Testing Network Connectivity

The Network Connectivity test can be used to locate network issues and bottlenecks. The tool sends test data to all Agents connected to the Coordinator, which in turn sends back the same data. Network performance for each Agent is recorded, with the test repeated four times to rule out random results.

The Network Connectivity test can be started from one of the following locations:

  • The Agent Settings dialog box -> Network->General page.
  • The Coordinator Monitor menu.
  • The Start menu -> IncrediBuild option.

Once the test is completed, the test results are displayed:

The following columns are shown for each Agent tested:

ColumnDescription
IconGreen indicates that the connection was successful.
Agent NameThe network name of the machine running the Agent.
StatusThe Agent's current availability and its network adapter speed.
PerformanceAn assessment of the Agent's overall network performance. The percentage indicates how much of the network connection's potential was utilized in the test.
Receive PerformanceSpeed recorded while the Agent received data.
Send PerformanceSpeed recorded while the Agent sent data.
Round-Trip TimeAverage time taken for the whole test round-trip (send+receive). The results of all four tests are also shown.
IP AddressThe machine's IP address and port.
Remote ConnectionDetails for the network adapter used for the test by the selected Agent.
Local Connection

Details for the network adapter used for the test by the local Agent.

Working with the Results of the Network Connectivity Test

Once the test is completed, check for any Agents marked as "Poor" in the Performance column. If such Agents appear, consider the following:

  • Check their machine's hardware for outdated network cards which may need replacement.
  • Examine these machines' network configurations for any differences from machines rated "Good" or "Excellent".
  • Disabling these Agents permanently may have a positive effect on the build performance. The disabled Agent will still be able to run distributed builds, but will not be included in builds initiated by other machines. To keep the "Disabled" state between system reboots, use the Agent Settings dialog box -> Agent->Preferences page.
