The following table lists the metrics that the robots collect.

Table 17:Metrics Collected for Teams

Metric Description

Average Mean Opinion Score Global

The average Mean Opinion Score (MOS). A prediction of end-user audio quality experience. It is based on latency, the packet loss, jitter, and the codec used.

% Warning by App

The percentage of warnings related to Teams at each site.

Performance

Indicates the overall health of the Teams service.

Lowest MOS Overall

Displays the lowest MOS score at any site.

95%ile PacketLoss

Packet Loss Rate

The number of packets lost in a 15-second interval. For example, if 1000 packets are sent in a 15-second interval and 50 are lost, the packet loss rate is 5%.

Microsoft recommends a packet loss rate of 1% during a 15-second interval. A packet loss rate between 3% and 7% causes a noticeable impact to call quality. A rate of more than 7% severely impacts the call quality.

The graph shows that 95% of the time, the packet loss is better than the average. The remaining 5% of the time, packet loss is below the average.

95%ile RTT, Jitter by App

Round Trip Latency

The time in milliseconds that it takes a data packet to travel from point A to B and return. It is determined by the physical distance between the two points, the speed of transmission, and the overhead taken by the routers in between.

Average Jitter

The size of the buffer that is needed to store packets before they are reconstructed in the correct order. The value is calculated over a 15-second period.

A low jitter number means that the call connection is good. A large jitter value can cause delay in calls and indicates congestion of the network.

5%ile MOS by App

A prediction of end-user audio quality experience. It is based on latency, the packet loss, jitter, and the codec used. The graph shows that 5% of the time, MOS is below the average.

95%ile Login Time by App (ms)

The time in milliseconds to log into Teams. The graph shows that 95% of the time, the amount of time required to log in was better than the average. The remaining 5% of the time, the amount of time required to log in was slower than the average.

Login Time (ms)

The average time in milliseconds to log into Teams.
