The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This chapter provides information about administering applications for a site and monitoring the sites.
Use the Administer Application Policy menu option to place applications in categories, view and, if required, change the available bandwidth to share bandwidth between applications.
The Categorize Applications window shows application policies and categories to which the applications are assigned. You can use options to change the bandwidth used by applications in the network.
Applications are grouped into categories. To find the category to which an application belongs, enter the application name in the search textbox to the right of the window.
Click a category (for example, backup-and-storage), to see the applications assigned to the category in a drop-down box. The attributes of an application can be edited by clicking the pencil symbol next to the application name in the drop-down box.
You can keep track of application bandwidth usage at each category and move applications between application categories. Categories are grouped into Business Critical, Scavenger and Default groups. The Business Critical group is given the most bandwidth.
Click “Add Application” to provide details of a new application and assign it to a category.
Enter values in the following fields:
To define the application policy groups, click “Define Application Policy.”
Applications are grouped into categories, such as “Voice and Video”. The categories form part of the following business groups: Business Critical, Scavenger and Default.
Click on the down arrow next to a category to change the Application Performance in the category to perform the following:
Select a Path Preference, with Path 1 being the preferred path for traffic in this category. For example, “Int” (Internet).
If you specified metered link as a link type for a service provider, the following dialog appears.
The metered link is the last resort when the primary, secondary, and tertiary paths are not available.
After updating the path preference, click Save.
Note The Save option does not check for validations in conflict with future scheduled workflows. Please reevaluate scheduled jobs based on these changes and update scheduled jobs as required. If there is a conflict when the scheduled job is activated, it may fail at that time.
You can drag-and-drop a category from one business group to another; for example, from Default to Scavenger.
You can view the bandwidth used across various applications in a location by selecting “Bandwidth Usage.” This provides a applications used per location, the bandwidth per Mbps, and the link SLA capacity for each router in a location in pie chart.
In the IWAN Home page, click Monitoring to monitor IWAN sites. The sites are displayed on a map, indicating the number of hubs and branches present across the globe for IWAN.
Clicking on a site displays the following (as links):
Note Troubleshooting is displayed on when the system suspects the site to have an issue due to an application or with bandwidth allocation.
Clicking Application Health displays the applications usage on the site in a graphical representation. The graph displays the following:
As mentioned, Troubleshooting is displayed, when the system detects high usage on a site.
Figure 6-3 Troubleshooting—Detection
In addition to detecting the application causing the issue, the system also provides suggestions to improve the site. For example, if a site uses more bandwidth the system provides suggestion in adjusting the bandwidth among the various applications thereby providing more bandwidth to the application causing the issue.
