DailyRollingAppender - How does it know when to rollover?
I am trying to use LOG4J on OpenVMS. However, my logger is not rolling over
on OpenVMS. So I want to know how the code is determining when the log file
should be rolled over. Below I am posting my code and properties file. The
same code works on windows (of course, I have different properties file that
loads on windows). For completeness sake, I am posting both properties
files.
package com.name.webpublishing.webpublishing;
public class WebPublishingApp {
public static Logger logger = getLogger();
private static Logger getLogger() {
try {
String osName =
System.getProperty("os.name").toLowerCase().equals("openvms") ? "openvms" :
"windows";
InputStream is =
WebPublishingApp.class.getClassLoader().getResourceAsStream("/com/name/webpublishing/webpublishing/log4j_"
+ osName + ".properties");
Properties props = new Properties();
props.load(is);
PropertyConfigurator.configure(props);
System.out.println("LOADED PROPERTIES!!!");
} catch (IOException ignored) {
if (SeflWebPublishingServlet.DEBUG) {
ignored.printStackTrace();
}
// just use default
}
return Logger.getLogger(WebPublishingApp.class);
}
}
openvms properties - log4j_openvms.properties

Posted by Marc Farrow <ma...@gmail.com>.
LOG0: is a logical on OpenVMS (similiar to a 'symbiant' or whatever it is
called on Unix/Linux). This is a valid directory structure on the O.S.
I will check the privileges for the account which Tomcat is running under to
verify.

What is "LOGO:"?
And are you sure the user the application runs under has sufficient access to create/rename files in whichever directory it is attempting to write to?

I finally got around to this again. I changed the rollover time to be in seconds so I should get a new log with each execution. When I run the app, I get a new log, but the rolled over file is not created. I cannot find a file with my matching DatePattern. Below is my Properties file.

RE: DailyRollingAppender - How does it know when to rollover?
Posted by Marc Farrow <ma...@gmail.com>.
I finally got around to this again. I changed the rollover time to be in
seconds so I should get a new log with each execution. When I run the app,
I get a new log, but the rolled over file is not created. I cannot find a
file with my matching DatePattern. Below is my Properties file.
log4j.rootLogger=WARN, R
log4j.appender.R=org.apache.log4j.DailyRollingFileAppender
log4j.appender.R.File=LOG0:MyLogFile.log
log4j.appender.R.DatePattern='.'yyyy-MM-dd-mm-ss
log4j.appender.R.layout=org.apache.log4j.PatternLayout

RE: DailyRollingAppender - How does it know when to rollover?
Posted by Matt Brown <Ma...@citrixOnline.com>.
Just a suggestion, but if this is a development server, and the application is already getting re-deployed more than daily, why not experiment with a smaller rollover time (daily or hourly)? Just to make sure that DailyRollingAppender isn't somehow borked in your combination of OS / app server / application.

I checked the log file for my container (Tomcat) and there were no error messages that I could see for any rollover messages. However, I guess I am going to have to wait til next month to verify. Since my container is Tomcat and my container gets restarted fairly often (multiple times a day because this is a our development server), could this affect the rollover logic?

I checked the log file for my container (Tomcat) and there were no error
messages that I could see for any rollover messages. However, I guess I am
going to have to wait til next month to verify. Since my container is
Tomcat and my container gets restarted fairly often (multiple times a day
because this is a our development server), could this affect the rollover
logic?
Thank you,

Re: DailyRollingAppender - How does it know when to rollover?
Posted by Paul Smith <ps...@aconex.com>.
the first logging event _after_ the time period computed should roll
the file over, however if there is any failure (perhaps because
another process has the file handle open, a common problem on
Windows), the rollover can fail, and you'll need to wait to the next
window (another month).
When the failure occurs, it does log to StdErr (from the source code
to DailyRollingFileAppender):
protected void subAppend(LoggingEvent event) {
long n = System.currentTimeMillis();
if (n >= nextCheck) {
now.setTime(n);
nextCheck = rc.getNextCheckMillis(now);
try {
rollOver();
}
catch(IOException ioe) {
if (ioe instanceof InterruptedIOException) {
Thread.currentThread().interrupt();
}
LogLog.error("rollOver() failed.", ioe);
}
}
super.subAppend(event);
}
It tries it's best to continue logging until next roll over period.

This is a fairly simple question. Does anyone that maintains or create LOG4J
read these posts anymore?
Thanks.

Also, to give further information. In Java, you cannot read the "created"
date on a file as only certain operating systems understand it (namely,
OpenVMS and Windows). So, how does the logging engine know when to roll
over? Is it looking inside the log file for date patterns? Here a sample
of my logging file.

RE: DailyRollingAppender - How does it know when to rollover?
Posted by Marc Farrow <ma...@gmail.com>.
Yes, this is what I am wanting.
The original log file was created in April and now when items are written to
file the log file still has not been rolled over.
Since the application is writing to the specified log file, then wouldn't
that mean that these properties posted would be the ones being used?
Thanks.

RE: DailyRollingAppender - How does it know when to rollover?

The date pattern that you have:
log4j.appender.R.DatePattern='.'yyyy-MM
Will only roll the files over on a monthly basis. Just want to be sure that this is what you intend?
If this is the intended behavior, I'd check to make sure that a different log4j configuration file isn't being loaded from somewhere in the OpenVMS environment. You can enable the -Dlog4j.debug system property to be able to see which config file log4j is using.
