------------------------------------
Summary: Adding BurstFilter with Java configuration
Key: LOG4J2-3132
URL: https://issues.apache.org/jira/browse/LOG4J2-3132
Project: Log4j 2
Issue Type: Question
Components: Filters
Affects Versions: 2.14.1
Reporter: Andi Büchler
I'm trying to figure out how to apply a BurstFilter to an Appender and limit
the number of messages to 1 per / second and maxBurst to 1 via Java
configuration but somehow the filter isn't applied and I get an error:
{noformat}
ERROR appender RollbarAppender has no parameter that matches element
BurstFilter{noformat}
So what's the correct way to add filters? This is what I've got:
{code:java}
@Bean
public AppenderComponentBuilder rollbarAppender() {
return configurationBuilder.newAppender("RollbarAppender",
RollbarAppender.ROLLBAR_APPENDER_PLUGIN_NAME)
..
.add(configurationBuilder.newFilter("BurstFilter",
Filter.Result.NEUTRAL, Filter.Result.DENY)
.addAttribute("level", Level.ERROR) // Level of
messages to be filtered. Anything at or below this level will be filtered out
if maxBurst has been exceeded.
.addAttribute("rate", "0.016") // The average
number of events per second to allow.
.addAttribute("maxBurst", "1")); // The maximum
number of events that can occur before events are filtered for exceeding the
average rate. The default is 10 times the rate.
}
{code}
