add-graphite-reporter clj

(add-graphite-reporter registry-context graphite-config metrics-allowed domain)

Inputs: [registry-context :- RegistryContext graphite-config :- (schema/maybe GraphiteReporterConfig) metrics-allowed :- #{schema/Str} domain :- schema/Keyword] Returns: RegistryContext

Adds a graphite reporter to the given registry context if graphite is enabled in the configuration. Starts up a thread which reports the metrics to graphite on the interval specified in :update-interval-seconds

add-graphite-reporters clj

(add-graphite-reporters service-context)

Inputs: [service-context :- MetricsServiceContext] Returns: MetricsServiceContext

Add Graphite reporters to all registries with Graphite enabled in the config, using the configured settings for each registry. Returns an updated service context. Should be called from start of the metrics-service.

BaseGraphiteReporterConfig clj

build-graphite-reporter clj

(build-graphite-reporter registry metrics-allowed graphite-sender)

Inputs: [registry :- MetricRegistry metrics-allowed :- #{schema/Str} graphite-sender :- GraphiteSender] Returns: GraphiteReporter

Constructs a GraphiteReporter instance for the given registry, with the given allowed metrics, and using the given graphite-sender

build-graphite-sender clj

(build-graphite-sender graphite-config domain)

Inputs: [graphite-config :- GraphiteReporterConfig domain :- schema/Keyword] Returns: GraphiteSender

build-handler clj

(build-handler path)

build-metric-filter clj

(build-metric-filter metrics-allowed)

Inputs: [metrics-allowed :- #{schema/Str}] Returns: AllowedNamesMetricFilter

construct-metric-names clj

(construct-metric-names prefix metric-names)

Inputs: [prefix :- schema/Str metric-names :- [schema/Str]] Returns: #{schema/Str}

Prefixes the metric prefix to each metric name. Returns a set of metric names (duplicates are removed).

create-initial-service-context clj

(create-initial-service-context metrics-config)

Inputs: [metrics-config :- MetricsConfig] Returns: MetricsServiceContext

Create the initial service context for the metrics-service. Initialize all registries in the config, add them to the registries atom, and include that in the service context map, along with an empty atom for registry-settings and the metrics config.

default-middleware clj

(default-middleware)

Inputs: []

DefaultRegistrySettings clj

get-graphite-config clj

(get-graphite-config config domain)

Inputs: [config :- MetricsConfig domain :- schema/Keyword] Returns: (schema/maybe GraphiteReporterConfig)

Merge together the graphite config for the registry with the global graphite config.

get-metric-prefix clj

(get-metric-prefix metrics-config domain)

Inputs: [metrics-config :- MetricsConfig domain :- schema/Keyword] Returns: schema/Str

Determines what the metric prefix should be. If a metric-prefix is set in the config, we use that. Else default to the server-id

get-metrics-allowed clj

(get-metrics-allowed metrics-config registry-settings domain)

Inputs: [metrics-config :- MetricsConfig registry-settings :- #:schema{Any DefaultRegistrySettings} domain :- schema/Keyword] Returns: #{schema/Str}

Get the metrics allowed for the registry. Looks at the metrics-allowed registered for the registry in the registry settings atom using the update-registry-settings function as well as the metrics-allowed listed in the config file under the :metrics-allowed key. Merges these lists together and then adds the metrics prefix to them, returning a set of prefixed allowed metrics.

get-or-initialize-registry-context clj

(get-or-initialize-registry-context {:keys [registries metrics-config]} domain)

Inputs: [{:keys [registries metrics-config]} :- MetricsServiceContext domain :- schema/Keyword] Returns: RegistryContext

If a registry exists within the service context for a given domain already, return it. Otherwise initialize a new registry for that domain and return it. Modifies the registries atom in the service context to add the new registry

GraphiteRegistryReporterConfig clj

GraphiteReporterConfig clj

initialize-registries-from-config clj

(initialize-registries-from-config metrics-config)

Inputs: [metrics-config :- MetricsConfig] Returns: #:schema{Any RegistryContext}

Read through the config and create a MetricsRegistry (+ JMX reporter if configured) for every registry mentioned in it. Also create the default registry if not mentioned in the config. Should be called from init of the metrics-service.

initialize-registry-context clj

(initialize-registry-context config domain)

Inputs: [config :- (schema/maybe RegistryConfig) domain :- schema/Keyword] Returns: RegistryContext

Create initial registry context. This will include a MetricsRegistry and a JMX reporter, but not a Graphite reporter.

jmx-reporter clj

(jmx-reporter registry domain)

Inputs: [registry :- MetricRegistry domain :- (schema/maybe schema/Keyword)] Returns: JmxReporter

JmxReporterConfig clj

JolokiaApiConfig clj

lock-registry-settings clj

(lock-registry-settings context)

Inputs: [context :- MetricsServiceContext] Returns: MetricsServiceContext

Switch the can-update-registry-settings? boolean to false to show that it is after the init phase and registry settings can no longer be set.

maybe-add-default-to-config clj

(maybe-add-default-to-config metrics-config)

Inputs: [metrics-config :- MetricsConfig] Returns: MetricsConfig

Add a :default key with an empty map as the value to the registries config if it is not present.

Inputs: [service-context :- MetricsServiceContext]

update-registry-settings clj

(update-registry-settings context domain settings)

Inputs: [context :- MetricsServiceContext domain :- schema/Keyword settings :- DefaultRegistrySettings] Returns: #:schema{Any DefaultRegistrySettings}

Update the registry-settings atom for the given domain. If called again for the same domain, the new settings will be merged in, and lists such as :default-metrics-allowed, will be concat'd together.
