The Logger utility enables logging for a form and helps you debug form-related issues. one can configure Logger based on the requirements and set the level and category for it for any specific request. Mobile Form has components the Mobile Forms server and Mobile Forms client runtime. You can configure loggers for both the components.
Configuring server logging
Perform the following steps to configure server logging:
-
Apace Sling logging logger configuration option
Apace Sling logging logger configuration option -
Change the Log Level to Debug.
-
Specify name of log file. If you want to generate logs in the Mobile Forms log directory, add ../logs/ before the filename.
-
Change Logger to HTMLFormsPerfLogger. Click Save.
Configuring client logging
There are two ways to enable client-side logging in Mobile Forms:
- Using the request parameter named log
- Using CQ Configuration Manager
Enabling logging using request parameter
Using this method, you can generate logs for a particular request. The name of the request parameter is log. The log URL is as follows:
http://<server>:<port>/lc/content/xfaforms/profiles/test.html?contentRoot=<path of the folder containing form xdp>&template=<name of the xdp>&log=<log configuration>.
The log configuration is made up of the log level and the logger category.

a (xfa): 2 (default level ERROR)
b (xfaView): 6 (user specified TRACE)
a (xfaPerf): 2 (default level ERROR)
Enabling logging using Configuration Manager
If you use Configuration Manager for enabling logging, logs are generated for every render request until the logging is disabled again.

-
Search for and click LC Forms Configurations.

Uploading logs
If the destination is set as 1, all client script log messages are directed to the console. If an administrator requires these logs along with server logs, set destination level to 2. At this level, all logs are collected in a JS object on client side and if form is rendered with default Profile then a Send Logs button appears to the left of Highlight Existing Fields button in toolbar. When user clicks the link, all collected logs are posted to the server and are logged in the configured error log file on the server.
By default, all the information is added to the error.log file at the <livecycle-install-dir>/crx-repository/logs/ directory.
To change the location and name of the log file:
-
Log in to Configuration Manager as an administrator. The default URL of Configuration Manager is http://[Server]:[Port]/lc/system/console/configMgr.
-
Click Apache Sling Logging Logger Configuration. A dialog box appears.
-
Change the Log Level to Debug.
-
Specify path and name of the Log File.
Note:To create logs in the same directory where other log files are kept, specify ../logs/<filename> in the Log Files property.
-
Change the Logger to HTMLFormsPerfLogger and click Save.
