[summary] log4j on sentry practice

1. SentrySentry is an open source error tracking tool that allows developers to monitor and repair crashed programs in real time, iterate continuously and improve efficiency. After the Sentry is integrated into the program code, the exception information can be sent to the Sentry service, and the alarm notification through mail, nails and other alarm can be realized by configuring the Sentry plug-in. Sentry official website: Appender of log4j is provided in https://sentry.io/welcome/2 and log4j/logback on sentrySentry, and specific level logs in log can be sent to Sentry.

Integrate Sentry into the code

Use Maven:

Io.sentry

Sentry-logback

1.7.5

Use SBT:

LibraryDependencies + = "io.sentry"% "sentry-logback"% "1.7.5"

Configuration of logback.xml

% d {HH:mm:ss.SSS} [% thread]%-5level% logger {36} -% msg%n

WARN

3. Configure DSN (Data Source Name) of Sentry

There are the following centralized implementation methods.

Sentry.properties configured under classpath

Dsn= https://public:private@host:port/1 is configured in Java system Properties (Java System Properties)

Java-Dsentry.dsn= https://public:private@host:port/1-jar app.jar is configured in the system environment variable

SENTRY_DSN= https://public:private@host:port/1 java-jar app.jar is implemented in code

Import io.sentry.Sentry

Sentry.init ("https://public:private@host:port/1");"

I used the second way to configure the JVM parameters of the startup program
