README

        
This library provides convenient access to JVM debugging information.

- `ThreadInfo.format` Get a `String` output as if you had run

  `jcmd Thread.print -l` on the command-line.

- `Memory.dumpHeap` Dump heap to filesystem.

- `Memory.formatNmt` Human-readable formatting of [NMT][1].  Provides

  simpler and more concise formatting than that returned by the JVM.

- `Memory.getNmt` Parsed NMT data (`Nmt` instance), suitable for

  tracking in analytics systems, such as Graphite.

- `Memory.pollNmt` Runs poller thread that periodically logs

  human-readable NMT.

- `Nmt.invoke` If you really must, you can easily get at the

  JVM-formatted human-readable NMT summary.
