Configuration
| Name | Type, Usage Constraints, Defaults | Description |
|---|---|---|
| Enable | enum (on|off); optional, basic, conditional; default: on; Supported Pragmas: break | Conditional enable logger, very useful when you only want to see certain requests in the log. Syntax: on|off Sample: Condition:HEADER:Content-Type: application/x-www-form-urlencoded on off This sample enables the logger only for form posts requests. No other requests will be processed. |
| FileName | string; requried, basic; default: none | Define the file name where the logger should write to. |
| RotationPolicy | string; optional, advanced; default: no rotation | Specifies the rotation policy. - size: <size in bytes>:<number of logfiles> For example: "size:10000000:10" means 10 generations of 10MB logfiles - time: <hourly | daily | monthly> Defines when to trigger the logfile rotation: hourly: Rotate every full hour. daily: Rotate at midnight. monthly: Rotate on the first of every month (midnight). |
| LogLine | string; required, basic; default: none | Defines the log line to print. You can use - ENV: <enviroment-variable> HEADER: <header-name> AUTH: <auth-attribute-name>, and others. Be aware that variables must be closed with a ; Sample: "A sample log line with env ENV:my_env; and header HEADER:Content-Type;" If my_env has the value "anything" and Content-Type is "text/html", then this would result in the following log line: "A sample log line with env anything and header text/html" |
