Relay Server logging and log administration

The Relay Server log file displays the following types of messages:

Information Basic information about your current session.
Warning Warning messages about actions that have occurred.
Error Error messages about actions that have failed.

The default log file name and directory for Windows is %temp%\ias_relay_server_host.log. To change the log file name, use the rshost -o filename option.

In addition, Relay Server logging supports the following features:

The Relay Server and Outbound Enabler logs report timestamps in millisecond resolution.

Timestamps are reported in RFC 822 local differential format (+/- hhmm).
When the Relay Server and Outbound Enabler handle HTTP requests that carry the SAP Passport header, the Relay Server and the Outbound Enabler increase the request handling verbosity level to match the trace level requirement contained in the Passport and also add a suffix to the associated log lines to list the key information of the Passport.

Verbosity

You can set Relay Server log verbosity to the following levels:

0 Log errors only. Use this logging level for deployment. This is the default.
1 Request logging. Summaries of HTTP requests are written to the log file in an abbreviated format.
2 Request logging. Provides a more detailed view of HTTP requests.
3 or higher Detailed logging. Used primarily for Technical Support.

Errors are displayed regardless of the log level specified, and warnings are displayed if the log level is 1 or higher.
