Jak vytvořit tutoriál Skywalking pomocí Dockeru
Tento článek vysvětluje, jak integrovat ASP.NET Core a Skywalking dohromady.
Nejprve vytvořte nový projekt MVC pro asp.net Core 3.1 s názvy: sky-apm-demo
Příkaz Nuget Install:
Nainstalujte nástroj SkyAPM.DotNet.CLI
Tento nástroj nám pomáhá generovat skyapm.json konfigurační soubory pomocí parametrů příkazové řádky, ve skutečnostiNezáleží na tom, jestli ho nainstalujete nebo ne, a tady je jáma.
Generované konfigurační soubory HeaderVersions a ProtocolVersion jsou nesprávné, což vede kData nelze zasílat do služby Skywalking。
Správná konfigurace je následující:
Dokumentace konfigurace:Přihlášení k hypertextovému odkazu je viditelné.
Zkopírujte soubor skyapm.json do kořene našeho projektu.
Upravte soubor /Properties/launchSettings.json tak, abyste přidali konfiguraci ASPNETCORE_HOSTINGSTARTUPASSEMBLIES následovně:
Současně vytváříme v řadiči dvě nové metody, a to následovně:
Spusťte naše webové stránky a zkuste získat jinou URL adresu následovně:
Skyapm logy můžeme zobrazit ve složce logs kořene projektu, a to následovně:
