_CPU_USAGE|Total','scale':'1','color':'8000','style':'line'}, {'sqt':'myserver|QOS_CPU_USAGE|User','scale':'1','color':'800000','style':'line'} ]} ]} ]}
To define a single row, you can omit the 'row' option.
Example - Single Row
def= {'time':'-1hour', {'charts':[ {'parms':"...", 'series':[ {'sqt':'myserver|QOS_CPU_USAGE|Total','scale':'1','color':'8000','style':'line'}, {'sqt':'myserver|QOS_CPU_USAGE|User','scale':'1','color':'800000','style':'line'} ]}, {'parms':"...", 'series':[ {'sqt':'myserver|QOS_CPU_USAGE|Total','scale':'1','color':'8000','style':'line'}, {'sqt':'myserver|QOS_CPU_USAGE|User','scale':'1','color':'800000','style':'line'} ]} ]} }
Similarly, you can omit the charts parameter if you only have one chart.
Strings are enclosed in single quotes.
For a URL, certain characters, including single quotes, must be properly escaped:
  • Single quotes are written as \\\' or \\'
  • The ampersand (&) is written as _amp_
  • The backslash is written as \\\\
Numbers are written in numerals.
An array is a set of JSON objects enclosed in brackets.
For <boolean> 'y', 'yes', 1, 't', 'true', true, or 'on' can be used for
. For
, you can use 'n', 'no', 0, 'f', 'false', or 'off'.
The time frame must be specified at the top level of a report definition:
  • 'time'
    - Time parameters for the report.
    • <epoch> is a specific time in seconds since epoch
    • <period> is a time period supporting the units "sec", "min", "hour", "day", "month", "year". For example, "60min" or "2hour"
    Time can be specified as follows:
    • '<epoch>-<epoch>' - start time to end time
    • '<epoch>-' - start time to now
    • '<epoch>-<period> - the <period> leading up to <epoch>
    • '<epoch>+<period> - the <period> after <epoch>
    • '-<period>' - the last <period>. For example, '-60min' shows the last 60 minutes.
You can choose a data interval for display in a graph or chart:
  • '
    ' - Use with a value for the data interval in seconds. Valid intervals are:
    • 0 (no aggregation)
    • 60 (1 minute)
    • 300 (5 minutes)
    • 900 (15 minutes)
    • 1800 (30 minutes)
    • 3600 (1 hour)
    • 7200 (2 hours)
    • 14400 (4 hours)
    • 28800 (8 hours)
    • 43200 (12 hours)
    • 86400 (1 day)
      Any other value sets the aggregation interval to "Automatic," and the displayed data interval is determined by the chart width on loading the data. See the section
      Understanding Performance Data
      for an explanation of this function.
You can set a flag for getting the raw data:
  • 'rawData'
    - Use with a value of
    to see the data in CSV format instead of a graph or chart.
    Setting the
    parameter to
    overrides any defined data aggregation interval. With
    set to
    , wildcard characters can be used to select data series for inclusion.
A report consists of some number of rows of charts. If a single row of charts is desired, the
parameter might be omitted:
  • 'rows'
    - An array of row definitions. A row contains one or more charts.
  • 'charts'
    - An array of chart definitions. A chart contains one or more series.
The parameters for a chart are:
  • 'title'
    - Title of the report. If omitted there is no title.
  • 'info'
    - Informational text displayed at the bottom of the chart.
  • 'tref'
    - Time reference. If a time is specified, you can highlight a time or a time period.
  • '<epoch>+-<period>,[<epoch>+-<period>]
    ' - Start and stop of the highlighted period (stop is optional). "S" for epoch is the chart start time. "E" is the end time.
    'tref':'S+10min,E-1hour' highlights the area from 10 minutes after the chart starts to 1 hour before it ends.
  • 'stacked'
    - <boolean> Stacks the series for the chart.
  • 'lmax'
    - Sets the maximum value for the left axis.
  • 'lmin'
    - Sets the minimum value for the left axis.
  • 'rmax'
