Sorry I lied, The following do not update: ProduceRequestsPerSecond FetchRequestsPerSecond AvgProduceRequestMs MaxProduceRequestMs AvgFetchRequestMs MaxFetchRequestMs BytesReadPerSecond BytesWrittenPerSecond
These stats do update with new values: NumFetchRequests NumProduceRequests TotalBytesRead TotalFetchRequestMs TotalProduceRequestMs -----Original Message----- From: Xuyen On Sent: Tuesday, May 20, 2014 11:30 AM To: 'users@kafka.apache.org' Subject: RE: SocketServerStats not reporting bytes written or read To be more clear, 1. I am using jmxtrans to get the data not jmstats. Sorry about the misspelling. 2. When I say the stats zero out, I mean that I am not able to get new values when I refresh with a new query from jmxtrans or jconsole. This only happens for the kafka.SocketServerStats:BytesWrittenPerSecond and kafka.SocketServerStats:BytesReadPerSecond stats. The other stats seem to update fine. Any ideas why this might be? -----Original Message----- From: Xuyen On Sent: Tuesday, May 20, 2014 11:24 AM To: users@kafka.apache.org Subject: RE: SocketServerStats not reporting bytes written or read I checked the stats with jconsole and it confirms the reading I've been getting with jmxtrans so the problem is with the jmx beans themselves I think. The stats just came back to normal again and I don't know why. I haven't made any changes to the kafka brokers. -----Original Message----- From: Jun Rao [mailto:jun...@gmail.com] Sent: Monday, May 19, 2014 9:45 PM To: users@kafka.apache.org Subject: Re: SocketServerStats not reporting bytes written or read Is the problem with the jmx beans themselves or jmxstats?
