Analyzing Data for a Site in Real Time

  • Updated

This article discusses how to use the Real Time screen to analyze date for a site.

Overview of Real Time Analytics for a Site

The Site Monitoring > Real Time screen shows the analytics data for a site in real time. You can show these kinds of network data:

  • Transport - Network data for each transport similar to the Network Analytics window, for example: throughput, packet loss, jitter and so on

  • QoS - Network data similar to the Priority Analyzer window, for example: throughput for each Bandwidth Management profile, and MOS

Showing the Real Time Analytics for a Site

To show the analytics for a site in real time:

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

  2. From the navigation menu, select Site Monitoring > Real Time.

Real Time Transport Analytics

The Transport section focuses on the real time top hosts and apps for the transport links. The top half of the window shows the metrics for each link, and the bottom half shows the data in separate graphs. The following example explains the sections in the Site Real Time Transport screen:

QoS and Transport tabs

Click the relevant tab to show real time QoS or transport data.

General Indicators

  • Capacity - total capacity for all links at the site (upstream, downstream). Capacity is the total bandwidth for the site, minus the Cato system traffic (about 9% of the site bandwidth).

  • Throughput - current total throughput (upstream, downstream).

  • Queue Size - Traffic (upstream, downstream) that is queued by the QoS engine in a buffer due to bandwidth congestion. The packets are stored until the QoS engine is able to send them (or discards them).

  • Discarded - current number of packets (upstream, downstream) discarded by the QoS engine due to congestion.

Timeline graphs of transport traffic

Select one of the views to choose how the data is displayed on the graph. You can also pause the data flow.

4

Transport links

Overview of real time traffic data for each Transport link.

5

Top hosts and applications

List of top hosts and applications with throughput for the link.

Real Time Transport Graphs

The lower half of the Transport section shows connectivity graphs for data related to traffic inside the secure tunnel to the Cato Cloud:

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

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

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

  • Discarded - current number of packets (upstream, downstream) discarded by the QoS engine due to congestion.

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

Real Time QoS Analytics

The QoS section focuses on the real time top hosts and applications for the QoS Bandwidth Management profiles. The following example explains the sections in the Site Real Time QoS window:
