These metrics are automatically collected by DC/OS.


CPU and memory metrics

Metric Description
cpu.cores Percentage of cores used.
cpu.idle Percentage of CPUs idle.
cpu.system Percentage of system used. 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. Amount of free memory in bytes. Total memory in bytes.
process.count Number of processes that are running. Amount of free swap space. Total swap space.
swap.used Amount of swap space used.
system.uptime The system reliability and load average.

Filesystem metrics

Metric Description Amount of available capacity in bytes. Total capacity in bytes.
filesystem.capacity.used Capacity used in bytes. Amount of available inodes in bytes. 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 (e.g., /, /boot, etc).

Network interface metrics

Metric Description Number of bytes downloaded. Number of downloaded bytes dropped. Number of downloaded bytes in error. Number of packets downloaded.
network.out.bytes 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 (e.g., spartan, d-dcos, minuteman, etc).


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 Total CPU time spent in kernel mode in seconds.
cpus.throttled.time Total time, in seconds, that CPU was throttled.
cpus.user.time Total CPU time spent in user mode.

Disk metrics

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

Memory metrics

Metric Description
mem.limit Hard memory limit for a container. 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 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_id The ID of the task executor. metric, container
executor_name The name of the task executor. metric
framework_id The ID of the framework. metric, container
framework_name The name of the framework. container
framework_principal The principal of the framework. container
framework_role The framework role. container
hostname The IP address of the node. container, node
labels Key-value pairs describing the metric. container
source The source of the metric. Equivalent to the executor ID. metric
task_id The task ID. container
task_name The task name. container
