Description |
Measurement Unit |
Interpretation |
| Availability |
Indicates whether/not the network connection is available. |
Percent |
A value of 100 indicates that the system is connected. The value 0 indicates that the system is not connected.
Typically, the value 100 corresponds to a packet loss of 0. |
| Avg_delay |
Indicates the average delay between transmission of packets and receipt of the response to the packet at the source. |
Seconds |
Ideally, value of this measure should be low. |
| Min_delay |
Indicates the minimum time between transmission of a packet and receipt of the response back. |
Seconds |
A significant increase in the minimum round-trip time is often a sure sign of network congestion. |
| Pkt_loss_pct |
Indicates the percentage of packets lost during transmission from source to target and back. |
Percent |
Packet loss is often caused by network buffer overflows at a network router or by packet corruptions over the network. The detailed diagnosis for this measure provides a listing of routers that are on the path from the external agent to target server, and the delays on each hop. This information can be used to diagnose the hop(s) that could be causing excessive packet loss/delays. |
