Measures reported by SaaSNetworkTest
This is an external test that emulates a network-level ping to the cloud-based Exchange server and reports whether/not network connectivity to the server is available, and if so, how responsive the server is to network requests. In the process, the test reveals any break or slowness in the network connection to the Exchange Online service.
Outputs of the test: One set of results for the Exchange server on the cloud
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| Avg_delay |
Indicates the average delay between transmission of packet to the server and receipt of the response to the packet at the source. |
Seconds |
An increase in network latency could result from misconfiguration of the router(s) along the path, network congestion, retransmissions at the network, etc.
|
| Min_delay |
The minimum time between transmission of a packet and receipt of the response back from the server. |
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 server 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.
|
| Availability |
Indicates whether the network connection to the target server is available or not |
Percent |
A value of 100 indicates that the server is connected over the network. The value 0 indicates that the server is not connected.
Typically, the value 100 corresponds to a Packet loss of 0.
