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></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>If anyone has any suggestions, I would greatly appreciate.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thanks,<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><b><span style='font-size:9.0pt;font-family:"Arial","sans-serif";color:#0F243E'>Bob DeRemer<o:p></o:p></span></b></p><p class=MsoNormal><b><span style='font-size:8.0pt;font-family:"Arial","sans-serif";color:#0F243E'>Senior Director, Architecture and Development<o:p></o:p></span></b></p><p class=MsoNormal><span style='font-family:"Arial","sans-serif"'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:8.0pt;font-family:"Arial","sans-serif";color:#0F243E'><a href="http://www.burningskysoftware.com/"><span style='color:blue'>http://www.burningskysoftware.com</span></a><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:8.0pt;font-family:"Arial","sans-serif";color:#0F243E'>O: 717.505.7923<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:8.0pt;font-family:"Arial","sans-serif";color:#0F243E'>M: 717.881.3986<o:p></o:p></span></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
