Chapter 6. PodMonitor [monitoring.coreos.com/v1]

attachMetadata

object

attachMetadata defines additional metadata which is added to the discovered targets. It requires Prometheus >= v2.37.0.

string

When defined, bodySizeLimit specifies a job level limit on the size of uncompressed response body that will be accepted by Prometheus. It requires Prometheus >= v2.28.0.

For example if jobLabel is set to foo and the Kubernetes Pod object is labeled with foo: bar, then Prometheus adds the job="bar" label to all ingested metrics. If the value of this field is empty, the job label of the metrics defaults to the namespace and name of the PodMonitor object (e.g. <namespace>/<name>).

integer

Per-scrape limit on length of labels name that will be accepted for a sample. It requires Prometheus >= v2.27.0.

dryRun

string

When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed

fieldValidation

string

fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered.
