This section of Control Center lets administrators view performance statistics for their server and identify bottlenecks or network issues.
Adjust the amount of data displayed (Window) and the frequency of data collection (Frequency).
1, 5, and 15-minute graphs showing the base system Load Average.
This is a general baseline of system load. If 1-minute is higher than the other two, load is increasing.
Total amount of system RAM in use, versus available.
If Memory Used approaches 80% of Memory Total then you may wish to consider closing some Sources, particularly Interactive ones.
Average total CPU usage (blue fill) versus individual CPU core usage (lines)
If the blue fill approaches 90%, then you may wish to consider closing some Sources. If several CPU cores are at 100%, you may be running some Interactive Sources (web browsers, VNC) that are running a high amount of video.
Total GPU usage (blue fill) along with the load on the Encoder (video being sent to uClients) and Decoder (video content being ingested from Sources)
If Encoder or Decoder usage constantly spikes above 70% to 80%, you may wish to consider stopping some video sources or using lower resolutions or frame rates.
Total amount of GPU RAM in use, versus available.
Memory Used should never approach Memory Total unless you are using an Nvidia GPU with under 4GB of VRAM, which is not supported or recommended.
PCI bandwidth in use by the GPU.
Data rates transmitted and received by the network interface(s).
Errored, lost, or dropped packets from the network interface(s).
This should show counts of zero or near-zero at all times.
Network Send/Receive - I/O
Data volumes transmitted and received by the network interface(s).
If any of these graphs show max volume for the interfact (1 or 10 Gbps) then you may wish to consider lowering frame rates or reducing the number of displays served by this server.
