Total metrics are broken in Kafka streams 2.0.0

2018-08-01 Thread Sam Lendle
Is this a known issue? If not I can create a JIRA. For example, here’s a screenshot of the process-total metric for one processor node and task under stream-processor-node-metrics. Processor-total goes down over time when it shouldn’t. Same thing for total metrics under stream-metrics, stream-*

r those tasks has been cleaned. Is this also fixed, or a separate issue? This may be an issue that is not yet resolved, I'd need to double check. At the mean time, could you create a JIRA for it? Guozhang On Thu, Jul 12, 2018 at 4:04 PM,

Kafka Streams processor node metrics process rate with multiple stream threads

2018-07-11 Thread Sam Lendle
Hello! Using kafka-streams 1.1.0, I noticed when I sum the process rate metric for a given processor node, the rate is many times higher than the number of incoming messages. Digging further, it looks like the rate metric associated with each thread in a given application instance is always the

2018-06-28 Thread Sam Lendle
Please correct me if I’m wrong, but I’m under the impression that the task_id in streams metrics is formatted as _, and topicGroupId corresponds to a particular subtopology in the streams topology. I assume that’s true for the rest of this message. I have a streams app with multiple sub topolog

Kafka Streams Session store fetch latency very high with caching turned on

2018-06-22 Thread Sam Lendle
I am using a session store in a kafka streams application. With caching turned on, average fetch latency was very high, about 200 ms after running for about 1 hour. With caching turned off, it was about 100 μs. We seem to be running fine without caching, but I am very curious as to why caching p

Some Total and Rate metrics are not consistent

I’m trying to use the total metrics introduced in KIP-187 (https://cwiki.apache.org/confluence/display/KAFKA/KIP-187+-+Add+cumulative+count+metric+for+all+Kafka+rate+metrics) For some metrics, the total and rates are not consistent. In particular, for stream-processor-node-metrics, I’m seeing
