func AddHTTPSDConfigToPromConfig ¶

func AddHTTPSDConfigToPromConfig(prometheus map[any]any, taServiceName string) (map[any]any, error)

AddHTTPSDConfigToPromConfig adds HTTP SD (Service Discovery) configuration to the Prometheus configuration. This function removes any existing service discovery configurations (e.g., `sd_configs`, `dns_sd_configs`, `file_sd_configs`, etc.) from the `scrape_configs` section and adds a single `http_sd_configs` configuration. The `http_sd_configs` points to the TA (Target Allocator) endpoint that provides the list of targets for the given job.

func AddTAConfigToPromConfig ¶

func AddTAConfigToPromConfig(prometheus map[any]any, taServiceName string, taOpts ...TAOption) (map[any]any, error)

AddTAConfigToPromConfig adds or updates the target_allocator configuration in the Prometheus configuration. If the `EnableTargetAllocatorRewrite` feature flag for the target allocator is enabled, this function removes the existing scrape_configs from the collector's Prometheus configuration as it's not required.

func ConfigToPromConfig ¶

func ConfigToPromConfig(cfg string) (map[any]any, error)

ConfigToPromConfig converts the incoming configuration object into the Prometheus receiver config.

func GetScrapeConfigsFromPromConfig ¶ added in v0.96.0

func GetScrapeConfigsFromPromConfig(promReceiverConfig map[any]any) ([]map[string]any, error)

GetScrapeConfigsFromPromConfig extracts the scrapeConfig array from prometheus receiver config.

func UnescapeDollarSignsInPromConfig ¶

func UnescapeDollarSignsInPromConfig(cfg string) (map[any]any, error)

UnescapeDollarSignsInPromConfig replaces "$$" with "$" in the "replacement" fields of both "relabel_configs" and "metric_relabel_configs" in a Prometheus configuration file.

func ValidatePromConfig ¶

func ValidatePromConfig(config map[any]any, targetAllocatorEnabled bool) error

ValidatePromConfig checks if the prometheus receiver config is valid given other collector-level settings.

func ValidateTargetAllocatorConfig ¶

func ValidateTargetAllocatorConfig(targetAllocatorPrometheusCR bool, promReceiverConfig map[any]any) error

ValidateTargetAllocatorConfig checks if the Target Allocator config is valid In order for Target Allocator to do anything useful, at least one of the following has to be true:

• at least one scrape config has to be defined in Prometheus receiver configuration
• PrometheusCR has to be enabled in target allocator settings
