List of metrics for Relay Server Farm resources

Metric Name	Description
Active Requests	Shows total number of concurrent requests
Average Back End Server Processing Time	Measures the average time it takes for the backend server to process an HTTP request.
Average Request Completion Time	Measures the average time after a response is sent to the client that the Relay Server waits for a backend connection to close.
Average Request Time	Measures the average time the Relay Server waits to receive the entire HTTP request from the client.
Average Request-Response Cycle Time	Measures the average time the Relay Server takes to process a request and receive a response.
Average Response Time	Measures the average time it takes the Relay Server to receive the entire HTTP response from the backend server.
Channel Timeout	The maximum latency for the Relay Server to detect a blackout of a backend service.
CPU Usage	Measures the average percentage of CPU time used by the Relay Server.
Down Channel Bytes	Shows the total number of bytes coming down from the outbound enabler to the backend server extension during the last collection period.
Error Count	Shows the total number of errors that occurred during the last collection period. This count includes the error count of the children.
Farm Status	Shows current status of the Relay Server Farm: 0 The Relay Server Farm is enabled and it can provide service normally. 1 The Relay Server Farm is disabled so that the outbound enabler cannot connect and provide service. The clients also cannot access this backend farm via Relay Server. 2 The Relay Server Farm is enabled, but some of the outbound enabler(s) are not connected to all Relay Servers in the Relay Server Farm. Quality of service can be affected. 3 The Relay Server Farm is enabled but none of the backend server is connected and so no client will be able to access this backend farm.
Free Disk Space For Log File	Shows the disk space available for the Relay Server Farm log file.
Host	Shows the name of the computer running the Relay Server Farm.
Operating System Version	Shows the operating system on which the Relay Server software is running, including build numbers and service packs.
Peak Active Requests	Shows the maximum number of concurrent requests since the Relay Server started.
Peak Shared Memory Usage	Shows the maximum usage of shared memory of the Relay Server since the Relay Server started.
Processor Architecture	Shows type of processor on which the Relay Server farm is running.
Relay Server Start Time	Shows the start up time for the Relay Server. For backend servers, shows the time the outbound enabler is connected to the backend server extension.
Relay Server Status	Shows the status of the Relay Server.
Relay Server Version	Shows the version of the Relay Server software being run.
Request Bytes	Shows the total number of bytes from HTTP requests coming up from the client to the client extension.
Requests Completed	Shows the total number of finished request-response cycles.
Response Bytes	Shows the total number of bytes in HTTP responses coming down from the client extension to the client.
Sessions Created	Shows the total number of new HTTP sessions created.
Shared Memory Limit	Shows the total shared memory available to the Relay Server.
Unavailable Since	Shows the time since the resource became unavailable.
Up Channel Bytes	Shows the total number of bytes going up from the backend server extension to the outbound enabler.
Web Server Version	Shows the version of the Web Server software being run.
