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
| Type | Description | Quantiles |
|---|---|---|
| Gauge | Gauge types report an absolute number at the end of the aggregation interval | false |
| Counter | Counts are incremented and flushed at the end of the aggregation interval and then are reset to zero | true |
| Timer | Timers 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.
Additional labels are emitted 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.
| Label | Value |
|---|---|
| job | myjob/dispatch-1312323423423 |
| parent_id | myjob |
| dispatch_id | 1312323423423 |
