Prometheus [monitoring.coreos.com/v1]

additionalAlertManagerConfigs

object

AdditionalAlertManagerConfigs allows specifying a key of a Secret containing additional Prometheus AlertManager configurations. AlertManager configurations specified are appended to the configurations generated by the Prometheus Operator. Job configurations specified must have the form as specified in the official Prometheus documentation: https://prometheus.io/docs/prometheus/latest/configuration/configuration/#alertmanager_config. As AlertManager configs are appended, the user is responsible to make sure it is valid. Note that using this feature may expose the possibility to break upgrades of Prometheus. It is advised to review Prometheus release notes to ensure that no incompatible AlertManager configs are going to break Prometheus after the upgrade.

additionalAlertRelabelConfigs

object

AdditionalAlertRelabelConfigs allows specifying a key of a Secret containing additional Prometheus alert relabel configurations. Alert relabel configurations specified are appended to the configurations generated by the Prometheus Operator. Alert relabel configurations specified must have the form as specified in the official Prometheus documentation: https://prometheus.io/docs/prometheus/latest/configuration/configuration/#alert_relabel_configs. As alert relabel configs are appended, the user is responsible to make sure it is valid. Note that using this feature may expose the possibility to break upgrades of Prometheus. It is advised to review Prometheus release notes to ensure that no incompatible alert relabel configs are going to break Prometheus after the upgrade.

additionalArgs

array

AdditionalArgs allows setting additional arguments for the Prometheus container. It is intended for e.g. activating hidden flags which are not supported by the dedicated configuration options yet. The arguments are passed as-is to the Prometheus container which may cause issues if they are invalid or not supported by the given Prometheus version. In case of an argument conflict (e.g. an argument which is already set by the operator itself) or when providing an invalid argument the reconciliation will fail and an error will be logged.

additionalArgs[]

object

Argument as part of the AdditionalArgs list.

additionalScrapeConfigs

object

AdditionalScrapeConfigs allows specifying a key of a Secret containing additional Prometheus scrape configurations. Scrape configurations specified are appended to the configurations generated by the Prometheus Operator. Job configurations specified must have the form as specified in the official Prometheus documentation: https://prometheus.io/docs/prometheus/latest/configuration/configuration/#scrape_config. As scrape configs are appended, the user is responsible to make sure it is valid. Note that using this feature may expose the possibility to break upgrades of Prometheus. It is advised to review Prometheus release notes to ensure that no incompatible scrape configs are going to break Prometheus after the upgrade.

containers

array

Containers allows injecting additional containers or modifying operator generated containers. This can be used to allow adding an authentication proxy to a Prometheus pod or to change the behavior of an operator generated container. Containers described here modify an operator generated container if they share the same name and modifications are done via a strategic merge patch. The current container names are: prometheus, config-reloader, and thanos-sidecar. Overriding containers is entirely outside the scope of what the maintainers will support and by doing so, you accept that this behaviour may break at any time without notice.

containers[]

object

A single application container that you want to run within a pod.

disableCompaction

boolean

Disable prometheus compaction.

enableAdminAPI

boolean

Enable access to prometheus web admin API. Defaults to the value of false. WARNING: Enabling the admin APIs enables mutating endpoints, to delete data, shutdown Prometheus, and more. Enabling this should be done with care and the user is advised to add additional authentication authorization via a proxy to ensure only clients authorized to perform these actions can do so. For more information see https://prometheus.io/docs/prometheus/latest/querying/api/#tsdb-admin-apis

enableFeatures

array (string)

Enable access to Prometheus disabled features. By default, no features are enabled. Enabling disabled features is entirely outside the scope of what the maintainers will support and by doing so, you accept that this behaviour may break at any time without notice. For more information see https://prometheus.io/docs/prometheus/latest/disabled_features/

enableRemoteWriteReceiver

boolean

Enable Prometheus to be used as a receiver for the Prometheus remote write protocol. Defaults to the value of false. WARNING: This is not considered an efficient way of ingesting samples. Use it with caution for specific low-volume use cases. It is not suitable for replacing the ingestion via scraping and turning Prometheus into a push-based metrics collection system. For more information see https://prometheus.io/docs/prometheus/latest/querying/api/#remote-write-receiver Only valid in Prometheus versions 2.33.0 and newer.

enforcedBodySizeLimit

string

EnforcedBodySizeLimit defines the maximum size of uncompressed response body that will be accepted by Prometheus. Targets responding with a body larger than this many bytes will cause the scrape to fail. Example: 100MB. If defined, the limit will apply to all service/pod monitors and probes. This is an experimental feature, this behaviour could change or be removed in the future. Only valid in Prometheus versions 2.28.0 and newer.

enforcedLabelLimit

Per-scrape limit on number of labels that will be accepted for a sample. If more than this number of labels are present post metric-relabeling, the entire scrape will be treated as failed. 0 means no limit. Only valid in Prometheus versions 2.27.0 and newer.

enforcedLabelNameLengthLimit

integer

Per-scrape limit on length of labels name that will be accepted for a sample. If a label name is longer than this number post metric-relabeling, the entire scrape will be treated as failed. 0 means no limit. Only valid in Prometheus versions 2.27.0 and newer.

enforcedLabelValueLengthLimit

integer

Per-scrape limit on length of labels value that will be accepted for a sample. If a label value is longer than this number post metric-relabeling, the entire scrape will be treated as failed. 0 means no limit. Only valid in Prometheus versions 2.27.0 and newer.

enforcedNamespaceLabel

Label name is this field’s value. Label value is the namespace of the created object (mentioned above).

enforcedSampleLimit

integer

EnforcedSampleLimit defines global limit on number of scraped samples that will be accepted. This overrides any SampleLimit set per ServiceMonitor or/and PodMonitor. It is meant to be used by admins to enforce the SampleLimit to keep overall number of samples/series under the desired limit. Note that if SampleLimit is lower that value will be taken instead.

enforcedTargetLimit

integer

EnforcedTargetLimit defines a global limit on the number of scraped targets. This overrides any TargetLimit set per ServiceMonitor or/and PodMonitor. It is meant to be used by admins to enforce the TargetLimit to keep the overall number of targets under the desired limit. Note that if TargetLimit is lower, that value will be taken instead, except if either value is zero, in which case the non-zero value will be used. If both values are zero, no limit is enforced.

initContainers

array

InitContainers allows adding initContainers to the pod definition. Those can be used to e.g. fetch secrets for injection into the Prometheus configuration from external sources. Any errors during the execution of an initContainer will lead to a restart of the Pod. More info: https://kubernetes.io/docs/concepts/workloads/pods/init-containers/ InitContainers described here modify an operator generated init containers if they share the same name and modifications are done via a strategic merge patch. The current init container name is: init-config-reloader.

object

PrometheusRuleExcludeConfig enables users to configure excluded PrometheusRule names and their namespaces to be ignored while enforcing namespace label for alerts and metrics.

query

object

QuerySpec defines the query command line flags when starting Prometheus.

queryLogFile

string

QueryLogFile specifies the file to which PromQL queries are logged. If the filename has an empty path, e.g. 'query.log', prometheus-operator will mount the file into an emptyDir volume at /var/log/prometheus. If a full path is provided, e.g. /var/log/prometheus/query.log, you must mount a volume in the specified directory and it must be writable. This is because the prometheus container runs with a read-only root filesystem for security reasons. Alternatively, the location can be set to a stdout location such as /dev/stdout to log query information to the default Prometheus log stream. This is only available in versions of Prometheus >= 2.16.0. For more details, see the Prometheus docs (https://prometheus.io/docs/guides/query-log/)

retentionSize

string

Maximum amount of disk space used by blocks.

routePrefix

string

The route prefix Prometheus registers HTTP handlers for. This is useful, if using ExternalURL and a proxy is rewriting HTTP routes of a request, and the actual ExternalURL is still true, but the server serves requests under a different route prefix. For example for use with kubectl proxy.

shards

integer

EXPERIMENTAL: Number of shards to distribute targets onto. Number of replicas multiplied by shards is the total number of Pods created. Note that scaling down shards will not reshard data onto remaining instances, it must be manually moved. Increasing shards will not reshard data either but it will continue to be available from the same instances. To query globally use Thanos sidecar and Thanos querier or remote write data to a central location. Sharding is done on the content of the address target meta-label.

preferredDuringSchedulingIgnoredDuringExecution

array

The scheduler will prefer to schedule pods to nodes that satisfy the affinity expressions specified by this field, but it may choose a node that violates one or more of the expressions. The node that is most preferred is the one with the greatest sum of weights, i.e. for each node that meets all of the scheduling requirements (resource request, requiredDuringScheduling affinity expressions, etc.), compute a sum by iterating through the elements of this field and adding "weight" to the sum if the node matches the corresponding matchExpressions; the node(s) with the highest sum are the most preferred.
