Using the Generic Text Filter in an event handler
The Generic Text Filter uses the glibc regex library for values with operators (~,!~), using the POSIX standard.

For example,

To create an event handler using the Generic Text Filter to match raw log data:
- Go to Log View, and select a log type.
- In the toolbar, click Tools > Display Raw.

- In the Generic Text Filter box, paste the text you copied or type the text you want. Ensure you use the raw log field names, for example,

- Configure other settings as required and click OK. For a description of the fields, see Creating a custom event handler.
