Take a look at Telegraf. It does support tailing logs using input plugins logparser and tail. To export metrics as prometheus endpoint use prometheus_client output plugin. You also may apply on the fly aggregations. I’ve found it simpler to configure for multiple log files than grok_exporter or mtail
Found the answer! According to this gradle forum post, there’s no public interface for coloring the output of the logger. You are free to use the internal classes, but those may change in future versions. In the gradle script, put at the top: Older Gradle: import org.gradle.logging.StyledTextOutput; import org.gradle.logging.StyledTextOutputFactory; import static org.gradle.logging.StyledTextOutput.Style; Gradle 3.3+: import … Read more
We just use this: <param name=”File” value=”${ALLUSERSPROFILE}/Company/Product/Logs/error.log”/> It works great. This line can simply be inserted into your current appender configuration: <appender name=”RollingFileAppender” type=”log4net.Appender.RollingFileAppender”> <param name=”File” value=”${ALLUSERSPROFILE}/Company/Product/Logs/error.log”/> </appender>
You need to set appendLineSeparator option to true for ch.qos.logback.contrib.json.classic.JsonLayout. Example of this: <configuration> <appender name=”STDOUT” class=”ch.qos.logback.core.ConsoleAppender”> <layout class=”ch.qos.logback.contrib.json.classic.JsonLayout”> <jsonFormatter class=”ch.qos.logback.contrib.jackson.JacksonJsonFormatter” /> <timestampFormat>yyyy-MM-dd’ ‘HH:mm:ss.SSS</timestampFormat> <appendLineSeparator>true</appendLineSeparator> </layout> </appender> <root level=”debug”> <appender-ref ref=”STDOUT” /> </root>
I don’t think that you can overwrite logback.xml-definitions from an included file. But I have an approach that solves your question regarding overriding the root-logger-level, using variable substitution with default values: logback.xml <configuration> <include file=”includedFile.xml” /> <!– STDOUT appender stuff –> <root level=”${root.level:-DEBUG}”> <appender-ref ref=”STDOUT” /> </root> <configuration> includedFile.xml <included> <!– override the default value; … Read more
Add or replace the ${exception} tag in the layout config to ${exception:format=tostring} <targets> <target name=”errorLogFile” xsi:type=”File” fileName=”errors.txt” layout=”${message} ${exception:format=tostring}”/> </targets>
Basically, webpack-dev-server uses express to spawn a webserver. To enable seeing logs, one needs to set DEBUG environment variable as required by express export DEBUG=’express:*’ This started showing me logs of various requests received by webpack-dev-server. To disable the logs, set the environment variable empty again export DEBUG= This works even for loopback projects and … Read more
The accepted answer was written before the sink Serilog.Sinks.Http existed. Instead of logging to file and having Filebeat monitoring it, one could have the HTTP sink post log events to the Logstash HTTP input plugin. This would mean fewer moving parts on the instances where the logs where created.
