The answers have mentioned both, $$PLSQL_LINE & DBMS_UTILITY.FORMAT_ERROR_BACKTRACE. But I would like to add a bit about the difference between them: Predefined Inquiry Directives $$PLSQL_LINE & $$PLSQL_UNIT PLSQL_LINE predefined inquiry directive is a PLS_INTEGER literal value indicating the line number reference to $$PLSQL_LINE in the current program unit. From its definition, PLSQL_LINE is not suitable … Read more
Quoting the man page and assuming you have a Combined Log Format: If we would like to process all access.log.*.gz we can do one of the following: # zcat -f access.log* | goaccess –log-format=COMBINED OR # zcat access.log.*.gz | goaccess –log-format=COMBINED On Mac OS X, use gunzip -c instead of zcat.
I’m developing OtrosLogViewer. It’s on Apache license and highly active. It has some interesting new features like automatic log events marking, highlighting part of log message, human friendly formatting soap messages and others. Disclaimer: I am the author of OtrosLogViewer
To expand on the link which Sikorski put in the comments: NDC In NDC, the N stands for nested, meaning you control a single value with a Stack. You “push” a string, then you can “push” another whenever processing dictates; and when processing is complete you can pop it off to see the former value. … Read more
Generally your own code is at the beginning of the classpath. Because of this, one way to do it is to create your own org.slf4j.impl.StaticLoggerBinder class: package org.slf4j.impl; import org.slf4j.ILoggerFactory; import org.slf4j.spi.LoggerFactoryBinder; /** * Force tests to use JDK14 for logging. */ @SuppressWarnings(“UnusedDeclaration”) public class StaticLoggerBinder implements LoggerFactoryBinder { private static final StaticLoggerBinder SINGLETON = … Read more
If you do not want to bother with logrotare you can use a full python/gunicorn solution using python logging facilities. Create a file named log.conf with the content below. This will rotate the error log file and access log file daily and will keep the logs for 90 days. Log level is set to INFO. … Read more
Although a very old question, the same question has been haunting me this last couple of weeks. Here is my little contribution to the hive-mind: I found that for a lightweight client or client/server application using a simplistic, lightweight log viewer like log2console with NLogViewer target’ filled with additional parameters fields made it both easy … Read more
It looks like you’ll need to append to the JVM arguments used when launching your tasks/jobs. Try editing conf/spark-defaults.conf as described here spark.executor.extraJavaOptions=-Dlog4j.configuration=file:/apps/spark-1.2.0/conf/log4j.properties spark.driver.extraJavaOptions=-Dlog4j.configuration=file:/apps/spark-1.2.0/conf/log4j.properties Alternatively try editing conf/spark-env.sh as described here to add the same JVM argument, although the entries in conf/spark-defaults.conf should work. If you are still not getting any joy, you can explicitly … Read more
You can have the below pattern in your script (tried in Groovy Editor). import java.util.logging.Logger Logger logger = Logger.getLogger(“”) logger.info (“I am a test info log”) The above logs output to STDOUT. In order to log it to a file, you have to create a logger using getLogger. Follow the API for your convenience.
A cleaner solution is to use standard python logging module with a custom distributed handler to collect log messages from all nodes of the spark cluster. See “Logging in PySpark” of this Gist.
