System Metrics

Subscribing to system metrics will display a graphical visualization (like a graph with metrics data plotted along x-axis and time along the y-axis) of the metrics.

Read the metrics reference to know the data fields included in each system metric.

Network IO Interface

You can monitor and analyze real-time network performance metrics. For instance, you can collect upload and download rate per second for all interfaces for the last hour. The metrics reference includes the kind of data measured in a network IO graph.

Disk usage

Subscribing to disk usage metrics displays a graph that shows the information on disk usage metrics like available disk space, percentage of disk space used, etc. Read more to know the kind of disk usage metrics that are collected.

Disk IO

You can gather metrics about disk traffic and timing by subscribing to the disk IO. Read more to know the kind of information collected by disk IO metric.

Memory usage

You can collect and visualize device memory metrics by subscribing to the memory usage system metric. To know more about the data fields associated with memory usage, read here.

CPU load average

You can determine the percentage of CPU used by a user, process, or system by subscribing to the CPU load average metric. Read the CPU load average reference to understand the several data measurements plotted in the graph.

Wireless

You can monitor and analyze the signal strength of a wifi connection by subscribing to the wireless metric. This information is extracted from /proc/net/wireless when a device is connected to a wifi connection. Read the wireless reference to understand what kind of data will be collected when it is subscribed.
