Zoberme si ako pr\u00edklad metriku pre zmenu vo\u013en\u00e9ho miesta na disku virtu\u00e1lneho stroja. Napr\u00edklad dostaneme \u010d\u00edslo 90, a toto \u010d\u00edslo znamen\u00e1 percent\u00e1, to znamen\u00e1, \u017ee objem vo\u013en\u00e9ho miesta na disku je 90%.

Po prv\u00e9, mer\u00e1me hodnotu nie\u010doho, aby sme n\u00e1sledne pou\u017eili v\u00fdsledok merania. <\/p>\n

\"David

Microsoft urobil proces z\u00edskavania metr\u00edk ve\u013emi jednoduch\u00fdm, ale mus\u00edte si sami zabezpe\u010di\u0165 ich zber. Tieto metriky sa uchov\u00e1vaj\u00fa len 41 dn\u00ed a na 42. de\u0148 zanikaj\u00fa. Preto v z\u00e1vislosti od vlastnost\u00ed v\u00e1\u0161ho extern\u00e9ho alebo intern\u00e9ho zariadenia by ste sa mali postara\u0165 o to, ako uchov\u00e1va\u0165 metriky dlh\u0161ie ako 41 dn\u00ed \u2014 vo forme logov, protokolov at\u010f.

A\u017e po tom, \u010do z\u00edskate hodnoty metr\u00edk, interpretujete ich a zbierate ich, budete m\u00f4c\u0165 vytvori\u0165 SLA \u2013 dohodu o \u00farovni poskytovania slu\u017eby.

Metrika m\u00f4\u017ee mera\u0165 po\u010det tiketov \u2014 napr\u00edklad z\u00edskavate 5 tiketov denne, a v tomto pr\u00edpade ukazuje r\u00fdchlos\u0165 reakcie na po\u017eiadavky pou\u017e\u00edvate\u013eov a r\u00fdchlos\u0165 odstra\u0148ovania probl\u00e9mov.
