Configuring logging for other server components

About this task
Other server component errors can be found in the log files available under the profile directory for each profile. Additional errors can be found in these files:
  • IHS log files (../IHS/logs)
  • CM Server startup and shutdown scripts log errors to the CM/logs directory.
  • Rational® ClearQuest® Web or CCRC log files.
The logs provide information about server startup, starting of the RPC servers, and other server information.
A number of configuration parameters related to access, error, and event logging in httpd.conf are grouped under the heading Logging-related directives. You can change any of these parameters:
  • ErrorLog specifies the name of the file where errors are logged. For example, ErrorLog IHS/logs/error.log specifies that errors are logged in the file logs/error.log under the CM Server installation directory.
    Note: Any CM Server log file may be piped to the rotatelogs command, as described in Log rotation and cleanup.
  • LogLevel specifies the type and severity of errors to be logged. For example, LogLevel warn specifies that errors up to and including warnings are logged. Table 1 lists the various log levels in order of decreasing severity. Specifying any of these values logs events of that severity and all lower severities.
    Table 1. CM Server log levels
    LogLevel Messages logged
    emerg Emergency messages about events that may render the server inoperable (Highest severity)
    alert Conditions that should be corrected immediately
    crit Critical conditions such as hardware or system errors
    error All other errors
    warn Warning messages
    notice Conditions that may require special handling
    info Informational messages (lowest severity)
    debug Debugging CM Server
  • LogFormat specifies the format in which events are logged. You can choose a predefined format (for example, common), or you can define your own format. For more information about format tokens and the rules for constructing log file strings, see the documentation for mod_log_config at http://www.apache.org/.
  • CustomLog specifies the name of the file in which CM Server access requests are logged. For example, CustomLog logs/accesserror.log common specifies that access requests are logged in the file logs/accesserror.log under the CM Server installation directory in the common log file format.
