The objective of the Citrix NetScaler ADC reports is to aid administrators in analyzing the usage trends of the NetScaler appliances in their organization, including any Load Balancers and Gateways running under the NetScalers.
For a selected time frame and selected appliances (NetScalers, Load Balancers, Gateways), the reports present data about past activity and performance, either individually for each appliance or in summary form for all selected appliances.
Three reports are available for this purpose:
- Citrix NetScaler ADC report
- Citrix NetScaler Load Balancing report
- Citrix NetScaler Gateway report
Figure 1: Citrix NetScaler ADC report
Examples of questions these reports are designed to answer are:
- Which NetScalers were available during the selected time period?
- Is the workload shared evenly among the organization’s NetScalers?
- Were there any configuration changes on our NetScaler appliances and, if so, when did they occur?
- Is NetScaler X itself causing bottlenecks?
- Should we add more capacity to serve the Load Balancers?
- How many requests does Load Balancer X usually handle during business hours?
- Are the Load Balancers traffic and behavior influencing user experience?
- How many users does Gateway X usually handle during a selected time period?
Sections of the NetScaler Reports
Each of these reports is composed of three sections:
- Section 1: Report parameters
- Section 2: Graphs presenting data about the selected appliances (NetScalers, Load Balancers, Gateways ) over the selected time period
- Section 3: Grid containing additional details about each appliance of the selected type (NetScalers, Load Balancers, Gateways ) that is included in the report
Report Parameters
Section 1 of each report contains controls with which you can select the scope of the report.
Figure 2: Section 1: Parameters section of the Citrix NetScaler Load Balancing report
Select the parameters as follows :
Time frame: On the upper-right, choose the period of time to include in the report.
NetScalers: From the first dropdown list, choose the NetScalers to include in the report. (By default, all are selected.) When you are finished, select OK.
Figure 3: Selected NetScalers in the dropdown listLoad Balancers (Load Balancing report) or Gateways (Gateway report): From the second dropdown list, choose the Load Balancers or Gateways to include in the report. (By default, all are selected.) When you are finished, select OK.
Note
This dropdown list does not exist in the Citrix NetScaler ADC report.
- Mode: From the display-mode dropdown list, choose the display mode for the graphs, as follows:
Figure 4: Display-mode dropdown list
- One-line – summary: Each value shown in a graph represents the values of all the selected NetScalers combined. If the metric is a percentage, each value is the average of the percentages of all the selected appliances. If the metric is any other type of quantity, each value is the sum of the average values of all the selected appliances.
Figure 5: “One line – summary” mode
- One line per appliance: The values in the graphs are plotted separately for each selected NetScaler.

Note
The Mode setting does not affect the grids at the bottom of the report.
Citrix NetScaler ADC Report: Graphs and Grid

NetScaler Configuration History
Changes in NetScaler configuration can cause unexpected problems to arise. Ascertaining when changes were made can help you identify the sources of these issues. The grid in section 3 of the Citrix NetScaler ADC report contains links to information about when NetScaler configuration changes were saved, and when they were implemented, within the timeframe of the report. The list of changes can also be exported to a CSV file, which can be opened by spreadsheet applications like MS Excel and/or saved for future reference.
To see a list of configuration changes that were made on a NetScaler:
- In the Config column, click the Config info link of the NetScaler. The Configuration changes window opens and displays the list.

Troubleshooting
In some cases, a NetScaler report will not open when you select it from the Insights menu. In these cases, error pages are displayed instead.
The most common cause of this problem is that the ControlUp software needs to be upgraded to a version that supports this report (version 7.1 and higher).
