---------------------------------------------------------
Yes, I want create a custom Alarm Appender and a custom Alarm Filter. The
filter define more attributes, all the filter attributes will be used by the
layout. LogEvent contextData is readonly, no any place can pass the attributes
between log4j2 components. Like the config above, we will generate the follow
log message.
when match the filter
<Alarm>
<resolver>[email protected]</resolver>
<subject>title1</subject>
<priority>1</priority>
<expression>^hello.*</expression>
</Alarm>
the follow message will be log to file
{[email protected]|mailto:[email protected]] subject=title1
priority=1 message=log massage }
when match
<Alarm>
<resolver>[email protected]</resolver>
<subject>title2</subject>
<priority>1</priority>
<logLevel>error</logLevel>
</Alarm>
the follow message will be log to file
{[email protected]|mailto:[email protected]] subject=title2
priority=1 message=log massage }
So, I hope that LogEvent has such a feature that users can pass data between
log4j2 components.
thanks

> We standardize the alarm base on log4j2, there are trigger rules and alarm
> handle team on the filter, these information will log to file, then our log
> analysis module will send mail to the team with the filter configuration. but
> this information can not be passed to the layout module, so I want to add an
> attribute to pass information between log4j2 components.

> <AlarmAppender name="alarm">
> <Filters>
