What errors may be logged and where?

The default error log file is ZEUSHOME/web/log/errors.

You can override this default setting with the global.cfg tunable "errlog"; see the configuration settings FAQ entry.You can also configure different error log locations for each virtual serveras part of the "Monitoring: Error Handling" configuration.

The error message strings that Zeus Web Server reports in $ZEUSHOME/web/log/errors are built dynamically and contain the following structure:

 a. [<date>] <severity>:<message> b. [<date>] <severity>:<component>:<message>  c. [<date>] <severity>:<virtualserver>:<message> d. [<date>] <severity>:<virtualserver>:<component>:<message> e. "other text"

Type e. "other text" doesn't actually come from the Web Server,these are the sort of messages that come from cgi scripts, forexample.

The <severity> is one of the following:

"FATAL", "SERIOUS", "DOS", "SSL", "WARN" or "INFO"

"DOS" and "SSL" messages will only be logged if the Service Protection or SSL modules are enabled.

For a description of the other categories, please see Section 2.8 'Logging' in the Zeus Web Server User Guide.

<virtualserver> is the name of the virtual server, where applicable<component> is the name of the ZWS component, for example 'zeus.isapi', 'Statd', 'CGId' etc.

It is important to appreciate that some error messages that may appear in the log will have been passed to Zeus Web Server from external sources such as the Operating System, Third Party Product or CGI etc. Entries in the error logs do not therefore necessarily indicate a problem with Zeus software.
