Filters attached to an appender determine whether the containing
appender sees events. For example, the following configuration snipped
will cause appender A to only see events of level WARN.
<appender name="A" class="...."/>
<filter class="ch.qos.logback.classic.filter.LevelFilter">
<level>WARN</level>
<onMatch>NEUTRAL</onMatch>
<onMismatch>DENY</onMismatch>
</filter>
</appender>
Note that ch.qos.logback.classic.filter.LevelFilter is an equality
filter checking on Level.WARN. Appender A will never see events of level
TRACE, DEBUG, INFO and ERROR.
Triggering of emails is determined by the evaluator [1] assigned to
SMTPAppender. For an event to trigger a message, it must pass through
all the filters attached to SMTPAppender and have the evaluator return true.

Hi there,
I'm having an issue with using multiple filters as you had outlined in a
previous post:
<appender name="SQL_TRANSACTION_DELAY_EMAIL"
class="ch.qos.logback.classic.net.SMTPAppender">
<filter class="ch.qos.logback.classic.filter.LevelFilter">
<level>WARN</level>
<onMatch>NEUTRAL</onMatch>
<onMismatch>DENY</onMismatch>
</filter>
<filter
class="com.annadaletech.taxfree.kioskapp.util.SQLTransactionDelayFilter">
<transactionDelayText>running time
(millis)</transactionDelayText>
</filter>
...
</appender>
The first filter is looking for any log entry marked as [WARN ] and the
second checks this message for my own user defined value and whether or not
the email needs to be sent. However, though the second filter code is being
accessed, the email is not passed from an ACCEPT filterReply.
I've also read somewhere that apparently the SMTPAppender wont send an email
unless its catching an ERROR message. If so, how can I alter this?
Your thoughts appreciated,
Ray.
