Spring-boot-admin: How to download and view log?

[Mike-the-one]

Hi, I am using 1.5.7 SBA, and my other existing app (log4j2) is at 1.5.14.

That app registered to the SBA successfully, I can see details/ . Hoever the Logging tab only shows the logging level button. I want to be able to download logs and flow/view logs, how can I do that?

thanks

I was using console logging, after I switched to file, still no log tab, or no buttons to download or view log...

this is my log config

<?xml version="1.0" encoding="UTF-8"?>
<Configuration monitorInterval="60">
    <Appenders>
        <RollingFile name="App-File-Appender" fileName="d:/temp/my/log.log" 
                     filePattern="d:/temp/my/log-%d{yyyy-MM-dd}-%i.log">
            <PatternLayout>
                <Pattern>[%-5level] %d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %c{1} - %msg%n</Pattern>
            </PatternLayout>
            <Policies>
                <SizeBasedTriggeringPolicy size="10MB" />
            </Policies>
            <DefaultRolloverStrategy max="10"/>
        </RollingFile>
    </Appenders>

    <Loggers>
        <logger name="org.springframework" level="info" additivity="false">
          <AppenderRef ref="App-File-Appender" />
        </logger>
        <logger name="org.hibernate" level="info" additivity="false">
          <AppenderRef ref="App-File-Appender" />
        </logger>

        <Root level="info">
            <AppenderRef ref="App-File-Appender"/>
        </Root>
    </Loggers>
</Configuration>

I checked d:/temp/my has the log file.

The /logfile endpoint of spring boot actuator needs to be enabled. Please read the boot docs on how to achieve that, this is no SBA issue.

Hint: there is a management.endpoint.logfile.external-file property that you can use to activate the logfile input (in case you don't set logging.path or logging.file)

@joshiste thanks. It is working now. I had to specify logging.file in my config. logging.path doesn't work.

As you can see I have a logging.config, which points to a log4j2.xml file, and inside it, I use a roller appender. Is there way to let SBA show these old logs as downloadable file? (in my logging config, I set the max size of the log is 10M, so if it reaches this size, it will rename to ,log and then create a new log file. So I would like to download these .log from SBA. Is this supported?

thanks

[joshiste]

as the spring boot actuator endpoint has no support for this, sba also doesn't has
