Dstatはメジャーなツールですが、プラグインの書き方についてはあまりドキュメントがなかったので、ここに書いてみようと思います。 Hello, World! dstat_hello_world.pyを作って、(CentOSの場合)/usr/share/dstat/にコピーします class dstat_plugin(dstat): def __init__(self): self.name = 'hello_world' self.type = 'f' self.width = 5 self.scale = 1000 self.vars = ('hello', 'world') #def check(self): # # Check anything def extract(self): self.val['hello'] = 1 self.val['world'] = 10000
