Monitoring bond performance

Performance statistics are recorded for each bond and shown in charts on the bond details page in the Performance section. The charts show historical trends and patterns over a specified period and can provide valuable insight when troubleshooting.

By default, measurements are taken every 10 seconds and reported every 60 seconds.

Use the timeframe selection buttons to choose between displaying one year, one month, one week, one day, six hours, one hour, or 15 minutes. The left (<) and right (>) buttons will shift the current view, while the forward (>>) button takes you to the latest time. When you are at the latest time already, the forward and shift right buttons are disabled.

You can hover your mouse over chart lines to view precise values and timestamps. All times are displayed in your local time zone.

As an example, the following chart shows the throughput of a bond, broken down by the throughput of each leg. Values below the x-axis represent download, while values above the x-axis represent upload.

To view individual legs in more detail, you can uncheck the legs you don’t want to view.

The following charts are shown:

1. Tunnel data traffic: the amount of inbound and outbound traffic on the tunnel.

2. Tunnel latency: the time taken for a ping reply to arrive over the tunnel. The thick line is the average, while the thin line is the standard deviation of the measurements.

3. Leg data traffic: the amount of inbound and outbound traffic on each link.

4. Leg latency: the time taken for a ping reply to arrive, as measured by the tunnel process. The thick line is the average for a leg, while the thin line is the standard deviation of the measurements.

5. Leg packet loss: the amount of packet loss on each leg.

6. Leg state changes: the rate of state changes for each leg.

7. CPU usage (average): the percent of CPU used by type (averaged across all cores), such as user vs system traffic.

8. CPU usage (per core): the percent of CPU used by core, such as CPU 1 vs CPU 2.
