I see a problem and wanted to do a quick heads up before double checking:
When looking at the MBeans via the jmxproxy in the manager webapp,
especially the
Catalina:type=RequestProcessor,worker="http-nio-<PORT>",name=HttpRequest<NUM>, version 9.0.66 misses lots of attributes we previously made available:
bytesReceived
bytesSent
errorCount
lastRequestProcessingTime
maxRequestUri
maxTime
processingTime
requestCount
stage
workerThreadName
The attributes that are still available are:
contentLength
currentQueryString
currentUri
globalProcessor
method
modelerType
Name
peerAddr
protocol
remoteAddr
remoteAddrForwarded
requestBytesReceived
requestBytesSent
requestProcessingTime
rpName
serverPort
virtualHost
It seems the recent 10.0 and 10.1 suffer from the same problem.
I noticed this during testing, because I use tooling that is based on
parts of this MBean info.
Best regards,
Rainer
The logs show (just an example, one such block for any missing attribute):
