Combining Data Associated with Hardware Resources and Application Transactions

To monitor networked application transactions, the application transactions are sampled and data related thereto are collected. The collected data is associated with a global network identifier corresponding to one or more physical or virtual network interface devices. One or more subsets of the collected data are transmitted in packets. The global network identifier may be a layer 4 socket, one or more MAC address associated with one or more physical or virtual interface devices, or one or more SNMP ifIndex associated with one or more physical or virtual interface devices. Data related to network components are optionally collected and combined with the data related to network components that share the global network identifier associated with the application transaction. The combined data is analyzed to determine one or more network resources associated with the application or at least one statistical characteristic of the networked application.
