Web Response Time tracking is enabled but no data is displayed

The problem: Web Response Time tracking is enabled but no data is displayed in the workspaces. The agent logs report an error similar to the following example:
(4C875A62.0037-5:analyzerlogadapter.cpp,59,"log")
(../../../src/Core/Analyzer/WRTTracker.cpp,450) 
TTAPI Initialization completed with error code [21]

The solution: This problem might occur if Transaction Collector connection string is not specified correctly in the Data Collection section of the Web Response Time agent configuration. For example, this error can occur if you neglect to preface the connection string with tcp:.

See the appendix, Transport address format in the Transaction Tracking API User's Guide for the correct format, and correct the Web Response Time agent configuration as needed. Then restart the agent and verify that the connection initializes successfully.
