CHAPTER 13: DASHBOARD
4. Dropped Frames— the current number of dropped frames summed across all active connections in frames-per-seconds.
The graph portion of the Dropped Frames indicator shows the minimum, maximum and average number of Dropped Frames across
all active connection over the last 24 hours and a graph of Dropped Frames across all active connection over the last 24 hours.
13.2 ACTIVE CONNECTIONS
The Active Connections section of the dashboard displays the currently active connections in the managed domain. The table
portion provides a sortable list of the active connections. Each column can be used to sort the table—in ascending or descending
order—just click on a column header to sort and click again to invest sort order. The filter box at the top right of the table will filter
the table based on the filter box contents.
The first five columns of the table are fixed for all the tabs that can be selected (Network Bandwidth, User Response, Dropped
Frames or Roundtrip Time). The columns are defined as:
Š Connection Name—the name of the active connection
Š
Š User Name—the user name logged into the Receiver that has initiated the active connection
Š
Š Receiver—the name of the Receiver on the active connection
Š
Š Transmitter—the name of the Transmitter on the active connection
Š
Š FPS—the current frames per second being encoded/transferred on the connection
Š
The contents of the last column in the table will vary depending on the tab selected—Network Bandwidth, User Response, Dropped
Frames or Roundtrip Time.
The last column displays when the selected tab is:
Š Network Bandwidth—the total network bandwidth that this connection is generating (in Mbps). Typically, 0 Mbps for a static screen
Š
and <35 Mbps when playing a 1080p video.
Š User-Response Time—the time it takes for an event on the server to be displayed on the Monitor attached to the receiver. This
Š
includes video encode time in the Transmitter, network latency and video decode time in the Receiver as part of its calculation (in
milliseconds). Typically 8–16 ms but can grow to 20–30 ms on congested networks due to dropped frames.
Š Dropped Frames—the number of dropped frames in the Transmitter that is part of this connection. Dropped frames usually result
Š
from network congestion (in frames-per-second). Typically will be 0 fps.
Š Round-trip time—measures the network round-trip time experienced at an IP packet level for the active connection (in milliseconds).
Š
Typically this will be 0 ms on a gigabit network with low congestion.
The graph part of the Active Connections dashboard displays a graph of the last column over time, so it can be network bandwidth,
user-response time, dropped frames per second or roundtrip time.
