Container metrics

Learn about key container metrics displayed in the Infrastructure app:

Docker container metrics ¶

These are the key metrics displayed for Docker containers.

CPU usage metrics ¶

Metric Description
CPU Usage (%) Average CPU for the container.
Field Calculation: average(docker.cpu.total.pct)

Memory metrics ¶

Metric Description
Memory Usage (%) Average memory usage for the container.
Field Calculation: average(docker.memory.usage.pct)

Network metrics ¶

Metric Description
Inbound Traffic (RX) Derivative of the maximum of docker.network.in.bytes scaled to a 1 second rate.
Field Calculation: average(docker.network.inbound.bytes) * 8 / (max(metricset.period, kql='docker.network.inbound.bytes: *') / 1000)
Outbound Traffic (TX) Derivative of the maximum of docker.network.out.bytes scaled to a 1 second rate.
Field Calculation: average(docker.network.outbound.bytes) * 8 / (max(metricset.period, kql='docker.network.outbound.bytes: *') / 1000)

Disk metrics ¶

Metric Description
Disk Read IOPS Average count of read operations from the device per second.
Field Calculation: counter_rate(max(docker.diskio.read.ops), kql='docker.diskio.read.ops: *')
Disk Write IOPS Average count of write operations from the device per second.
Field Calculation: counter_rate(max(docker.diskio.write.ops), kql='docker.diskio.write.ops: *')

Kubernetes container metrics ¶

These are the key metrics displayed for Kubernetes (containerd) containers.

CPU usage metrics ¶

Metric Description
CPU Usage (%) Average CPU for the container.
Field Calculation: average(kubernetes.container.cpu.usage.limit.pct)

Memory metrics ¶

Metric Description
Memory Usage (%) Average memory usage for the container.
Field Calculation: average(kubernetes.container.memory.usage.limit.pct)
