Warning 'Requests over Threshold found' Java SDK

Java SDK
#1

Hi All,

I’m trying to create REST API using quarkus that will call query to couchbase using ReactiveCluster.
I’m using couchbase Java SDK 3.1.0
During performance test, I keep getting below warning:

WARN [com.cou.tracing] (cb-events) [com.couchbase.tracing][OverThresholdRequestsRecordedEvent][10s] Requests over Threshold found: [{“top”:[{“operation_name”:“QueryRequest”,“last_local_address”:“xxx:58144”,“last_remote_address”:“xxx:8093”,“last_dispatch_us”:2697439,“last_operation_id”:“4bf1dbac-23d4-48ec-88fc-f805c7090ebf”,“total_us”:2697826},{“operation_name”:“QueryRequest”,“last_local_address”:“10.130.3.7:58146”,“last_remote_address”:“xxx:8093”,“last_dispatch_us”:2604224,“last_operation_id”:“6881a88e-7ef1-4a58-b4d0-509a50faf9a1”,“total_us”:2604594}],“service”:“query”,“count”:2}]

Is there any idea why I keep getting this warning?
How to solve this?

Thanks

Hi,

This is part of the Observability/Threshold Logging that is included in the SDK - it’s there so you are able to track slow operations that are taking longer than the set threshold, and therefore debug issues.

If you want to reduce the number of these messages then in your CouchbaseEnvironment, you could try increasing the queryThreshold time so that these slow operations do not exceed the threshold, and/or increase the emitInterval duration to reduce how often these messages are displayed. For example:

ClusterEnvironment env = ClusterEnvironment.builder()
        .thresholdRequestTracerConfig(ThresholdRequestTracerConfig.builder()
                .queryThreshold(Duration.ofSeconds(20))
                .emitInterval(Duration.ofMinutes(1)))
        .build();

And then pass this environment into your ReactiveCluster.connect(…) as usual. Details can be found here.

You could also change the log level you are using to INFO or above, however if you still want to see other WARN level messages this would not be appropriate for you.

Hope this helps,
Will
