Load Evaluator Index Analytics Report
A server’s load index may be the aggregate of:
The Citrix Delivery Controller computes the load evaluator index for each XenApp server it manages and uses this index to determine how suitable a Citrix XenApp worker is to receive a new user session. It is the Citrix Delivery Controller’s responsibility to calculate the load index based on the aggregate of the normalized load rule indexes generated by the various load rules. As only the Delivery Controller can determine the session load, a server’s overall load index is calculated on the Delivery Controller. Citrix administrators need to periodically evaluate the load on the servers managed by a Citrix Delivery group. Also, they need a historical analysis of the load on the servers to ensure that the load is uniformly balanced across all the servers. Using the Load Evaluator Index Analytics report, administrators not only obtain the historical analysis of the load but are also pointed to the server that is overloaded and the exact resource that is a constraint.
To generate this report, do the following:
Figure 1 then appears. In Figure 1, select a criteria for analysis from the Analyze By list box.
Figure 1 : Specifying the criteria for generating the Load Evaluator Index Analytics report
By default, this report can be generated for one/more managed components, or those that are part of a zone, service or segment. The options provided by the Analysis By list box are discussed hereunder:
Then, specify the Timeline for generating this report. You can either provide a fixed time line such as 1 hour, 2 days, etc., or select the Any option from the list to provide a From and To date/time for report generation.
Note:
For every user registered with the eG Enterprise system, the administrator can indicate the maximum timeline for which that user can generate a report. Once the maximum timeline is set for a user, then, whenever that user logs into eG Reporter and attempts to generate a report, the Timeline list box in the report page will display options according to the maximum timeline setting of that user. For instance, if a user can generate a report for a maximum period of 3 days only, then 3 days will be the highest option displayed in the Timeline list - i.e., 3 days will be the last option in the fixed Timeline list. Similarly, if the user chooses the Any option from the Timeline list and proceeds to provide a start date and end date for report generation using the From and To specifications, eG Enterprise will first check if the user's Timeline specification conforms to his/her maximum timeline setting. If not, report generation will fail. For instance, for a user who is allowed to generate reports spanning over a maximum period of 3 days only, the difference between the From and To dates should never be over 3 days. If it is, then, upon clicking the Run Report button a message box will appear, prompting the user to change the From and To specification.
In addition to the settings discussed above, this report comes with a set of default specifications. These settings are hidden by default. If you do not want to disturb these default settings, then you can proceed to generate the report by clicking the Run Report button soon after you pick one/more components for report generation. However, if you want to view and then alter these settings (if required), click on the icon. The default settings will then appear in the MORE OPTIONS drop down window (See Figure 2). The steps below discuss each of these settings and how they can be customized.
If the timeline specified for the report needs to exclude the data collected during the Weekends, then set Exclude weekends to Yes. If not, select No.
Note:
By default, the weekend constitutes Saturday and Sunday. To override this default setting, do the following:
Next, indicate the report Time period.
Note:
By default, the Time period is set to 24 hours. Accordingly, the From and To parameters in the [timeframe] section of the eg_report.ini file (in the <eg_install_dir>\manager\config directory) are set to 00:00 and 24:00 respectively. If need be, you can override this default setting by configuring a different timeframe against the From and/or To parameters.
In large environments, reports generated using months of data can take a long time to complete. Administrators now have the option of generating reports on-line or in the background. When a report is scheduled for background generation, administrators can proceed with their other monitoring, diagnosis, and reporting tasks, while the eG manager is processing the report. This saves the administrator valuable time. To schedule background processing of a report, you can either select the Background Save - PDF option from the Report Generation list. To process reports in the foreground, select the Foreground Generation - HTML option from this list.
Note:
If the Report type is Foreground Generation - HTML, then will appear as soon as you click the Run Report button.
