serverName:
description: Used to verify the hostname for the targets.
type: string
type: object
trackTimestampsStaleness:
description: |-
`trackTimestampsStaleness` defines whether Prometheus tracks staleness of
the metrics that have an explicit timestamp present in scraped data.
Has no effect if `honorTimestamps` is false.
It requires Prometheus >= v2.48.0.
type: boolean
type: object
type: array
jobLabel:
description: |-
`jobLabel` selects the label from the associated Kubernetes `Service`
object which will be used as the `job` label for all metrics.
For example if `jobLabel` is set to `foo` and the Kubernetes `Service`
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 or if the label doesn't exist for
the given Service, the `job` label of the metrics defaults to the name
of the associated Kubernetes `Service`.
type: string
keepDroppedTargets:
description: |-
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
type: integer
labelLimit:
description: |-
Per-scrape limit on number of labels that will be accepted for a sample.
It requires Prometheus >= v2.27.0.
format: int64
type: integer
labelNameLengthLimit:

Per-scrape limit on length of labels name that will be accepted for a sample.
It requires Prometheus >= v2.27.0.
format: int64
type: integer

description: |-
Per-scrape limit on length of labels value that will be accepted for a sample.
It requires Prometheus >= v2.27.0.
format: int64
type: integer
namespaceSelector:
description: |-
Selector to select which namespaces the Kubernetes `Endpoints` objects
are discovered from.
properties:
any:
description: |-
Boolean describing whether all namespaces are selected in contrast to a
list restricting them.
type: boolean
matchNames:
description: List of namespace names to select from.
items:

type: array
type: object
podTargetLabels:
description: |-
`podTargetLabels` defines the labels which are transferred from the
associated Kubernetes `Pod` object onto the ingested metrics.
items:
type: string
type: array
sampleLimit:
description: |-
`sampleLimit` defines a per-scrape limit on the number of scraped samples
that will be accepted.
format: int64
type: integer
scrapeClass:
description: The scrape class to apply.
minLength: 1
type: string
scrapeProtocols:
description: |-
`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.
items:
description: |-
ScrapeProtocol represents a protocol used by Prometheus for scraping metrics.
Supported values are:
* `OpenMetricsText0.0.1`
* `OpenMetricsText1.0.0`
* `PrometheusProto`
* `PrometheusText0.0.4`

- PrometheusProto
- OpenMetricsText0.0.1
- OpenMetricsText1.0.0
- PrometheusText0.0.4

selector:
description: Label selector to select the Kubernetes `Endpoints` objects.
properties:
matchExpressions:
description: matchExpressions is a list of label selector requirements.
The requirements are ANDed.
items:
description: |-
A label selector requirement is a selector that contains values, a key, and an operator that
relates the key and values.
properties:
key:
description: key is the label key that the selector applies
to.
type: string
operator:
description: |-
operator represents a key's relationship to a set of values.
Valid operators are In, NotIn, Exists and DoesNotExist.
type: string
values:
description: |-
values is an array of string values. If the operator is In or NotIn,
the values array must be non-empty. If the operator is Exists or DoesNotExist,
the values array must be empty. This array is replaced during a strategic
merge patch.
items:

matchLabels:
additionalProperties:
type: string
description: |-
matchLabels is a map of {key,value} pairs. A single {key,value} in the matchLabels
map is equivalent to an element of matchExpressions, whose key field is "key", the
operator is "In", and the values array contains only "value". The requirements are ANDed.
