attachMetadata defines additional metadata which is added to the discovered targets. It requires Prometheus >= v2.35.0.

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

• pattern: (^0|([0-9]*[.])?[0-9]+((K|M|G|T|E|P)i?)?B)$

convertClassicHistogramsToNHCB defines whether to convert all scraped classic histograms into a native histogram with custom buckets. It requires Prometheus >= v3.0.0.

fallbackScrapeProtocol defines the protocol to use if a scrape returns blank, unparseable, or otherwise invalid Content-Type. It requires Prometheus >= v3.0.0.

• enum: ["PrometheusProto","OpenMetricsText0.0.1","OpenMetricsText1.0.0","PrometheusText0.0.4","PrometheusText1.0.0"]

jobLabel defines the label to use to retrieve the job name from. `jobLabel` selects the label from the associated Kubernetes `Pod` object which will be used as the `job` label for all metrics. 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>`).

keepDroppedTargets defines the per-scrape limit on the number of targets dropped by relabeling that will be kept in memory. 0 means no limit. It requires Prometheus >= v2.47.0.

• format: int64
• minimum: 0

labelLimit defines the per-scrape limit on number of labels that will be accepted for a sample. It requires Prometheus >= v2.27.0.

• format: int64
• minimum: 0

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

• format: int64
• minimum: 0

labelValueLengthLimit defines the per-scrape limit on length of labels value that will be accepted for a sample. It requires Prometheus >= v2.27.0.

• format: int64
• minimum: 0

namespaceSelector defines in which namespace(s) Prometheus should discover the pods. By default, the pods are discovered in the same namespace as the `PodMonitor` object but it is possible to select pods across different/all namespaces.

nativeHistogramBucketLimit defines ff there are more than this many buckets in a native histogram, buckets will be merged to stay within the limit. It requires Prometheus >= v2.45.0.

• format: int64
• minimum: 0

nativeHistogramMinBucketFactor defines if the growth factor of one bucket to the next is smaller than this, buckets will be merged to increase the factor sufficiently. It requires Prometheus >= v2.50.0.

• pattern: ^(\+|-)?(([0-9]+(\.[0-9]*)?)|(\.[0-9]+))(([KMGTPE]i)|[numkMGTPE]|([eE](\+|-)?(([0-9]+(\.[0-9]*)?)|(\.[0-9]+))))?$
• x-kubernetes-int-or-string: true

podMetricsEndpoints defines how to scrape metrics from the selected pods.

podTargetLabels defines the labels which are transferred from the associated Kubernetes `Pod` object onto the ingested metrics.

sampleLimit defines a per-scrape limit on the number of scraped samples that will be accepted.

• format: int64
• minimum: 0

scrapeClass defines the scrape class to apply.

• minLength: 1

scrapeClassicHistograms defines whether to scrape a classic histogram that is also exposed as a native histogram. It requires Prometheus >= v2.45.0. Notice: `scrapeClassicHistograms` corresponds to the `always_scrape_classic_histograms` field in the Prometheus configuration.

scrapeNativeHistograms defines whether to enable scraping of native histograms. It requires Prometheus >= v3.8.0.

scrapeProtocols defines the protocols to negotiate during a scrape. It tells clients the protocols supported by Prometheus in order of preference (from most to least preferred). If unset, Prometheus uses its default value. It requires Prometheus >= v2.49.0.

• x-kubernetes-list-type: "set"

selector defines the label selector to select the Kubernetes `Pod` objects to scrape metrics from.

• x-kubernetes-map-type: "atomic"

selectorMechanism defines the mechanism used to select the endpoints to scrape. By default, the selection process relies on relabel configurations to filter the discovered targets. Alternatively, you can opt in for role selectors, which may offer better efficiency in large clusters. Which strategy is best for your use case needs to be carefully evaluated. It requires Prometheus >= v2.17.0.

• enum: ["RelabelConfig","RoleSelector"]

targetLimit defines a limit on the number of scraped targets that will be accepted.

• format: int64
• minimum: 0
