Performance Counters

  • Article

The BranchCache performance counters exist under the heading BranchCache. They are useful debugging tools and can be used to monitor BranchCache effectiveness and health. Some performance counters are overloaded and report different measurements on BranchCache clients, content servers and Hosted Cache servers.

Attempted Discoveries

Client

Reports the total number of content discovery attempts sent to peers or the Hosted Cache.

Server

N/A

Hosted cache

Reports the total number of content discovery attempts received from clients.

Average Branch Rate

Client

Reports the average download speed from peers observed by the current node.

Server

N/A

Hosted cache

Reports the average upload speed to clients.

Bytes from Cache

Client

Reports the total number of bytes retrieved from the local cache, peers on the same subnet or from a Hosted Cache.

Server

N/A

Hosted cache

Reports the total number bytes served to client computers.

Bytes from Server

Client

Reports the total number of bytes retrieved from the server (content that could not be found in a cache).

Server

N/A

Hosted cache

Reports the total number bytes downloaded from clients.

Bytes Served

Client

Reports the total number of bytes served by this peer to other peers or to the Hosted Cache server.

Server

N/A

Hosted cache

Reports the total number bytes served to clients.

Cache Complete File Segments

Client

Count of complete, content validated, file segments.

Server

Cache Hit Ratio

Client

Percentage of files retrieved successfully from the Distributed Cache relative original content size.

Cache Partial File Segments

Client

Count of incomplete file segments that need additional data and/or validation.

Server

N/A

Hosted cache

Count of incomplete file segments that need additional data and/or validation.

Discovery Time

Client

Weighted average of time between when a peer discovery query was sent and when the first response arrived.

Client

N/A

Server

N/A

Hosted cache

Count of file segment offers made by peers and accepted by the Hosted Cache. A file segment offer is made by a client computer to the Hosted Cache server after a download from a BranchCache enabled content server.
