Instance Method Details

#get_latencies ⇒ Hash

Return relevant latencies for this checker. This could be the latencies of each Sidekiq queue, or web latencies, etc. If this is a pool usage checker only, return {}.

Returns:

• (Hash) —

  Key is the queue name (or some other value); value is the latency in seconds.

Raises:

• (NotImplementedError)

def get_latencies = raise NotImplementedError

#get_pool_usage ⇒ nil, Float

Return the pool usage for this checker. Values should be between 0 and 1, with values over 1 meaning a backlog. If this is a latency checker only, or there is not enough information to report on pool usage, return nil.

Returns:

• (nil, Float)
