What does local connectivity measure in a network environment?

Local connectivity in a network environment primarily measures the percentage of processes that successfully establish TCP connections. This metric is crucial for understanding how well applications and services are communicating within a specific network segment.

Reliably establishing TCP connections is essential for the functionality of many applications, as it indicates that devices within the network can reach each other effectively. High percentages in this metric suggest a healthy network state, with minimal issues affecting the ability of processes to communicate. Therefore, monitoring local connectivity helps in assessing the performance and stability of application interactions in real-time.

The other options, while related to network performance, measure different aspects. The rate of network errors tracks issues encountered during data transmission, the number of retransmissions indicates how often data packets need to be sent again due to loss, and overall bandwidth used provides insight into the volume of data being transferred. However, none of these directly measures the success rate of establishing connections, which is the primary focus of local connectivity.
