Comment obtenir CPU, RAM et Réseau-Utilisation d'une application Java7
J'ai trouvé cet article plus ancien comment-pour-suivre-les-ordinateurs-processeur-mémoire-et-disque-utilisation-en-java et wated de demander, s'il y a quelque chose de nouveau dans java 7. Je veux obtenir périodiquement l'utilisation actuelle du PROCESSEUR, de la RAM et de netzwork de mon application. Il doit fonctionner pour linux (mac) et Windows. Les données ne doivent pas être extrêmement détaillées, 3 valeurs suffiraient (cpu: 10%, Ram 4%, Réseau 40%). Ce serait cool si les données sont juste pour l'application et non l'ensemble du système d'exploitation, mais cela fonctionnerait aussi.
Merci pour l'aide

Répondre à ma propre question ;P un code que j'ai écrit...

Pourquoi ne pouvez-vous pas simplement utiliser comme ci-dessous,
try {
for (String ni : sigar.getNetInterfaceList()) {
NetInterfaceStat netStat = sigar.getNetInterfaceStat(ni);
total+=netStat.getRxBytes();
}
} catch (SigarException e) {
e.printStackTrace();
}
Quelle est la différence???

J'utiliserais la bibliothèque java Metrics: http://metrics.codahale.com/
Il est livré avec l'intégration Sigar: https://github.com/cb372/metrics-sigar

Peu de choses ont changé depuis, sauf si cela a été fait par un autre groupe. voici quelques-uns des changements importants qui ont été inclus dans Java 7 SE. Malheureusement, aucun d'entre eux n'est ce que vous recherchez.

Javamelody que j'ai utilisé auparavant est assez simple et j'ai pu le faire fonctionner en peu de temps temps
