Internet Insights is accessible from the link on the left-hand menu of the ThousandEyes platform. The following sections appear under that menu:
Internet Insights > Overview: This dashboard superimposes recent and ongoing outages onto a global map. The most recent outages are listed, along with a geographical distribution of affected interfaces.
Internet Insights > Views: This outage timeline charts outage events in a timeline that can be filtered by network, location, impacted service, and relevance to your tests. A topology depicts service paths, showing source and destination traffic flows; and indicates which ones are being disrupted. The Topology tab shows the location and source of intervening outages.
The Internet Insights > Overview features include:
Map: Internet outages are shown in red, application outages are purple. The size of the node indicates the scope of the outage.
This map reflects your settings in the filters and time range selector described above.
Click a location to see details of the outage.
Once you have clicked a location, you can also click a specific outage to see its detailed visualizations in Internet Insights > Views.
Time Range Selector: For selecting a time range (for example, the last 12 hours). Time ranges are displayed using the time zone configured in the user's profile. By default, Internet Insights displays data for the last 24 hours.
Filter Selectors: Outage Type is either All, Network, or Application. Outage Scope is either All, or only those outages that affect your own tests. Affected Provider lets you choose which provider types to show on the map, for example SaaS (such as 1Password or Adobe) or IAAS (such as Rackspace).
Summary block: Lists the total number of outages, the locations of the displayed outages, the number of affected tests in your account group, and any related alerts.
Outage Events: A list of most outages. Click the blue text to navigate to the Views screen for that network outage. By detecting traces that don't reach their intended target, we can infer that there's something wrong somewhere in the path.
We define outages as events with packet loss above a system-defined baseline, that happen on a particular network at a particular point in time.
This list reflects your settings in the filters and time range selector described above.
You can hover over a listed outage to see it isolated on the map, or click a listed outage's row to zoom the map to that location. (Click again to restore the map to the default zoom level.)
To see an outage's detailed visualizations, click the service name or the outbound-arrow icon.
Pagination Controls: The Network list is paginated to show the 5 most recent outages. You can use the > and < buttons (Next and Previous) buttons to navigate to older outages.
Timeline: A 24-hour timeline of outages overall is expressed in a histogram at the top of the Overview.
Affected Interface Map Nodes: Hover over each map node to view a sublist by location. For navigating to the outage view on the selected network, select a listed outage.
Map Zoom: Use the plus (+) or minus (-) icons to zoom in and out of the map, or use the scrolling feature on your mouse or trackpad. Zooming in on an area shows finer geographic detail between sites of affected interfaces.
How Package Subscriptions Affect the Overview
It’s important to note that the outages you see in Internet Insights on the Overview map will only show your own tests, unless you subscribe to packages as described on Configuring Internet Insights. The packages provide the full benefit of collective intelligence, which you can’t get from individual tests alone. However, you don’t have to subscribe to every package, either – only the ones that matter the most for your needs.
On the Internet Insights > Views screen, the top portion shows a timeline, as shown in the image below.
For the view, choose either Application Outages or Network Outages.
Outage Scope is All, or only those that affect your tests.
The next filter shows either Network or Application, depending on which view is selected. Networks such as Time Warner are shown with names and AS numbers. Applications are shown by type; for example under HR applications you can choose one or more domains for Workday.
Use Add Filters for fine tuning. The Add filters list changes depending on whether you’ve selected Application or Network as the view.
Application Outage additional filters: Outage Scope, Error type, Affected provider, Application, Affected test, Affected hostname or domain, Server prefix, Server network, Server location.
Network Outage additional filters: Outage Scope, Affected provider, Network, Interface location, Interface IP address, Affected test, Affected hostname or domain, Server location, Server prefix, Server network.
The bottom timeline, with slider, shows data for the past year, which you can use to view historical outages. (Most views show data for the past 30 days).
The Internet Insights views have many navigation features in common with other test-specific views. For basic information on using ThousandEyes views, see Getting Started with Views.
The Internet Insights > Views > Topology tab displays different information, depending on whether you have Network Outages or Application Outages selected as the view at the top of the screen.
Network Outages Topology
if you have the Network Outages view selected, you’ll see a path visualization similar to the one shown below.
On the Internet Insights Network Outages view topology, the nodes represent networks or locations, with sources on the left and targets on the right.
By default, sources are displayed as aggregated by country. IP and domain are not displayed. The number of agents is tabulated in the menu that appears when you hover over the source node.
By default, intermediate nodes are aggregated by Autonomous System Number (ASN).
The menu that appears when you hover over the node shows the number of affected destinations and provides a link that shows the list of affected tests in a pop-up window.
Affected ASes are determined from public rDNS on the target IP and not target domain.
By default, only links with 0% of traces and affected servers 10% are shown.
Targets show the ASN and the number of affected interfaces in the view. The menu that appears when you hover over the node will show the number of affected destinations and provide a link that will show the list of affected tests in a pop-up window. Another link is available that shows only outages affecting the destinations relevant to that node.
Click Next nodes (if available) to see more nodes impacted by an outage event.
Click on a node to show a focused path visualization for just that node, and use the < Undo button to restore the full path visualization.
The Topology tab includes Showing (filtering) and Grouping options to highlight aspects of the topology visualization, as shown below.
Nodes with outages are tallied under Highlighting. You can narrow the highlighting using the field Highlight nodes that match all / any and then choosing a list item such as Test name, Location, IP address, Prefix, or Domain. For example, if you choose Domain, a list of affected domains appears, and you can select one of those to highlight only those affected nodes on the path visualization.
When you've selected a timeslice in the timeline, the Internet Insights > Views > Map tab shows a map of the outage(s) along with summarized outage information.
When you've selected a timeslice in the timeline, the Internet Insights > Views > Table tab shows information about the outage(s) in table form. Click a network name to open details about the outage.
Catalog Settings Screen
To see Catalog Settings, go to Internet Insights > Catalog Settings. This section lists service providers, grouped by region. The catalog exposes provider data that is already public-facing. Private IPs are not exposed and are de-identified and aggregated.
