Path Insight (Add-on)

Description

(This feature is available only to SaaS-based Netreo deployments. It is not available for on-premise deployments of Netreo.)

The Path Insight add-on provides highly detailed information about network traffic paths between selected Netreo remote agents and configured destinations, providing complete end-to-end network path visibility.

Details

Selected Netreo remote agents send bursts of test traffic at 15-minute intervals to your configured destination. Netreo records data from the network hops and, by combining various TraceRoute methodologies with built-in Netreo features, builds a complete map of the paths taken by the test traffic. This is then represented visually on the Path Insight dashboard along with a variety of other data including latency and packet loss.

Destinations may be created for anything with a reachable IP address.

The data for each burst of test traffic is stored for 7 days.

Path Insight Administration

To navigate to the Path Insight Administration page go to the main menu and select Administration > Modules > Path Insight.

The Path Insight Administration page is where users with the SuperAdmin access level may create and edit destinations and manage which remote agents will send test traffic to them.

See How to Configure Path Insight.

The Path Insight Dashboard

To navigate to the Path Insight Dashboard go to the main menu and select Quick Views > Path Insight.

The Path Insight dashboard displays information about the network path between a remote agent (source) and a destination.

This dashboard is available to users of all access levels. It consists of the Packet Loss and Latency graph and the Path Insight Map, which are both detailed below.

To View Network Path Data Using Path Insight:

1. Log in to Netreo as a user with any access level.
2. Go to the main menu and select Quick Views > Path Insight to navigate to the Path Insight dashboard.
3. In the MONITORING DESTINATION field select a path destination from the pull-down menu.
4. In the MONITORING AGENT field select an agent(path source) from the pull-down menu to display the Packet Loss and Latency graph for that agent/destination combination.
   • Average packet loss and latency data is shown for the most recent 24-hour period.
   • Hover the mouse cursor over a timestamp in the graph to view detailed data about that set of test traffic. See Packet Loss and Latency Graph below for more details.
   • Use the arrows to page back and forth through the graph by 24-hour increments.
5. Select a timestamp on the Packet Loss and Latency graph to display the Path Insight Map for that timestamp.
   • Hover the mouse cursor over a node or link in the map to view detailed data about that path element. See Path Insight Map below for more details.

Packet Loss and Latency Graph

The Packet Loss and Latency graph shows average packet loss and latency data for the most recent 24-hour period. Destinations are tested every 15 minutes.

Each blue bar represents the average latency for that timestamp (right-side scale), while the red line plots the average packet loss (left-side scale). (If average packet loss is consistently 0% the red line may not be noticeable as it remains at the bottom of the graph.)

Hover the mouse cursor over any point on the graph to see:

• Timestamp
• Average latency for past 24 hours
• Minimum Latency
• Maximum latency
• Packet loss

Use the arrows to page back and forth through the graph by 24-hour increments.

Selecting a point on the graph displays the Path Insight Map for that timestamp below the graph.

Path Insight Map

The Path Insight Map shows the network path taken by the test traffic for the timestamp selected in the Packet Loss and Latency graph. (The selected timestamp is indicated at the top of the map.)

If the network path is very large and/or complex, the map may be panned by clicking and dragging on the map and zoomed in/out using the mouse scroll wheel. Select Reset to re-center and zoom the map.

The map consists of nodes connected by links. Hover the mouse cursor over a node or link in the path to view detailed data about that element.

The data available includes the following:

For nodes

• Hostname or IP address
• Node type
  • External = reachable from outside the network
  • Private = not reachable from outside the network
  • Managed = a managed device (typically also Private)
  • Unreachable = node has timed out
  • Unknown = node cannot be identified as one of the other node types
• Device availability status (if a managed device)

For links

• Link type
  • Inbound = from external node to internal node
  • Outbound = from internal node to external node
  • Internal = from internal node to internal node
  • External = from external node to external node
• Minimum latency
• Maximum latency
• Average latency for past 24 hours
• Packet loss (%)
• Likelihood (%) - How likely traffic is to take this path.
