How can I check my Streaming API limits and usage?

Question

The new Salesforce integration relies on the Streaming API. If the daily limits of the streaming API are exceeded, Salesforce returns a rate-limit error to our integration. In this case, our integration will deactivate the Data Sync to avoid making this rate-limitation problem worse.

How can I check on API usage and the daily rate limit to help avoid this deactivation?
