Site Monitoring

Specifying a customised log format

Scheduler - Format Specification

In order for Site Vigil to work with a wide variety of log file formats it needs to have a flexible specification of how the log records are formatted. This dialog offers a wide range of facilities for specifying a format. If this proves hard, you can send a log file sample to the Site Vigil Support team who can then generate a new specifier to match the log format.

In order for Site Vigil to monitor log files it needs at least the date and time, client IP address, status code, requested page and referrer to be specified in each log record. Most servers provide a subset of the Log file fields available for each client request.

Each format must give a unique Log Format Name, SiteVigil recognises embedded information in some log files telling it the format of the log. You can instruct SiteVigil to use this format if it finds it rather than the configured specification,

The main display area shows a sample log file line fetched from the Web Server and the fields as understood by SiteVigil. The primary way that log files differ is that they may use different characters to separate fields in each record, select the appropriate one from the list. The remaining dialog entries operate on individual fields. You can change the properties of the currently selected field. If you are adding a new field press Add Field. If the field is correctly specified but in the wrong place use the Move Up and Move Down to move it within the record.

Some formats add extra characters before or after fields, you can tell SiteVigil to ignore these by specifying an Ignore Initial or Final Character field value. Strings may appear in quotation marks (") in the log file so you need to be careful to select the correct string format option. Date and Time specifiers offer even more options and a special dialog is provided to modify this setting using the Edit button.
