Agent Check Agent Check

Supported OS: Linux Mac OS Windows


Extract custom metrics from any prometheus endpoints.

All the metrics retrieved by this integration are considered [custom metrics][7].



The Prometheus check is packaged with the Agent starting version 6.1.0.


Edit the prometheus.d/conf.yaml file to retrieve metrics from applications that expose OpenMetrics / Prometheus end points.

Each instance is at least composed of:

Setting Description
prometheus_url A URL that points to the metric route (Note: must be unique)
namespace This namespace is prepended to all metrics (to avoid metrics name collision)
metrics A list of metrics to retrieve as custom metrics in the form - <METRIC_NAME> or - <METRIC_NAME:RENAME_METRIC>

When listing metrics, it’s possible to use the wildcard * like this - <METRIC_NAME>* to retrieve all matching metrics. Note: use wildcards with caution as it can potentially send a lot of custom metrics.

More advanced settings (ssl, labels joining, custom tags,…) are documented in the sample prometheus.d/conf.yaml

Due to the nature of this integration, it’s possible to submit a high number of custom metrics to Datadog. To provide users control over the maximum number of metrics sent in the case of configuration errors or input changes, the check has a default limit of 2000 metrics. If needed, this limit can be increased by setting the option max_returned_metrics in the prometheus.d/conf.yaml file.

If send_monotonic_counter: True, the Agent sends the deltas of the values in question, and the in-app type is set to count (this is the default behaviour). If send_monotonic_counter: False, the Agent sends the raw, monotonically increasing value, and the in-app type is set to gauge.


Run the Agent’s status subcommand and look for prometheus under the Checks section.
