The Hardware dashboard lets you monitor CPU usage, disk throughput, network traffic, storage capacity, and memory. To view this dashboard, access the Admin UI, click Metrics on the left, and then select Dashboard > Hardware.
The Hardware dashboard displays the following time series graphs:
-
In the node view, the graph shows the percentage of CPU in use by the CockroachDB process for the selected node.
-
In the cluster view, the graph shows the percentage of CPU in use by the CockroachDB process across all nodes.
{{site.data.alerts.callout_info}} For multi-core systems, the percentage of CPU usage is calculated by normalizing the CPU usage across all cores, whereby 100% utilization indicates that all cores are fully utilized. {{site.data.alerts.end}}
-
In the node view, the graph shows the memory in use by CockroachDB for the selected node.
-
In the cluster view, the graph shows the memory in use by CockroachDB across all nodes in the cluster.
-
In the node view, the graph shows the 10-second average of the number of bytes read per second by all processes, including CockroachDB, for the selected node.
-
In the cluster view, the graph shows the 10-second average of the number of bytes read per second by all processes, including CockroachDB, across all nodes.
-
In the node view, the graph shows the 10-second average of the number of bytes written per second by all processes, including CockroachDB, for the node.
-
In the cluster view, the graph shows the 10-second average of the number of bytes written per second by all processes, including CockroachDB, across all nodes.
-
In the node view, the graph shows the 10-second average of the number of disk read ops per second for all processes, including CockroachDB, for the selected node.
-
In the cluster view, the graph shows the 10-second average of the number of disk read ops per second for all processes, including CockroachDB, across all nodes.
-
In the node view, the graph shows the 10-second average of the number of disk write ops per second for all processes, including CockroachDB, for the node.
-
In the cluster view, the graph shows the 10-second average of the number of disk write ops per second for all processes, including CockroachDB, across all nodes.
-
In the node view, the graph shows the number of disk reads and writes in queue for all processes, including CockroachDB, for the selected node.
-
In the cluster view, the graph shows the number of disk reads and writes in queue for all processes, including CockroachDB, across all nodes in the cluster.
{{site.data.alerts.callout_info}} For Mac OS, this graph is not populated and shows zero disk IOPS in progress. This is a known limitation that may be lifted in the future. {{site.data.alerts.end}}
-
In the node view, the graph shows the available storage capacity for the selected node.
-
In the cluster view, the graph shows the available storage capacity across all nodes in the cluster.

-
In the node view, the graph shows the 10-second average of the number of network bytes received per second for all processes, including CockroachDB, for the node.
-
In the cluster view, the graph shows the 10-second average of the number of network bytes received for all processes, including CockroachDB, per second across all nodes.
-
In the node view, the graph shows the 10-second average of the number of network bytes sent per second by all processes, including CockroachDB, for the node.
-
In the cluster view, the graph shows the 10-second average of the number of network bytes sent per second by all processes, including CockroachDB, across all nodes.
