ThreadDumper

The ThreadDumper plugin starts dumping stack-traces at the given interval.

This version of the ThreadDumper is for Manatee v2.0.

Plugin.start(
    "ThreadDumper",
    "<version>",
    {
        maxDepth: 3,                    // How deep stacktraces to generate, optional
        dumpIntervalInSeconds: 10,      // How often to dump, optional
        dumpAsJson: false,              // Dump as JSON, optional 
        onlyDumpIfCpuExceeds: 0.2       // Only dump if CPU exceeds this threshold (here 20%, single core), optional
    }
);

Module

The ThreadDumper module can be used to dump stack-traces at any time.

var dumper = Module.load("ThreadDumper", "<version-here>>");
var stackTraces = dumper.dump();º

You can also use it to record cpu usage:

var dumper = Module.load("ThreadDumper", "<version-here>");
var usage = dumper.cpu(10); // 10 seconds recording

Usage is an object with the following properties:

• total: total cpu usage
• user: user cpu usage
• kernel: system/privileged/kernel cpu usage
