Research direction

No implementation file or test is named. Start by locating any existing Loggregator or nozzle integration in the Java client and compare it with the jmx-consumer-based client described. Done would require verified Loggregator 2.x support for metric extraction and a resolution or explanation for the reported direct-memory failure.

Description

doppler enhancement triaged

Does this Java client include support for Loggregator 2.x? I'm interested in extracting metrics through the nozzle.

Currently using a client based off of your jmx-consumer project and have seen customers run into a memory issue after a few days of running.

Caused by: io.netty.util.internal.OutOfDirectMemoryError: failed to allocate 16777216 byte(s) of direct memory (used: 1845494055, max: 1860698112)
    at io.netty.util.internal.PlatformDependent.incrementMemoryCounter(PlatformDependent.java:640)
    at io.netty.util.internal.PlatformDependent.allocateDirectNoCleaner(PlatformDependent.java:594)
    at io.netty.buffer.PoolArena$DirectArena.allocateDirect(PoolArena.java:764)
    at io.netty.buffer.PoolArena$DirectArena.newChunk(PoolArena.java:740)
    at io.netty.buffer.PoolArena.allocateNormal(PoolArena.java:244)

Any insight would be appreciated.

Thanks,
Aditya
