Active and Passive: It is possible to have it all-in-one
Increasingly, enterprise IT operations teams and service providers require the complementary technologies of active and passive monitoring. Only by implementing both will IT operations teams be able to gain a full, end-to-end view of what is happening from overall network performance to application transaction-level activity. This is especially important for large, more complex networks migrating to the cloud. IT managers will need to conduct both traffic capture and analysis, as well as, active testing which provides visibility over WAN and cloud environments.
It is would be useful to revisit the benefits of each to see why having this combined view is critical to optimize network performance.
