Measures reported by TomcatConnectorTest
The Http connector in the Tomcat Web server, represents a Connector component that supports the HTTP/1.1 protocol, which enables Catalina to function as a stand-alone web server, besides its ability to execute servlets and JSP pages. A particular instance of this component listens for connections on a specific TCP port number on the server to perform request processing and response creation. You can have one or more such Connectors configured to form a part of a single Service with each forwarding service to the associated engine.
The TomcatConnectorTest observes the data traffic on each connector and measures the connector's processing ability.

Description |
Measurement
Unit |
Interpretation |
| Request_count |
Indicates the number of requests received by the connector, since the last measurement period
|
Number
|
|
| Avg_processing_time |
Indicates the average time taken by the connector to process requests
|
Secs
|
This measure is a clear indicator of the Connector health. Ideally, this value should be low. A very high value indicates processing bottlenecks.
|
| Data_sent |
Reports the data that was sent by the connector since the last measurement period
|
KB
|
|
| Data_received |
Reports the data that was received by the connector since the last measurement period
|
KB
|
Both the Data_sent and Data_received measures together indicate the load on the Tomcat server.
|
| Error_count |
Indicates the number of errors that were reported by the connector since the last measurement period
|
Number
|
Ideally, the value of this measure should be 0. A non-zero value warrants further investigation.
