Mesosphere DC/OS collects basic system metrics–such as CPU and memory–for nodes and containers automatically. Mesosphere DC/OS also collects metadata about the different categories of metrics. For more information about the metadata metrics, see Dimensions.

You should note that automatically-collected metrics are only available for containers that provide endpoint statistics. For example, Docker containers do not provide networking data for DC/OS to consume, so the networking metrics that are available for UCR containers are not available for Docker containers.

Node

CPU and memory metrics

Metric	Description
cpu.idle	Percentage of CPUs idle.
cpu.system	Percentage of system used.
cpu.total	Percentage of CPUs used.
cpu.user	Percentage of CPU used by the user.
cpu.wait	Percentage idle while waiting for an operation to complete.
load.1min	Load average for the past minute.
load.5min	Load average for the past 5 minutes.
load.15min	Load average for the past 15 minutes.
memory.buffers	Number of memory buffers.
memory.cached	Amount of cached memory.
memory.free	Amount of free memory in bytes.
memory.total	Total memory in bytes.
process.count	Number of processes that are running.
swap.free	Amount of free swap space.
swap.total	Total swap space.
swap.used	Amount of swap space used.
system.uptime	The system uptime.

File system metrics

Metric	Description
filesystem.capacity.free	Amount of available capacity in bytes.
filesystem.capacity.total	Total capacity in bytes.
filesystem.capacity.used	Capacity used in bytes.
filesystem.inode.free	Amount of available inodes in bytes.
filesystem.inode.total	Total inodes in bytes.
filesystem.inode.used	Inodes used in bytes.

NOTE: The tag path is automatically populated based on the mount path of the local filesystem (for example, /, /boot, etc).

Network interface metrics

Metric	Description
network.in	Number of bytes downloaded.
network.in.dropped	Number of downloaded bytes dropped.
network.in.errors	Number of downloaded bytes in error.
network.in.packets	Number of packets downloaded.
network.out	Number of bytes uploaded.
network.out.dropped	Number of uploaded bytes dropped.
network.out.errors	Number of uploaded bytes in error.
network.out.packets	Number of packets uploaded.

NOTE: The tag interface is automatically populated based on the type of the network interface (for example, spartan, d-dcos, minuteman, etc).

Container

The following per-container resource utilization metrics are collected.

CPU usage metrics

Metric	Description
cpus.limit	The number of CPU shares allocated.
cpus.system_time_secs	Total CPU time spent in kernel mode in seconds.
cpus.throttled_time_secs	Total time, in seconds, that CPU was throttled.
cpus.user_time_secs	Total CPU time spent in user mode.

Disk metrics

Metric	Description
disk.limit_bytes	Hard capacity limit for disk in bytes.
disk.used_bytes	Hard capacity used in bytes.

Memory metrics

Metric	Description
mem.limit_bytes	Hard memory limit for a container.
mem.total_bytes	Total memory of a process in RAM (as opposed to in swap).

Network metrics

Metric	Description
net.rx.bytes	Bytes received.
net.rx.dropped	Packets dropped on receive.
net.rx.errors	Errors reported on receive.
net.rx.packets	Packets received.
net.tx.bytes	Bytes sent.
net.tx.dropped	Packets dropped on send.
net.tx.errors	Errors reported on send.
net.tx.packets	Packets sent.

Dimensions

Dimensions are metadata about the metrics. The following table lists the available dimensions and the entities where they appear.

Dimension	Description	Entity
mesos_id	The Mesos ID of the node.	node, container
cluster_id	The ID of the Mesos cluster.	node, container
container_id	The ID of the container.	metric, container
executor_name	The name of the task executor.	metric
framework_name	The name of the framework.	container
hostname	The IP address of the node.	container, node
labels	Key-value pairs describing the metric.	container
task_name	The task name.	container
