Custom Log Formats


When Angelfish processes a log file, it needs know the contents and position of each field in the log. Angelfish gets this information from the log format assigned to each Datasource.

If your log file format doesn't match one of the predefined log formats, you'll need to create a custom log format. The Log Format utility can be accessed by Angelfish admins in Configure - Global - Log Formats.

Creating a Custom Log Format

Log formats are space delimited, with specific fields surrounded by quotes. Use the dropdown to select a field and click the arrow to move it into the log format box.

Once you create your custom log format, copy and paste a single log line into the "Test Log Format" field and click the Test button. If the utility is able to successfully parse the log line and the data & fields match, then the format is correct.

Here's a sample log line: - [23/Oct/2012:12:02:03 -0500] "GET /blog/google-analytics-vs-log-files HTTP/1.1" 200 186 "" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_2) AppleWebKit/536.26.14 (KHTML, like Gecko) Version/6.0.1 Safari/536.26.14" "JSESSIONID=a1eea565c4b83f8ba94c8ba2a285c8fb" 23Q12 "f5 failover"


Here's an example of a custom log format that will parse the above line. Please note how the quote-encapsulated fields in the log line match the quote-encapsulated fields in the custom log format:

%a %h %* %t "%r" %s %b "%R" "%ua" "%c" %* "%*"
