Verbose GC Log Format

Hi,
I am interested in using an open source tool called GCViewer (http://www.tagtraum.com/gcviewer.html) to visualize the data from the verbose GC logs. However, it does not currently support the latest jRockit VMs. In order for me to write a data reader that is capable of reading the verbose GC logs from the latest jRockit VMs, I would need to be able to determine the actual format used for the verbose GC logs. I have tried searching on the BEA website, but have been unable to locate any information relating to this. Any help or advice will be much appreciated.
p.s. The reason I am not using jRockit Mission Control is that I want to be able to compare the performance across different JVMs

The documentation is at: http://e-docs/jrockit/jrdocs/refman/optionX.html#wp999543
Note that we do not guarantee that this format will not change in the future.
Regards,
/Staffan

Turning down the verbosity of logging in search service

Hello old friends.
Our search node is generating 1.5gb of logs per day. how can i turn down the verbosity of the logging? I don't see any configuration files that get read, and the config mgr doesn't have anything about logging verbosity.

Here are 2 log file settings in the search area, not sure what they impact but I don't see many other log setting files.
Definitely let us know what you uncover though.
1)
Cluster.ini file at this path:
\bea\alui\ptsearchserver\10.3.0\cluster
# Logging
# The following settings may be used to override the default logging policies.
# For a given severity level specify a comma-delimited list of values
# corresponding to the logs which should receive log messages at that
# severity level. Acceptable values are trace,event,cluster,none.
# Note that internally log messages are routed either to the cluster log
# or the local logs. While a cluster log message may be echoed to the
# local logs, a local log will never be sent to the cluster log
#RF_LOG_DEBUG_OUTPUT=none
#RF_LOG_INFO_OUTPUT=trace

Archive Log Format Issues

Hi DBAs,
I have 2 Archive destination. My archive log format is ARC%S_%R.%T
But In my 1 location E:\app\Administrator\product\11.1.0\db_1\RDBMS format shows ARC00025_0769191639.001
2 location shows E:\app\Administrator\flash_recovery_area\BASKAR\ARCHIVELOG\2011_12_08\O1_MF_1_25_7G15PVYX_.ARC
SQL> select destination from v$archive_dest;
DESTINATION
E:\app\Administrator\product\11.1.0\db_1\RDBMS
USE_DB_RECOVERY_FILE_DEST
My Question is that, I am using this format only ARC%S_%R.%T
but it shows different format in each location. May i know what 's the reason behind this?
Thanks in Advance

If you are using other archive destination other than FRA it will creates as per LOG_ARCHIVE_FORMAT,
and the FRA configured then the archive format for FRA is O1_MF_1_25_7G15PVYX_.ARC
from your query it is clear that there are two destinations are configured, So if you dont want *.ARC* files, you have to disable FRA.
But recommended to use FRA easy to manage.

but according to cisco reference the format should be
May 2 23:07:23 10.160.205.10 %ASA-6-302015: Authorization denied (acl=xxx) for user 'xxxx' from xxx.xx.xx6.53/137 to xxx.xx.xxx.255/137 on interface Outside using UDP

How to set access.log format to "combined"

Hello,
I'm trying to get AWStats working on Solaris and have that working fine, but to get more information, I need to set the log format to "combined".
Question is: is there a way to modify what is output in the access.log?

SHOULD I RECOMPILE and specify the access method?
Should i change line 1131 in db4.cpp to DBTYPE type = DB_QUEUE; ???

Apache Log Format Question

Hi,
I need to set my Apache logs to combined for AWStats to work. In 10.6 server admin there seems to be no place to change the log format. Can any one tell me how I do this? I have multiple sites hosted so will I need to do it for each site?
Thanks
Paul

You'll need to change it directly in the config file for each site. They're in /etc/apache2/sites, with names starting with a site ID number and ending in .conf. You need to change the CustomLog directive to something like
CustomLog "/var/apache2/access_log" combined
...and then restart Apache ("sudo apachectl graceful" will do the trick).

Change log format error

I've been syncing three computers and my iPod with no problem for years. I've just had my G4 iMac monitor replaced, and ever since when I try to sync this machine I get the message "change log format error INTERNAL ERROR: unhandled error (change log format error)" and I can't sync. Any help would be appreciated.
G4 iMac Mac OS X (10.3.9)

Yes, you just need to add the option -showdate into the ttendaemon.options file.

Georgi, the company profile has a Default Locale. Also each user can have their Locale. The US format of MM/DD/YYYY can not be changed to October 6, 2010 as an example.
I would recommend that you submit a enhancement request to CRM On Demand customer care.

Data log format like JDK logging

Hello:
I'm working with SUNONE AS
Source classes belong my application use Java logging ( JDK 1.4.2 ) , but logs ( in instance's server.log ) don't be written in Java logging format, i.e, class name & method name where log method ( by example, info() ) call is invokated
How can I do for logging calls into my code to write in Java logging format ? How I can to configure my SUNONE AS ? Must I change logging properties file in jre/lib ?
Thanks in advance

Hi,
I think you change the format as you using TraceFormatter class.
According to the pattern you give in the constructor your format will change.
It is that pattern that determines.

Extended Log Format Issue

Hello,
I am rather new to BEA, and I am experiencing a little bit of a problem here. I am trying to configure the access logs in order for them to generate output concerning Browser information. I have gone through and was successfully able to change the configuration to extended. The browser information is now displayed.
I have one MAJOR problem. When using the common log format, the usernames are logged just fine. But when I changed to the extended format, I only get a value of '-'. I believe all of my configuration is correct according to w3c standards, as I am using 'cs-username' in the '#Fields' directive. I have been searching all over for information reguarding how this field can be documented, but I cannot find anything.
I have even gone out and tried to configure our apache logs to read this field, and yet I get the same '-' value there as well.
If anyone could PLEASE help me in this matter, I would greatly appreciate it, as I am going down a river without a paddle on this one.
Thanks in advance,
Garret

Hello,
Have you read through common log format doc and Enabling and Configuring HTTP Access Logs? Oddly they don't mension cs-username in the supported field identifiers section. You could try the common log format field name: auth_user. Or a custom identifier. I would also raise a support case with BEA if you don't get anywhere to make sure they do actually support this field.

Proxy log format

Just looking for opinions on what everyone is using for log formating.
We are looking at log analysis tools and some require different log formats.
We are currently using extended2 log format.
TIA.
joe.

Extended2 seems to be a popular format. Quite a lot of people seem to use the default
format plus a few useful parameters like "cache finish status", etc, added.

Arch log format in asm

I am on single node asm with 10gr3. I changed the arch log format to %t_%s_%r.arc but the files are still getting created as thread_1_seq_90.459.653928775
I have bounced the db already.
SQL> show parameter archive_fo
NAME TYPE VALUE
log_archive_format string %t_%s_%r.arc
SQL>
What else to be setup in order to correct the format?
Thanks.

I believe what you are observing is Alias created by Oracle.
Check logs available at your destination defined by "log_archive_dest_1"
e.g In my case it is +DATA/test
ASMCMD>cd DATA/test
ASMCMD> ls
1_7_653875700.dbf
2_6_653875700.dbf
Now I switch to directory storing alias
ASMCMD>cd ARCHIVELOG
ASMCMD>cd 2008_05_06
ASMCMD>ls
thread_1_seq_7.425.654030021
thread_2_seq_6.363.654040811
Is it clear?

Weblog Log Format

hi,
can anybody tell me how i can change the log format in weblog5.1
to NCSA format (extended)
Regards,
Bibin

Looks like the bug CSCin07036.

Extended Log Format

Does iPlanet v6 support the Extended Log format [http://www.w3.org/TR/WD-logfile.html]?
If so, would anyone recommend using the time-taken field to monitor page download times?

Web Server does not directly support the Extended Log Format. In most cases, however, the flex-log format that Web Server does support can be manipulated to log the same data in the same order as the Extended Log Format.
If you want to request time from Web Server then do this:
1) Enable Statistics Gathering in the server (see the Performance and Tuning Guide for details), and
2) Add \"%duration%\" to your flex-log init line in the magnus.conf (or via the Log Format Adming UI screen).
This will log the time taken for a request to be completed to the access log.
