»Metrics Reference

The Nomad agent collects various runtime metrics about the performance of different libraries and subsystems. These metrics are aggregated on a ten second interval and are retained for one minute.

This data can be accessed via an HTTP endpoint or via sending a signal to the Nomad process. This data is available via HTTP at /metrics. See Metrics for more information.

To view this data via sending a signal to the Nomad process: on Unix, this is USR1 while on Windows it is BREAK. Once Nomad receives the signal, it will dump the current telemetry information to the agent's stderr.

This telemetry information can be used for debugging or otherwise getting a better view of what Nomad is doing.

Telemetry information can be streamed to both statsite as well as statsd based on providing the appropriate configuration options.

To configure the telemetry output please see the agent configuration.

Below is sample output of a telemetry dump:

»Metric Types

TypeDescriptionQuantiles
GaugeGauge types report an absolute number at the end of the aggregation intervalfalse
CounterCounts are incremented and flushed at the end of the aggregation interval and then are reset to zerotrue
TimerTimers measure the time to complete a task and will include quantiles, means, standard deviation, etc per interval.true

»Tagged Metrics

Nomad emits metrics in a tagged format. Each metric can support more than one tag, meaning that it is possible to do a match over metrics for datapoints such as a particular datacenter, and return all metrics with this tag. Nomad supports labels for namespaces as well.

»Key Metrics

The metrics in the table below are the most important metrics for monitoring the overall health of a Nomad cluster.

When telemetry is being streamed to statsite or statsd, interval in the table below is defined to be their flush interval. Otherwise, the interval can be assumed to be 10 seconds when retrieving metrics using the above described signals.

»Client Metrics

The Nomad client emits metrics related to the resource usage of the allocations and tasks running on it and the node itself. Operators have to explicitly turn on publishing host and allocation metrics. Publishing allocation and host metrics can be turned on by setting the value of publish_allocation_metrics publish_node_metrics to true.

By default the collection interval is 1 second but it can be changed by the changing the value of the collection_interval key in the telemetry configuration block.

Please see the agent configuration page for more details.

As of Nomad 0.9, Nomad will emit additional labels for parameterized and periodic jobs. Nomad emits the parent job id as a new label parent_id. Also, the labels dispatch_id and periodic_id are emitted, containing the ID of the specific invocation of the parameterized or periodic job respectively. For example, a dispatch job with the id myjob/dispatch-1312323423423, will have the following labels.

LabelValue
jobmyjob/dispatch-1312323423423
parent_idmyjob
dispatch_id1312323423423
