Types

type Config

type Config struct {
	// Common cadvisor config options
	// StoreContainerLabels converts container labels and environment variables into labels on prometheus metrics for each container. If false, then only metrics exported are container name, first alias, and image name.
	StoreContainerLabels bool `yaml:"store_container_labels,omitempty"`

	// AllowlistedContainerLabels list of container labels to be converted to labels on prometheus metrics for each container. store_container_labels must be set to false for this to take effect.
	AllowlistedContainerLabels []string `yaml:"allowlisted_container_labels,omitempty"`

	// EnvMetadataAllowlist list of environment variable keys matched with specified prefix that needs to be collected for containers, only support containerd and docker runtime for now.

	RawCgroupPrefixAllowlist []string `yaml:"raw_cgroup_prefix_allowlist,omitempty"`

	// PerfEventsConfig path to a JSON file containing configuration of perf events to measure. Empty value disabled perf events measuring.

	// DisableMetrics list of `metrics` to be disabled.
	DisabledMetrics []string `yaml:"disabled_metrics,omitempty"`

	// EnableMetrics list of `metrics` to be enabled. If set, overrides 'disable_metrics'.
	EnabledMetrics []string `yaml:"enabled_metrics,omitempty"`

	// StorageDuration length of time to keep data stored in memory (Default: 2m)
	StorageDuration time.Duration `yaml:"storage_duration,omitempty"`

	// Containerd config options
	// Containerd containerd endpoint
	Containerd string `yaml:"containerd,omitempty"`

	// ContainerdNamespace containerd namespace
	ContainerdNamespace string `yaml:"containerd_namespace,omitempty"`

	// Docker config options
	// Docker docker endpoint
	Docker string `yaml:"docker,omitempty"`

Config controls cadvisor

func (*Config) GetIncludedMetrics

func (c *Config) GetIncludedMetrics() (container.MetricSet, error)

GetIncludedMetrics applies some logic to determine the final set of metrics to be scraped and returned by the cAdvisor integration

func (*Config) InstanceKey

func (c *Config) InstanceKey(agentKey string) (string, error)

InstanceKey returns the agentKey

func (*Config) Name

func (c *Config) Name() string

Name returns the name of the integration that this config represents.

func (*Config) NewIntegration

func (c *Config) NewIntegration(logger log.Logger) (integrations.Integration, error)

NewIntegration creates a new cadvisor integration

func (*Config) UnmarshalYAML

func (c *Config) UnmarshalYAML(unmarshal func(interface{}) error) error

UnmarshalYAML implements yaml.Unmarshaler for Config
