Using the Experience Monitoring Page

This article explains how to use the Experience Monitoring page to monitor performance and user experience in your network.

Overview of Experience Monitoring

Traffic and performance of applications can be related to factors outside of the Cato Cloud. Experience monitoring provides insight into user experience, proactively monitoring performance and pinpointing issues. From the Experience Monitoring page, you can view a summary of user's experience for application usage across your network. You can use the filters and widgets to help you drill down into the data to troubleshoot the cause of poor performance.

The Experience Monitoring page displays data from traffic that flows through the Cato Cloud. Traffic that is not from either a site or Client is not displayed. For more information about Experience Monitoring, see What is Cato Experience Monitoring.

Known Limitations

  • Application performance metrics are only calculated for TCP traffic. We will support metrics for additional protocols in the future.

  • Sometimes, there are multiple records for a user, such as connecting remotely as opposed to when they are behind a site.

Getting Started with Experience Monitoring

The Experience Monitoring page displays the average score for all applications and a break down of performance per Application, Site, and User or Host.

Note

Note: The Account Experience score is metric is calculated from January, 23rd 2024. All other application performance metrics are collected from December, 2023.

To view the Experience Monitoring page:

  • From the navigation menu, click Monitoring > Experience Monitoring.

    The following table explains the data and analytics available from the Experience Monitoring page.

Name

Description

Filter Bar

The filters are applied to the page. Selected filters apply to all widgets on the page.

A filter for cloud applications is applied by default.

Time Range

The time range applied to the page. The maximum time range is three months.

Account Experience

The average experience score for all applications and the number of applications in each experience category (Good/Fair/Poor).

This is score is based on these application performance metrics:

  • Time to First byte

  • TCP Connect

  • TLS Connect

  • HTTP Latency

  • HTTP/S error

Every application has different learnt thresholds by Cato AI.

Top Applications

The most used applications in your network. By default, this table is sorted by the Experience category. You can sort the table by any of the columns.

Experience Type Tabs

Each tab shows the analytics and data for that entity in your network: Sites, Users/Hosts, and Applications.

Experience Data

Each tab displays data for the selected entity. You can click on items in this table to view more data.

Filtering the Experience Monitoring Page

There are two ways to filter the data in the Experience Monitoring page:

  1. Automatically update the filter with the selected item

  2. Manually configure the filter

Automatically Filtering for an Item

As you hover over an item or field where a filter option is available, the menu icon appears (Menu.png). Click the icon to either add or exclude the item to the filter. The Experience Monitoring page now only shows data that includes the filtered item. For example, if you filter for the Microsoft Word application, the page only shows analytics and data that are related to using the Microsoft Word application. No other application data is displayed until you change or clear the filter.

You can add multiple items to the filter.

Manually Configuring the Filter

You can manually configure the event filter for greater granularity to analyze the events. After you configure the filter, it is added to the events filter bar and the screen is automatically updated to show the events that match the new filter.

You can filter by any of these values:

  • Application

  • Category

  • Country Code

  • PoP

  • Site Name

  • Experience

  • Sanctioned Application

  • Connection Type

  • User/Host

Filter.png

To create a filter:

  1. In the filter bar, click add.png.

  2. Start typing or select the Field.

  3. Select the Operator, which determines the relationship between the Field and the Value you are searching for.

  4. Select the Value.

  5. Click Add Filter.

    The filter is added to the filter bar and the Experience Monitoring page is updated to show results based on the filters.

Clearing the Filter

You can remove each item in the filter separately, or clear the entire filter.

To clear the filters:

  1. To clear a single filter, click the X (remove.png) next to the filter.

  2. To clear all the filters, click the X (remove_icon.png) at the right end of the filter bar.

Reviewing Analytics for Site, Users/Hosts, or Applications

You can review detailed analytics for each site, user/host, or application used in your network. This provides you with granular data to monitor the experience across your network.

To drill down into item, from the experience data, click on an item. A new page opens, click back to return to the Experience Monitoring page.

A User is a remote user connecting with the Client not from a site. A Host is a remote user or a host at a site, for example an IoT device or printer.
