JPDH — Windows Performance Data Helper for Java Maven Central License

JPDH is a Java library to retrieve performance counter values on Microsoft Windows using the PDH (Performance Data Helper) API and some additional features built on top of it.

Installation

Manually

Add jpdh.jar to your CLASSPATH.

With Maven

<dependency>
  <groupId>com.arkanosis</groupId>
  <artifactId>jpdh</artifactId>
  <version>1.1.4</version>
</dependency>

With Gradle

compile("com.arkanosis:jpdh:1.1.4")

Usage

import com.arkanosis.jpdh.Counter;
import com.arkanosis.jpdh.JPDH;
import com.arkanosis.jpdh.Query;

try (Query query = JPDH.openQuery()) {
	Counter diskCounter = query.addCounter("\\PhysicalDisk(_Total)\\Disk Read Bytes/sec");
	Counter cpuCounter = query.addCounter("\\PID(8584)\\% User Time");
	query.collectData();
	System.out.println(diskCounter.getDoubleValue());
	System.out.println(cpuCounter.getIntegerValue());
	query.removeCounter(diskCounter);
}

Any valid PDH counter path can be used, and additional counter path using the non-PDH “PID” object can be used as well:

\\computer\Process(parent/instance#index)\counter
\\computer\PID(pid)\counter

Build

Run make.

If you don't have a POSIX environment under Windows, you might want to have a look at MSYS2.

Additionally, you may run the test suite using make runtest.

History

  • 2019-09-20: version 1.1.4 — Bugfix release. Counters based on the virtual “PID” object sometimes couldn't be initialized while lots of processes were started of stopped.
  • 2017-09-14: version 1.1.3 — Bugfix release. The virtual “PID” object didn't work on localized (eg. German) versions of Windows.
  • 2016-06-08: version 1.1.2 — Bugfix release. Calling Query.removeCounter(counter) on counters associated with dead processes was throwing an exception.
  • 2016-06-01: version 1.1.1 — Bugfix release. Calling Query.removeCounter(counter) on counters associated with dead processes was throwing an exception.
  • 2016-04-19: version 1.1 — Additional “PID” object which maps to the “Process” object for the right process instance and index
  • 2016-04-01: version 1.0 — Initial version exposing PDH features in Java
