Reporting tool 编辑

Use the Citrix® Citrix ADC® Reporting tool to view Citrix ADC performance statistics data as reports. Statistics data are collected by the nscollect utility and are stored in a database. When you want to view certain performance data over a period, the Reporting tool pulls out specified data from the database and displays them in charts.

Reports are a collection of charts. The Reporting tool provides built-in reports and the option to create custom reports. In a report, you can modify the charts and add new charts. You can also modify the operation of the data collection utility, nscollect, and stop or start its operation.

Using the reporting tool

The Reporting tool is a web-based interface accessed from the Citrix® Citrix ADC® appliance. Use the Reporting tool to display the performance statistics data as reports containing graphs. In addition to using the built-in reports, you can create custom reports, which you can modify at any time. Reports can have between one and four charts. You can create up to 256 custom reports. You can create a custom report for any number of entities.

To invoke the reporting tool

1. Use the Web browser of your choice to connect to the IP address of the Citrix ADC (for example, http://10.102.29.170/). The Web Logon screen appears.
2. In the User Name text box, type the user name assigned to the Citrix ADC.
3. In the Password text box, type the password.
4. In the Start in drop-down list box, select Reporting.Click Login.

The following screenshots show the report toolbar and the chart toolbar, which are frequently referenced in this documentation.

Working with reports

You can plot and monitor statistics for the various functional groups configured on the Citrix ADC over a specified time interval. Reports enable you to troubleshoot or analyze the behavior of your appliance. There are two types of reports: built-in reports and custom reports. Report content for built-in or custom reports can be viewed in a graphical format or a tabular format. The graphical view consists of line, area, and bar charts that can display up to 32 sets of data (counters). The tabular view displays the data in columns and rows. This view is useful for debugging error counters.

The default report that is displayed in the Reporting tool is CPU vs. Memory Usage and HTTP Requests Rate. You can change the default report view by displaying the report you want as your default view, and then clicking Default Report.

Reports can be generated for the last hour, last day, last week, last month, last year, or you can customize the duration.

You can do the following with reports:

• Toggle between a tabular view of data and a graphical view of data.
• Change the graphical display type, such as bar chart or line chart.
• Customize charts in a report.
• Export the chart as an Excel comma-separated value (CSV) file.
• View the charts in detail by zooming in, zooming out, or using a drag operation (scrolling).
• Set a report as the default report for viewing whenever you log on.
• Add or remove counters.
• Print reports.
• Refresh reports to view the latest performance data.

Using built-in reports

The Reporting tool provides built-in reports for frequently viewed data. Built-in reports are available for the following functional groups: System, Network, SSL, Compression, Integrated Cache, Citrix ADC Gateway, and Citrix ADC Application Firewall. By default, the built-in reports are displayed for the last day. However, you can view the reports for the last hour, last week, last month, or last year.

Note:

You cannot save changes to built-in reports, but you can save a modified built-in report as a custom report.

To display a built-in report

1. In the left pane of the Reporting tool, under Built-in Reports, expand a group (for example, SSL).
2. Click a report (for example, SSL > All Backend Ciphers).

Creating and deleting reports

You can create your own custom reports and save them with user-defined names for reuse. You can plot different counters for different groups based on your requirements. You can create up to 256 custom reports.

You can either create a new report or save a built-in report as a custom report. By default, a newly created custom report contains one chart named System Overview, which displays the CPU Usage counter plotted for the last day. You can customize the interval and set the data source and time zone from the report toolbar.

To create a custom report

1. In the Reporting tool, on the report toolbar, click Create, or if you want to create a new custom report based on an existing report, open the existing report, and then click Save As.
2. In Report Name box, type a name for the custom report.
3. Do one of the following:
   • To add the report to an existing folder, in Create in or Save in, click the down arrow to choose an existing folder, and then click OK.
   • To create a new folder to store the report, click the Click to add folder icon, in Folder Name, type the name of the folder, and in Create in, specify where you want the new folder to reside in the hierarchy, and then click OK.

Note: You can create up to 128 folders.

To delete a custom report

Working with charts

Use charts to plot and monitor counters or groups of counters. You can include up to four charts in one report. In each chart, you can plot up to 32 counters. The charts can use different graphical formats (for example, area and bar). You can move the charts up or down within the report, customize the colors and visual display for each counter in a chart, and delete a chart when you do not want to monitor it.

In all report charts, the horizontal axis represents time and the vertical axis represents the value of the counter.

Adding a chart

When you add a chart to a report, the System Overview chart appears with the CPU Usage counter plotted for the last one day.

Note:

If you add charts to a built-in report, and you want to retain the report, you must save the report as a custom report.

Use the following procedure to add a chart to a report.

To add a chart to a report

1. In the left pane of the Reporting tool, click a report.
2. Under the chart where you want to add the new chart, click the Add icon.

Modifying a chart

You can modify a chart by changing the functional group for which the statistics are displayed and by selecting different counters.

To modify a chart

1. In the left pane of the Reporting tool, click a report.
2. Under the chart that you want to modify, click Counters.
3. In the dialog box that appears, in the Title box, type a name for the chart.
4. Next to the Plot chart for, do one of the following:

   • To plot entity counters for entity types, such as Load Balancing and GSLB, click System entities statistics.
5. In the Select group, click the desired entity.
6. Under Counters, in Available, click one or more counter names that you want to plot, and then click the > button.
7. If you selected System entities statistics in step 4, on the Entities tab, under Available, click one or more entity instance names you want to plot, and then click the > button.
8. Click OK.

Viewing a chart

You can specify the graphical formats of the plotted counters in a chart. Charts can be viewed as line charts, spline charts, step-line charts, scatter charts, area charts, bar charts, stacked area charts, and stacked bar charts. You can also zoom in, zoom out, or scroll inside the plot area of a chart. You can zoom in or out for all data sources for 1 hour, 1 day, 1 week, 1 month, 1 year, and 3 years.

Other options for customizing the view of a chart include customizing the axes of the charts, changing the background and edge color of the plot area, customizing the color and size of the grids, and customizing the display of each data set (counter) in a chart.

Data set numbers, such as Data Set 1, correspond to the order in which the counters in your graph are displayed at the bottom of the chart. For example, if CPU usage and Memory usage are displayed in first and second order at the bottom of the chart, CPU usage is equal to Data Set 1 and Memory usage is equal to Data Set 2.

Whenever you modify a built-in report, you need to save the report as a custom report to retain your changes.

Stopping and starting the data collection utility

The data collection utility, nscollect, runs automatically when you start the Citrix ADC. This utility retrieves the application performance data and stores it in the form of data sources on the ADC. You can create up to 32 data sources. The default data source is /var/log/db/default.

The data collection utility creates databases for global counters and entity-specific counters, and uses this data to generate reports. Global-counter databases are created at /var/log/db/<DataSourceName>. The entity-specific databases are created based on the entities configured on the Citrix ADC, and a separate folder is created for each entity type in /var/log/db/<DataSourceName/EntityNameDB>.

The nscollect retrieves data once every 5 minutes. It retains data in 5-minute granularity for one day, hourly for the last 30 days, and daily for three years.

You might have to stop and restart the data collection utility if data is not updated accurately or the reports display corrupted data.

To stop nscollect

At the command prompt, type:

/netscaler/nscollect stop

To start nscollect on the current SSH session to the Citrix ADC:

At the command prompt, type:

/netscaler/nscollect start

To start nscollect on the local system:

At the command prompt, type:

/netscaler/nscollect start &
