Monitoring

This section of the Control Center lets administrators view performance statistics for their servers and identify bottlenecks or network issues.
It adjusts the amount of data displayed (window) and the frequency of data collection (frequency).
Components of the monitoring windows are as follows:
It shows a graphical representation of the base system load average at time intervals of 1, 5, and 15-minutes. It is a general baseline of system load. If the value of 1-minute is higher than the other two, it indicates that the load is increasing.
It shows a graphical representation of the total amount of system RAM in use, versus available RAM. If memory used approaches 80% of total memory then you should consider closing some sources, particularly interactive sources.
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.
This graph shows a graphical representation of the following parameters:
Total GPU utilization
The load on the encoder, i.e., the video being sent to the uClients.
The load on the decoder, i.e., the video content being ingested from the sources.
If the encoder or decoder usage constantly spikes above 70% to 80%, it is recommended to stop some video sources or use videos of lower resolutions or frame rates.
It shows a graphical representation of the total amount of GPU RAM in use, versus the 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.
This shows a graphical representation of the PCI bandwidth in use by the GPU.
This shows a graphical representation of the data rates that are transmitted and received by the network interface(s).
This shows a graphical representation of the errored, lost, or dropped packets from the network interface(s).
This should show counts of zero or near-zero at all times.
This shows the data volumes that are transmitted and received by the network interface(s).
If any of these graphs show max volume for the interface that is 1 or 10 Gbps then it is recommended that you consider lowering the frame rates or reducing the number of displays served by this server.
