Dear Skywalking Dev, I found a lot of "trace segment has been abandoned, cause by buffer is full" logs in my Java services with Skywalking 6.6.0 agent enabled. DEBUG 2020-01-06 20:43:17:699 http-nio-0.0.0.0-9090-exec-154 TraceSegmentServiceClient : One trace segment has been abandoned, cause by buffer is full.
And some "xxx trace segments have been abandoned, cause by no available channel" logs were found also. 2020-01-06 21:37:53:716 DataCarrier.DEFAULT.Consumser.0.Thread TraceSegmentServiceClient : 237 trace segments have been abandoned, cause by no available channel. I checked the source code & documentation found that the default buffer setting is 5(channel_size)*300(buffer_size) and it seems that this default setting is not enough for productive environment of heavy load system. To avoid the trace segment abandon, is that OK to just increase the buffer setting (e.g. to 10* 3000) ? How to estimate the memory(in MB) for the buffer setting so that I can evaluate the memory footprint for segments buffer? Thanks & Best Regards Xiaochao Zhang(James) DI SW CAS MP EMK DO-CHN No.7, Xixin Avenue, Chengdu High-Tech Zone Chengdu, China 611731 Email: [email protected] <mailto:[email protected]>
