It extends AppenderBase<ILoggingEvent> like the docs say, but for some reason, any logging statements where we use the logback parameter substitution (i.e. “message with parameter {}”, param1), there is no substitution. We have our custom appender AND a FileAppender. The fileappender has the parameter substituted, but the custom one does not. <o:p></o:p></div><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 11pt; font-family: Calibri, sans-serif; "><o:p> </o:p></div><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 11pt; font-family: Calibri, sans-serif; ">If anyone has any suggestions, I would greatly appreciate.<o:p></o:p></div><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 11pt; font-family: Calibri, sans-serif; "><o:p> </o:p></div><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 11pt; font-family: Calibri, sans-serif; ">Thanks,<o:p></o:p></div><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 11pt; font-family: Calibri, sans-serif; "><o:p> </o:p></div><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 11pt; font-family: Calibri, sans-serif; "><b><span style="font-size: 9pt; font-family: Arial, sans-serif; color: rgb(15, 36, 62); ">Bob DeRemer<o:p></o:p></span></b></div><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 11pt; font-family: Calibri, sans-serif; "><b><span style="font-size: 8pt; font-family: Arial, sans-serif; color: rgb(15, 36, 62); ">Senior Director, Architecture and Development<o:p></o:p></span></b></div><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 11pt; font-family: Calibri, sans-serif; "><span style="font-family: Arial, sans-serif; "><o:p> </o:p></span></div><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 11pt; font-family: Calibri, sans-serif; "><span style="font-size: 8pt; font-family: Arial, sans-serif; color: rgb(15, 36, 62); "><a href="http://www.burningskysoftware.com/" style="color: blue; text-decoration: underline; "><span style="color: blue; ">http://www.burningskysoftware.com</span></a><o:p></o:p></span></div><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 11pt; font-family: Calibri, sans-serif; "><span style="font-size: 8pt; font-family: Arial, sans-serif; color: rgb(15, 36, 62); ">O: 717.505.7923<o:p></o:p></span></div><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 11pt; font-family: Calibri, sans-serif; "><span style="font-size: 8pt; font-family: Arial, sans-serif; color: rgb(15, 36, 62); ">M: 717.881.3986<o:p></o:p></span></div><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 11pt; font-family: Calibri, sans-serif; "><o:p> </o:p></div></div>_______________________________________________<br>Logback-user mailing list<br><a href="mailto:Logback-user@qos.ch" style="color: blue; text-decoration: underline; ">Logback-user@qos.ch</a><br><a href="http://qos.ch/mailman/listinfo/logback-user" style="color: blue; text-decoration: underline; ">http://qos.ch/mailman/listinfo/logback-user</a><br></div></span></blockquote></div><br></div></body></html>
