Host controller using reduced network resources to monitor hosts

摘要

A host controller generates and sends a request for first status information to a host. The host controller receives first status information from the host along with a unique identifier that is associated with the first status information. After a time period, the host controller generates and sends a new request for second status information to the host, the new request including the unique identifier. When second status information and the first status information are associated with the same unique identifier, the host controller receives a response from the host indicating that the second status information is the same as the first status information.

主权项

1. A method comprising:
generating a request for first status information of a host by a processing device executing a host controller; sending the request to the host; receiving the first status information from the host along with a first unique identifier associated with the first status information, the first status information comprising at least one of a network status of the host that indicates network connectivity or a storage status of the host that indicates connectivity to one or more data stores, and the first unique identifier comprising a first signature value generated from the first status information; generating, by the processing device, a new request for second status information of the host, wherein the new request comprises the first unique identifier; sending the new request to the host; and receiving a response from the host indicating that the second status information is the same as the first status information if the second status information and the first status information are associated with the same first unique identifier, wherein the response does not include either the first status information or the second status information.
