### Pre-check - [x] I am sure that all the content I provide is in English. ### Search before asking - [x] I had searched in the [issues](https://github.com/apache/dubbo/issues?q=is%3Aissue) and found no similar issues. ### Apache Dubbo Component Java SDK (apache/dubbo) ### Dubbo Version Dubbo: 2.7.7 Java: 1.8 i want use MonitorFilter,but i found not have output. output set in here private void logMessageLength(Object result, int bytes) { if (bytes > 0) { if (result instanceof Request) { try { ((RpcInvocation)((Request)result).getData()).setAttachment("input", String.valueOf(bytes)); } catch (Throwable var5) { } } else if (result instanceof Response) { try { ((AppResponse)((Response)result).getResult()).setAttachment("output", String.valueOf(bytes)); } catch (Throwable var4) { } } } } but when after this, output is lose private void decode(Object message) { if (message instanceof Decodeable) { try { ((Decodeable)message).decode(); if (log.isDebugEnabled()) { log.debug("Decode decodeable message " + message.getClass().getName()); } } catch (Throwable var3) { Throwable e = var3; if (log.isWarnEnabled()) { log.warn("Call Decodeable.decode failed: " + e.getMessage(), e); } } } } ### Steps to reproduce this issue use dubbo 2.7.7 then debug can reproduce ,very easy ### What you expected to happen i cat hava output in this code private URL createStatisticsUrl(Invoker<?> invoker, Invocation invocation, Result result, String remoteHost, long start, boolean error) { // ---- service statistics ---- long elapsed = System.currentTimeMillis() - start; // invocation cost int concurrent = getConcurrent(invoker, invocation).get(); // current concurrent count String application = invoker.getUrl().getParameter(APPLICATION_KEY); String service = invoker.getInterface().getName(); // service name String method = RpcUtils.getMethodName(invocation); // method name String group = invoker.getUrl().getParameter(GROUP_KEY); String version = invoker.getUrl().getParameter(VERSION_KEY); int localPort; String remoteKey, remoteValue; if (CONSUMER_SIDE.equals(invoker.getUrl().getParameter(SIDE_KEY))) { // ---- for service consumer ---- localPort = 0; remoteKey = MonitorService.PROVIDER; remoteValue = invoker.getUrl().getAddress(); } else { // ---- for service provider ---- localPort = invoker.getUrl().getPort(); remoteKey = MonitorService.CONSUMER; remoteValue = remoteHost; } String input = "", output = ""; if (invocation.getAttachment(INPUT_KEY) != null) { input = invocation.getAttachment(INPUT_KEY); } if (result != null && result.getAttachment(OUTPUT_KEY) != null) { output = result.getAttachment(OUTPUT_KEY); } return new URL(COUNT_PROTOCOL, NetUtils.getLocalHost(), localPort, service + PATH_SEPARATOR + method, MonitorService.APPLICATION, application, MonitorService.INTERFACE, service, MonitorService.METHOD, method, remoteKey, remoteValue, error ? MonitorService.FAILURE : MonitorService.SUCCESS, "1", MonitorService.ELAPSED, String.valueOf(elapsed), MonitorService.CONCURRENT, String.valueOf(concurrent), INPUT_KEY, input, OUTPUT_KEY, output, GROUP_KEY, group, VERSION_KEY, version); } ### Anything else _No response_ ### Are you willing to submit a pull request to fix on your own? - [ ] Yes I am willing to submit a pull request on my own! ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
