5. Extended Traffic Lights functions

Jisc staff have access to a number of extended features in the Netsight3 Traffic Light pages.

5.1. Access to Ping and Traffic graphs

A graphing dashboard is available for each Reporting Path / circuit, and includes graphs for the current ping and traffic data. This can be accessed by clicking on the Graphs button on the relevant Traffic Light card.

N.B. Data for the Current graphing dashboard is derived from the new Netsight3 pollers. These have only been running for a few months so do not have data going back beyond the start of 2019.

(Access is provided to older, historic traffic data via a separate Historic dashboard which pulls older data from a separate data source. These dashboards can be access from the relevant Traffic measurement job.)

The top graph on the dashboard show 'Traffic In' (in red) and 'Traffic Out' (in blue) for the connection in megabits per second. Traffic data is gathered via SNMP one every five minutes. Note that traffic data is gathered at the Jisc Janet end of each connection. This means that 'Traffic In' equals traffic flow out from the customer organisation back into the network core. 'Traffic Out' is the flow from the Janet core out to customer organisations.

N.B. Please note that the red 'Traffic In' line is shown on a negative Y axis. This is for clarity in the graph display but gives negative values when mousing over the details of the graph. If you want to view the traffic data in and out both on a positive Y axis (where they overlap), you can do this by clicking on the Current button on the relevant measurement job card.

The bottom graph shows average (blue) and minimum (red) Ping round-trip time for the connection in milliseconds. Ping polling is done every minute and ten pings are sent to produce these averages.

5.2. View packet loss history

You are able to see the packet loss history (up to the last 30 events recorded where packet loss was above 0%). You can access this by clicking on the small clock icon in the bottom right hand corner of each reporting path card.

This shows up to the last 30 outage records (if there have been 30 or more).

Note that if the circuit is currently experiencing an outage, you will only see records for the past 30 minutes, as the system will be recording one outage event each minute.

Note that the Ping graph dashboard includes a graph for packet loss which will provide more detail about outages on that circuit.

5.3. Access to Reporting Path and Measurement Job details and graphing

Jisc users can click through from Traffic Light cards and see the full Reporting Path details:
