Dumpling plugin for Jenkins brings Dumpling DSL capabilities into Jenkins

This plugin make Dumpling DSL available for:

  • Groovy scripts all over Jenkins
  • Other plugins

Capturing current Jenkins thread state should be as easy as calling Dumpling.runtime in script console/scriptler/groovy plugin step to investigate or periodically monitor Jenkins threads. See Dumpling DSL tutorial for more information on how to use dumpling. Note that the DSL differs a bit in Jenkins Groovy interpreters as the ability to configure is a bit limited.

Useful scripts

General jstack-like threadddump:

println D.runtime.threads
// Or before 2.2
println Dumpling.runtime.threads

Detailed thread blockage report:

D.runtime.query(D.query.blockingTree().showStackTraces())
// Or before 2.2
import com.github.olivergondza.dumpling.query.*;

println Dumpling.runtime.query(new BlockingTree().showStackTraces());

Brief blockage report focused on HTTP handling threads:

import com.github.olivergondza.dumpling.query.*;

println Dumpling.runtime.threads.grep { it.name =~ /^Handling / }.query(new BlockingTree())

Capture threaddump of different java process (most likely on agent):

// List processes
println 'jps -l'.execute().text

// Print runtime
D.load.process(PID_NUMBER)
// Or before 2.2
new com.github.olivergondza.dumpling.factory.PidRuntimeFactory().fromProcess(PID_NUMBER);
