thanks, our monitor is getting the result from the tomcat manager page which provides the busy threads count and totol threads count, i'm not sure if tomcat manager treat the keepAlived thread as free. if the tomcat manager treat the keepAlived thread as free, seems we can't kown what's the concurrent work threads, when we need to add the max threads or add more tomcat servers. shall we use current total threads to judge this? if it reaches to max configured threads, need to add max threads or add tomcat servers? -- 从myMail的Android专用app所发送 星期三, 18 一月 2017, 06:08下午 +08:00 发件人 André Warnier (tomcat) a...@ice-sa.com :
