Troubleshooting event table views

Scenario: During event table view creation, when you add a column and select the EVENT class, no slots are available. 

In addition, you see the following message in the session.stdout.<timestamp>.log located at installationDirectory\truesightpserver\logs.

java.lang.IllegalArgumentException: Request header is too large


  1. Go to <installationDirectory>\TrueSightPServer\truesightpserver\modules\tomcat\conf\ and edit the server.xml file.
  2. Locate the following line:

    <Connector connectionTimeout="20000" enableLookups="false" maxHttpHeaderSize="2048" port="80" protocol="HTTP/1.1" redirectPort="443"/>
  3. Change the maxHttpHeaderSize value to 4096:

    <Connector connectionTimeout="20000" enableLookups="false" maxHttpHeaderSize="4096" port="80" protocol="HTTP/1.1" redirectPort="443"/>
  4. Save the file and restart the TrueSight Presentation Server component.
