Locust4j Slave fails to send heartbeat to master #15

Closed ArunaGit2020 closed 4 years ago

ArunaGit2020 commented 4 years ago

Hi, Thanks for nice useful library!

OS: MacOS-Mojave, Openstack - CentOS7 Java: OpenJDK11, OpenJDK8

I am trying to run Locust4j as per this link using Java : https://www.blazemeter.com/blog/locust-performance-testing-using-java-and-kotlin/

Once I run the main class, I see this log statement in master log: INFO/locust.runners: Client '' reported as ready. Currently 1 clients ready to swarm.

And, java main class log says: DEBUG com.github.myzhan.locust4j.rpc.ZeromqClient - Locust4j is connected to master(127.0.0.1:5557)

However, immediately within second, I keep getting this error in master log :

I tried with JDK11, JDK8 and in Mac & Openstack as well. Also, tried running it from Eclipse IDE and through terminal as mentioned in the above BlazeMeter url. No luck. What might be going wrong?

Thanks!

I see there is a PR: https://github.com/myzhan/locust4j/pull/14 open to address this "current_cpu_usage" . So, I am closing this issue assuming that would be merged soon.

Yes, 1.0.9 has been released. It may take a while to sync to the maven central.

Thank you! I can see that reflected in maven.
