title: Customizing Help Text for Efficiency Analytics
---

This document describes how to customize the help text displayed when viewing the analytics in the Efficiency Tab and remove any analytics that are not pertinent to your center.
These instructions are intended for a system administrator of an Open XDMoD instance. Information about the use of the efficiency tab can be found in the user manual which is available from the "Help" menu on the top right of the XDMoD portal.
## Efficiency Analytics

The efficiency analytics are shown when you first navigate to the efficiency tab. With each analytic,
there is associated text explaining what the analytic is, what is considered inefficient in regard to the analytic, and
supporting text giving suggestions of how to improve efficiency regarding a specific analytic.

As of the 10.0 release, there are six analytics. These are CPU Usage, GPU Usage, Memory Usage, Homogeneity, Wall Time Accuracy, and Short Jobs. When you first navigate to the efficiency tab, you will see cards each representing an analytic. Each card includes a brief description of the analytic as well as a scatter plot that allows you to visualize how users rank in each analytic (see Figure 1 below).

The view shows six cards broken down into two categories - one for usage analytics which includes CPU Usage, GPU Usage, Memory Usage and Homogeneity and one for design analytics which includes Wall Time Accuracy and Short Jobs. Each card displays a short description of the analytic and a thumbnail view of the scatter plot related to that analytic. The scatter plot points represent a user's usage on the resource and efficiency of their jobs for the specific analytic." />

</figure>

Upon clicking on one of the analytic cards, a user will be shown a larger view of the scatter plot that they can interact with by filtering or drilling down. In this view, more text is presented to give more information about the specific analytic and how efficiency may be improved for that analytic. Figure 2 below shows this view for CPU Usage. In this image, you can see the help text at the top of the image above the scatter plot. The associated help text shown in this view can be customized as needed for different centers.

Each analytic from the initial efficiency tab page can be viewed in more detail by clicking on the analytic card. This view shows the same scatter plot from the analytic card, but the scatter plot can be filtered or drilled down to learn more information about the users and their respective jobs represented by the scatter plot points. In addition to the scatter plot, there is a side bar that allows filtering and above the scatter plot is the help text explaining the analytic in more detail and giving more information on how to improve efficiency in regard to this analytic." />

You may want to customize this text to provide more focused feedback for users at your center or provide links to help text as appropriate. To do so, please follow the directions provided below.

**These instructions only apply to Open XDMoD 10.0. For later versions please refer to the documentation for that release.**

To customize text for an analytic you need to edit the `/etc/xdmod/efficiency_analytics.json` configuration file. For example, to edit the help text for the CPU Usage scatter plot you would edit the html that is under "documentation" in lines 28-37. To edit the help text for the CPU Usage histogram, you would edit the html that is under "histogramHelpText" in lines 46-55. The lines to edit for each are shown below.
```json
28 "documentation": [
39 "<div class='text'>",
30 "<h6> What is this analytic? </h6>",
31 "<p>The chart below shows the percentage of time that the CPU cores were idle compared to overall usage. Each point on the plot shows the data for the jobs for a particular user.</p>",
32 "<h6> Why is this analytic important? </h6>",
33 "<p>Making sure jobs use the right number of CPU cores helps ensure that the compute resources are used efficiently.</p>",
34 "<h6> How do I improve future jobs? </h6>",
35 "<p>For typical compute intensive jobs, the overall CPU usage should be &gt; 90 % (i.e. CPU core idle &lt; 10 %). Consider requesting fewer CPU cores for future jobs, or adjust the configuration settings of the software to make use of all the cores that have been requested.</p>",
36 "</div>"
37 ],
```

```json
46 "histogramHelpText": [
47 "<div class='text'>",
48 "<h6> What is this analytic? </h6>",
49 "<p>The chart below shows the percentage of time that the CPU cores were idle compared to overall usage.</p>",
50 "<h6> Why is this analytic important? </h6>",
51 "<p>Making sure jobs use the right number of CPU cores helps ensure that the compute resources are used efficiently.</p>",
52 "<h6> How do I improve future jobs? </h6>",
53 "<p>For typical compute intensive jobs, the overall CPU usage should be &gt; 90 % (i.e. CPU core idle &lt; 10 %). Consider requesting fewer CPU cores for future jobs, or adjust the configuration settings of the software to make use of all the cores that have been requested.</p>",
54 "</div>"
55 ]
```

For editing help text for other analytics, the process is the same, but you need to change the "documentation" that corresponds to that specific analytic. Not all analytics include alternative help text for the histogram view. If you want to include this text, add in the histogramHelpText section under the histogram json for the analytic that you are interested in changing. If you want to exclude this text, remove the histogramHelpText section from the histogram json for that specific analytic.

In addition to editing the help text, you can also remove an analytic if it is not pertinent to your center. To do this, you need to remove the analytic from the `/etc/xdmod/efficiency_analytics.json` configuration file. For example, to remove GPU Usage from showing in the XDMoD interface, you would remove lines 58-109 from this file. The lines to remove are shown below.

**As of Open XDMoD 11.0, the histogram configuration setting `rotate` is deprecated. Please update any custom analytic configurations you may have.**

106 "</div>"
107 ]
108 }
109 },
```

Figure 3 below shows an example of what the updated efficiency tab interface would look like if you were to remove GPU Usage.
