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.

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 versus 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.

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 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.

Create a custom report

1. In the Reporting tool, on the report toolbar, click Create, or if you want to create a 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.

Modifying the time interval

By default, built-in reports display data for the last day. However, if you want to change the time interval for a built-in report, you can save the report as a custom report. The new interval applies to all charts in the report. The following table describes the time-interval options.

Modify the time interval

1. In the left pane of the Reporting tool, click a report.
2. On the report toolbar, click Duration, and then click a time interval.

Setting the data Source and time zone

You can retrieve data from different data sources to display them in the reports. You can also define the time zone for the reports and apply the currently displayed report’s time selection to all the reports, including the built-in reports.

Set the data source and time zone

1. In the Reporting tool, on the report toolbar, click Settings.
2. In the Settings dialog box, in Data Source, select the data source from which you want to retrieve the counter information.
3. Do one or both of the following:
   • If you want the tool to remember the time period for which a chart is plotted, select the Remember time selection for charts check box.
   • If you want the reports to use the time settings of your Citrix ADC appliance, select the Use Appliance’s time zone check box.

Exporting and importing custom reports

You can share reports with other Citrix ADC administrators by exporting reports. You can also import reports.

Export or import custom reports

   When you export the file, it is exported in a .gz file format.

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.

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.

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 counters for global counters, such as Integrated Cache and Compression, click System global statistics.
   • 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 keeps 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.

Stop nscollect

At the command prompt, type:

/netscaler/nscollect stop

Start nscollect on the current SSH session to the Citrix ADC:

At the command prompt, type:

/netscaler/nscollect start

Start nscollect on the local system:

At the command prompt, type:

/netscaler/nscollect start &

Configure flexible monitoring of entities

The Citrix ADC appliance supports storing the required entities in the database. This functionality provides you the flexibility to monitor the selected entities in the reporting tool. You can add or remove the required entities in the database.

Monitor the required entity

Additionally, the reporting process provides you with an option to configure the required entity that you want to monitor. If you select an entity to monitor, the data of other entities of the same type which were monitored earlier will be stopped. However, the entities belonging to a different type continues to be monitored. For example, the reporting process can monitor a maximum of 50 crvservers, 1000 lbvservers, 2500 services, and so on. If you configure 5000 lbvservers on the Citrix ADC appliance, the reporting process only stores the data of the first 1000 lbvservers into the database and ignores the remaining ones. You are provided with an option in reporting for the lbvserver, about which entity to store data into the database and which to ignore. However, the threshold limit remains the same. The new entity is configured with the help of add reportingconfig command. At the command prompt, type:

add reportingconfig <entity> <name> Example: add reportingconfig lbvserver -name lbv1

The above command monitors the lbv1 entity. Rest all the lbvservers if they were monitored earlier will be stopped. However, the threshold value of the lbvserver entity remains the same.

The configured entity that was added using the add reportingconfig command, can be removed with the help of rm reportingconfig <entity> <name>.

At the command prompt, type:

rm reportingconfig <entity> <name> Example: rm reportingconfig lbvserver -name lbv1

The above command removes the lbv1 entity from getting monitored. If this is the last entity that is removed from flexible monitoring, then the monitoring continues in the conventional way.

You can list the entities that are monitored using the flexible reporting feature using the following command.

At the command prompt, type:

show reportingconfig <entity> <name>

Example: show reportingconfig lbvserver

The preceding command lists all the lbservers that are actively monitored.

Note:

The reporting process is refreshed every five minutes.

System level reporting

The reporting process provides you with an option to configure the threshold limit at the system level, instead of individual entity level. With this you can add any required entity that you want to monitor up to the system threshold limit. In the System level reporting, the following conditions must be considered.

• The entities must be configured using add reportingconfig command.
• The entities that were configured in the conventional way stops monitoring. You have to use add reportingconfig command to enable monitoring on the required entities.
• The threshold limit of the entities monitored is at the system level and not at the individual entity level.

Enable the system level reporting.

At the command prompt, type:

enable systemLevelReporting

The preceding command enables the system level reporting. Rest all the entities that were monitored earlier in the conventional way, stops. However, the entities that were added as part of flexible monitoring remains monitored.

Disable the system level reporting.

At the command prompt, type:

disable systemLevelReporting

The preceding command disables the system level reporting.

Show the system level reporting.

At the command prompt, type:

show systemLevelReporting

The preceding command lists the details of the system level reporting.
