I o v\u00edkendech p\u0159em\u00fd\u0161lel o metrik\u00e1ch: \"A co z toho, \u017ee zm\u011b\u0159\u00edm \u010das? Co mi to p\u0159inese?\"<\/p>\n

Odpov\u00edd\u00e1 to ot\u00e1zce: Co p\u0159inese znalost \u010dasu? \u0158ekn\u011bme, \u017ee dod\u00e1n\u00ed trv\u00e1 5 dn\u00ed. A co d\u00e1l? Je to dobr\u00e9 nebo \u0161patn\u00e9? I kdyby to bylo \u0161patn\u00e9, mus\u00edme n\u011bjak zkr\u00e1tit tento \u010das. Ale jak?
\nTyto my\u0161lenky mu nedaly sp\u00e1t, ale \u0159e\u0161en\u00ed nep\u0159ich\u00e1zelo.<\/p>\n

Ivan ch\u00e1pal, \u017ee se dostal k j\u00e1dru probl\u00e9mu. Bezpo\u010det graf\u016f metrik, kter\u00e9 vid\u011bl p\u0159edt\u00edm, ho d\u00e1vno p\u0159esv\u011bd\u010dil, \u017ee standardn\u00ed p\u0159\u00edstup nebude fungovat, a \u017ee kdy\u017e jen vytvo\u0159\u00ed graf (i kdyby byl cohortn\u00ed,<\/a><\/noindex>), nebude to m\u00edt \u017e\u00e1dn\u00fd smysl.<\/p>\n

Co te\u010f d\u011blat?\u2026<\/a><\/noindex><\/p>\n

Metrika je jako oby\u010dejn\u00fd d\u0159ev\u011bn\u00fd prav\u00edtko. M\u011b\u0159en\u00ed proveden\u00e1 s jeho pomoc\u00ed ne\u0159eknou p\u0159\u00ed\u010dinu, pro\u010d <\/b> pro\u010d by m\u011b\u0159en\u00fd objekt m\u011bl m\u00edt pr\u00e1v\u011b tu d\u00e9lku, kterou uk\u00e1zalo. Prav\u00edtko pouze uk\u00e1\u017ee jeho velikost, a nic v\u00edc. Nen\u00ed to filosofick\u00fd k\u00e1men, ale jen d\u0159ev\u011bn\u00e1 deska, kterou m\u011b\u0159\u00edme.<\/p>\n

\"Nerezov\u00e1 krysa\" jeho obl\u00edben\u00e9ho spisovatele Harryho Harrisona v\u017edy \u0159\u00edkala: my\u0161lenka mus\u00ed dos\u00e1hnout dna mozku a tam si odpo\u010dinout, proto po n\u011bkolika dnech ne\u00fasp\u011b\u0161n\u00e9ho tr\u00e1pen\u00ed se Ivan rozhodl zam\u011b\u0159it na jin\u00fd \u00fakol\u2026<\/p>\n

Po p\u00e1r dnech, kdy\u017e \u010detl \u010dl\u00e1nek o internetov\u00fdch obchodech, Ivan najednou pochopil, \u017ee v\u00fd\u0161e pen\u011bz, kter\u00e9 internetov\u00fd obchod z\u00edsk\u00e1v\u00e1, z\u00e1vis\u00ed na chov\u00e1n\u00ed n\u00e1v\u0161t\u011bvn\u00edk\u016f webu. Pr\u00e1v\u011b oni, n\u00e1v\u0161t\u011bvn\u00edci\/klienti, p\u0159ed\u00e1vaj\u00ed obchod\u016fm sv\u00e9 pen\u00edze a jsou jejich zdrojem. Na kone\u010dnou \u010d\u00e1stku pen\u011bz, kter\u00e9 obchod z\u00edsk\u00e1, maj\u00ed vliv zm\u011bny v chov\u00e1n\u00ed klient\u016f, a ne nic jin\u00e9ho.<\/p>\n

Z toho vy\u0161lo, \u017ee pro zm\u011bnu m\u011b\u0159en\u00e9 veli\u010diny je t\u0159eba ovlivnit ty, kte\u0159\u00ed tuto hodnotu vytv\u00e1\u0159ej\u00ed, tj. pro zm\u011bnu mno\u017estv\u00ed pen\u011bz internetov\u00e9ho obchodu je t\u0159eba ovlivnit chov\u00e1n\u00ed klient\u016f tohoto obchodu, a pro zm\u011bnu doby dod\u00e1n\u00ed v DevOps je t\u0159eba ovlivnit t\u00fdmy, kter\u00e9 tuto dobu \"vytv\u00e1\u0159ej\u00ed\", tj. vyu\u017e\u00edvaj\u00ed DevOps ve sv\u00e9 pr\u00e1ci.<\/p>\n

Ivan pochopil, \u017ee metriky DevOps by rozhodn\u011b nem\u011bly p\u0159edstavovat pouze grafy. M\u011bly by p\u0159edstavovat n\u00e1stroj pro hled\u00e1n\u00ed<\/b> \"vynikaj\u00edc\u00edch\" t\u00fdm\u016f, kter\u00e9 formuj\u00ed kone\u010dn\u00fd \u010das dod\u00e1n\u00ed.<\/p>\n

\u017d\u00e1dn\u00e1 metrika nikdy neuk\u00e1\u017ee p\u0159\u00ed\u010dinu, pro\u010d n\u011bjak\u00fd t\u00fdm dlouho dod\u00e1val distribuci, pomyslel si Ivan, nebo\u0165 ve skute\u010dnosti m\u016f\u017ee b\u00fdt d\u016fvod\u016f milion a mal\u00e9 voz\u00edky, a ty mohou b\u00fdt zcela ne-technick\u00e9, ale organiza\u010dn\u00ed. Tedy maxim\u00e1ln\u011b, co lze od metrik o\u010dek\u00e1vat \u2013 to je ukazatel t\u00fdm\u016f a jejich v\u00fdsledk\u016f, a pot\u00e9 se stejn\u011b bude muset j\u00edt k t\u011bmto t\u00fdm\u016fm osobn\u011b a zjistit, co se u nich stalo. <\/p>\n

Na druhou stranu, v Ivanov\u011b spole\u010dnosti existoval standard, kter\u00fd vy\u017eadoval, aby v\u0161echny t\u00fdmy testovaly verze na n\u011bkolika st\u00e1nk\u00e1ch. T\u00fdm nemohl p\u0159ej\u00edt na dal\u0161\u00ed str\u00e1nku, dokud nepro\u0161el p\u0159edchoz\u00ed. Vypl\u00fdv\u00e1, \u017ee pokud bychom proces DevOps p\u0159edstavili jako sekvenci proch\u00e1zen\u00ed st\u00e1nkami, metriky by mohly ukazovat \u010das, kter\u00fd t\u00fdmy str\u00e1vily na t\u011bchto st\u00e1nk\u00e1ch. Znalost\u00ed st\u00e1nku a \u010dasu t\u00fdmu by bylo mo\u017en\u00e9 konkr\u00e9tn\u011bji mluvit s n\u00edm o p\u0159\u00ed\u010din\u00e1ch.<\/p>\n

Ivan se dlouho nerozm\u00fd\u0161lel, zvedl telefon a zavolal n\u011bkoho, kdo se dob\u0159e vyznal v nitrech DevOps:<\/p>\n

\u2014 Denisi, pros\u00edm t\u011b, d\u00e1 se n\u011bjak zjistit, \u017ee t\u00fdm pro\u0161el t\u00edm \u010di on\u00edm st\u00e1nkem?
\n \u2014 Samoz\u0159ejm\u011b. N\u00e1\u0161 Jenkins vyhod\u00ed vlajku, pokud verze \u00fasp\u011b\u0161n\u011b pro\u0161la (byla testov\u00e1na) na st\u00e1nku.
\n \u2014 Super. A co je to vlastn\u011b ta vlajka?
\n \u2014 To je oby\u010dejn\u00fd textov\u00fd soubor typu \u201estand_OK\u201c nebo \u201estand_FAIL\u201c, kter\u00fd \u0159\u00edk\u00e1, \u017ee verze pro\u0161la nebo nepro\u0161la st\u00e1nkem. Ch\u00e1pav jsi, co t\u00edm mysl\u00edm?
\n \u2014 V principu ano. P\u00ed\u0161e se do t\u00e9\u017ee slo\u017eky v \u00falo\u017ei\u0161ti, kde je verze?
\n \u2014 Ano.
\n \u2014 A co se stane, kdy\u017e verze neprojde st\u00e1nkem? Bude t\u0159eba ud\u011blat novou verzi?
\n \u2014 Ano.
\n \u2014 No ok, d\u00edky. A je\u0161t\u011b ot\u00e1zka: Ch\u00e1pu spr\u00e1vn\u011b, \u017ee jako datum pr\u016fchodu st\u00e1nkem mohu pou\u017e\u00edt datum vytvo\u0159en\u00ed vlajky?
\n \u2014 Absolutn\u011b!
\n \u2014 Super!<\/p>\n

Nad\u0161en\u00fd Ivan polo\u017eil sluch\u00e1tko a uv\u011bdomil si, \u017ee v\u0161echno d\u00e1v\u00e1 smysl.
