Reporting

tagged :: (MonadReader env m, HasStatsClient env) => [(Text, Text)] -> m a -> m a

Include the given tags on all metrics emitted from a block

increment :: (MonadUnliftIO m, MonadReader env m, HasStatsClient env) => Text -> m ()

Synonym for counter 1

counter :: (MonadUnliftIO m, MonadReader env m, HasStatsClient env) => Text -> Int -> m ()

gauge :: (MonadUnliftIO m, MonadReader env m, HasStatsClient env) => Text -> Double -> m ()

histogram :: (MonadUnliftIO m, MonadReader env m, HasStatsClient env, ToMetricValue n) => Text -> n -> m ()

Emit an elapsed duration (which Datadog calls a histogram)

The ToMetricValue constraint can be satisfied by most numeric types and is assumed to be seconds.

histogramSince :: (MonadUnliftIO m, MonadReader env m, HasStatsClient env) => Text -> UTCTime -> m ()

histogramSinceMs :: (MonadUnliftIO m, MonadReader env m, HasStatsClient env) => Text -> UTCTime -> m ()
