Computers may switch between networks. A laptop, for example, may be connected to several different networks during a day.

Example: Paul works at the Manchester office, but he often travels to the Paris office for meetings. During a busy working day Paul's computer may thus be connected to the Manchester office network, the Manchester airport public wi-fi network, the Paris office network, the Paris airport public wi-fi network, the Manchester office network again, and finally to Paul's own home network.

Because PerformanceGuard automatically places computers in groups based on the computers' network details (see Network Grouping), you'll see that computers move between groups when they move between networks.

With PerformanceGuard you can keep track of a computer's network history: Select ANALYZE > Computers > Computer Search, and search for a computer. Then, in the search results, click the name of the required computer, and then select the Network History tab.

The network history information consists of group description (for example Agents in network 192.168.101.0/24) and a time stamp that indicates when the computer first reported that it was connected to the network in question.

If users on the move complain about latency or similar problems at certain locations, the network history may help you pinpoint the problem. If we look at the previous example, Paul's computer might connect to the low-bandwidth guest network when he is at the Paris office. If you spot that, you could help Paul by changing his setup so that he connects to the high-bandwidth employee network instead.

Remember that you can also create your own groups that are not based on computers' network details. Computers can belong to more than one group, so if required you can create your own groups for computers that use specific applications or operating systems, computers in particular regions, states or countries, etc. Computers won't move between such groups when they move between networks.
