Showing the Site Network Analytics

The Network Analytics page helps you analyze the state and quality of the connections of a site to the Cato Cloud. The data in this page shows information for the site and tunnel, port utilization, and LTE statistics.

Note

Notes:

  • Cato calculates the link connectivity data every millisecond, however the minimum bucket size in the Network Analytics page is 5 seconds. It is possible that packets are discarded, even though the analytics in this page don't show 100% usage.

  • The Network Analytics page is typically up-to-date within a 5 minutes time frame. However, it is possible that some data will be delayed up to 30 minutes.

  • Port utilization and LTE data is available only for Socket sites, and only from v20 and higher.

Using the Overview Section

To show the network analytics for a site:

  1. From the navigation menu, click Network > Sites and select the site.

  2. From the navigation menu, click Site Monitoring > Network Analytics

This example and the table that follows explain the fields in the Overview section:

Metrics_Overview_Callouts.png

Item

Name

Description

1

Network Analytics site

Select the site that is showing network analytics data

2

Network Analytics fields for the site

See below, Explanation of the Network Analytics for a Site

3

Devices

Select which device analytics to display. See below, Explanation of the Network Analytics for a Site

4

Site & Tunnel and Socket Utilization tabs

Select to show the graphic Overview of the links, or the Socket Utilization tabs.

For Socket X1600 LTE models, an additional LTE tab is available.

5

Bucket Granularity

Amount of time for a specific data point. In the example above, each data point represents 10 minutes of aggregated traffic

6

Pin for Overview and Details tabs

The Overview and Details tabs are unpinned by default, when they are pinned, then these tabs are still shown when you scroll down

7

Link connection status

Data of an individual link for the site

  • The green bar shows the active link

  • The light green bar shows the passive link with connectivity to the Cato Cloud

  • A gray bar indicates that the link is down

  • A yellow section within the bar indicates 2% or more packet loss in either upstream or downstream

8

Aggregated connection status

Aggregated data of the links for the site

The aggregated bar shows the status of the link with the best health for that bucket granularity. For example, if the link for ISP A had a green status and the link for ISP B had an yellow status, the aggregated bar shows a green status.

Note

Note: The ISP data in this window is provided by ip2location.com

Explanation of the Network Analytics for a Site

  • Status - the site is Connected or Disconnected to the Cato Cloud

  • HA Status - for sites with Socket high availability (HA), status of the HA configuration (otherwise, shows N/A if the site)

  • Master - indicates whether the Primary or Secondary Socket is actively sending/receiving traffic

  • Socket or IPsec- Socket type or IPsec connection

  • PoP - PoP the site is connected to

  • Distance - round trip time between the site and the Cato Cloud

  • #Hosts - number of hosts in the LAN for this site

  • Devices - select the Socket data that is displayed in the Network Analytics window:

    • Merged - combines data for the primary and secondary Socket

    • Primary - only shows data for the primary Socket

    • Secondary - only shows data for the secondary Socket

Chinese PoP Locations

For PoP locations in China, some locations have multiple PoPs that a site can connect to. For example, Shanghai_DC1 and Shanghai_DC3.

Using the Connectivity Graphs

The following graphs display data related to traffic inside the secure tunnel to the Cato Cloud:

  • Avg Throughput - average upstream and downstream throughput for each link (over the length of the bucket)

  • Max Throughput - maximum upstream and downstream throughput, and average throughput for each link (over the length of the bucket)

  • Packet Loss - packet loss percentage over the last mile inside the tunnel

  • Distance - round trip time between the site and the Cato Cloud inside the tunnel

  • Tunnel Age - total time that the current DTLS tunnel between the Socket and the PoP is connected

  • Jitter - difference in time delay in milliseconds (ms) between data packets

  • Flows - flow counts during the specified period of time

  • Hosts - host count during the specified period of time

This is an example of the Throughput graphs:

Metrics_Throughput.png

These graphs show analytics that are related to the last mile connection (outside of the secure tunnel) between the Socket site and the Cato Cloud. The goal of this data is to show you the quality of the ISP link to the Cato Cloud:

  • Last Mile Packet Loss - packet loss percentage over the last mile outside the tunnel

  • Last Mile Distance - round trip time (RTT) between the site and the Cato Cloud outside the tunnel

Using the Socket Utilization Graphs

The following graphs display the data related to the Socket's physical port utilization for its interfaces (LAN1, LAN2, WAN1, etc.):

Socket_Utilization.png
  • Total Bytes by Transport - the total amount of data sent (Tx) and data received (Rx) for all transport types over your different interfaces. This gives you insight into how much traffic you're sending to the cloud, how much over the internet, and more. You can filter the information to only see a specific interface, or interfaces, using the drop-down menu.

  • Avg. Throughput by Transport - the amount of data sent and received per transport type over time. You can filter to only see a specific interface, and select the checkboxes for the transport types to display.

  • Avg. Throughput by Port - the amount of data sent and received for per interface. You can filter to only see a specific transport type, and select the checkboxes for the interfaces to display.

Note

Note: The data in the graphs is from the perspective of the Socket. Meaning, if someone in the LAN downloads a file, the Socket will show it as received (Rx) from the Cato Cloud or internet, and transferred (Tx) to the user.

Using the LTE Graphs

The following graphs display data related to traffic from the LTE connection, and are available under the LTE tab of the Site Analytics page:

Note

This tab is available only for X1600 LTE Sockets.

  • Cellular Interface Data Usage - the amount of data send and received over the LTE connection. You can also filter for specific transport types in the Show Transports drop-down menu.

  • Avg. Signal Strenth - the quality of the cellular connection over time.

  • Avg. RSRQ - the quality of the received reference signal over time. Is used together with Avg. RSRP to determine the overall quality of the connection.

  • Avg. RSRP - the strength of the received reference signal. Is used together with Avg. RSRQ to determine the overall quality of the connection.

  • Avg. RSSI - the quality of the signal your device receives from an access point or router.

  • Avg. SINR - the ratio of signal strength to noise over the cellular line.

Comparing App Analytics and Network Analytics

The analytics and metrics for the App Analytics page and the pages for network analytics (such as Monitoring > Sites Overview) can have a small discrepancy because the data is calculated differently.

  • For network analytics data (including the account Metrics API query):

    • Upstream and downstream bytes are counted for encapsulated packets (including DTLS headers overhead)

    • Upstream and downstream data for all flows related to the given tunnel are aggregated together

  • For the App Analytics data:

    • Upstream and downstream bytes are counted for non-encapsulated packets (before DTLS encapsulation).

    • Upstream and downstream data is displayed per application

    Document needs updating, “Socket Utilization” tab doesnt exist.

    Hi Sasika, thank you for writing in. 

    I'm seeing the Socket Utilization tab for my X1500 Socket right now - can you please let me know what you are seeing?

    Hi Yaron 

    Thanks for replying!

    Under Network Analytics, there aren't 2 tabs on our X1500 (Ver: 19.0.17557).

    The page starts off with the Links overview and then continues with the Max Throughput and Avg. Throughput graphs.

    Hi Sasika - I understand now. 

    The new tabs are available only as of Socket v20. I will try and make that note at the top of this KB clearer to avoid future confusion.
